I have been searching forums the past few weeks or so for a fix or a workaround for this. One workaround exists but it does so by disabling the suspect menu button. There's lots of evidence that this is a hardware issue, but there are lingering variables that remain unanswered, the main one being why some phones develop this problem after a period of time (say a year or so) of good behavior. Some people have taken the phone apart and cleaned it and it went away, some suggested the wi-fi (really?). Try those things first if you'd like, but they didn't work for me. This is the result of my experimenting and some observations i made. Because of the relative ease of getting a used E4GT on ebay/craigslist (I scored one in very nice condition from ebay for 50) some people don't really have the option of walking into a store and getting their phones swapped and like me probably were getting annoyed at getting the menu popping up in low signal areas and don't want to resort to workarounds.
If your phone is within warranty, don't bother trying these suggestions. Easiest to get it swapped out. (unless you have already done that multiple times) :laugh:
OPTION 1:
Here is a hack that sounds like a solid fix, it makes a lot of sense though, you are essentially using a small magnet strip as a crude RF shield on the flex connector which inhibits RF interference apparently - ingenious if you ask me!!.
Since the fix I offered is firmware based (meaning it still may not work, although I haven't had mines fail yet. YMMV, these phones have their own personalities ) it sounds logical that this one will address the bigger problem, which as jdsingle76 mentioned, is the hardware, so if you're feeling brave I'd do this fix.
This fix requires you take apart your phone
http://forum.xda-developers.com/showpost.php?p=44639715&postcount=8
(This is for informational purposes, as the first fix pretty much negated this one - although it worked for me, it requires having to go back to a modem that could possibly have worse performance than your current one...)
OPTION 2:
If you want to stay with the stock TW 4.1.2 ROM, this won't help you.
Do this at your own risk! This fix assumes you know how to flash firmware to the phone!
1. Grab the stock ICS rom http://www.rwilco12.com/downloads.php?dir=Files/Devices/ here (the Boost/Sprint/Virgin ones)
2. Flash it to your phone using ODIN (This will erase everything, so back up your data!)
3. Now that you are back to ICS, what we are going to do now is flash different modem firmware. On rwilco's website, go to your respective carrier (come to think of it since it's the same hardware they're all the same?) and in the GB subfolder download the One Click EL26 firmware. Reason is that one user reported that the phantom menu problem incidents started after the EL29 firmware had been rolled out. I do agree that updates to firmware is supposed to 'enhance' the performance of hardware, but for my purposes I'd take stability over a menu button gone crazy :good:. So yes, this might hurt your phones performance a lot or a little...In case you are wondering why a GB modem for an ICS build? Thankfully, GB and ICS modems are interchangeable but not JB (you won't have data at all).
http://www.rwilco12.com/downloads.p...sung Galaxy S2 (Sprint) (SPH-D710)
/Modems/GB
4. Flash that modem. Reboot and check data still works. Update Proflie / PRL (don't really need to do this if there is data, but just to cover your bases) Done.
For a week now I have been running this, driving to fringe coverage areas and even the server room surrounded by walls and walls at work to get it to go mad. Hasn't..... yet. (observations still in progress - I'll try and run a network signal info app and document it)
UPDATE: Yesterday before my commute home I decided to give the EL29 modem a shot, so I flashed it and off I went. Driving through the fringe areas, what do you know - the pesky menu button problem that I had not missed came back! Reflashed EL26 and all was good again..
The cool thing is, you're not stuck with ICS going this route. You can further this and root the phone and go beyond 4.1.2 and install 4.2.2. But that is where it ends - 4.3 has no support for WiMax. XDA has some great 4.2.2 roms - I am running SlimBean, but Dirty Unicorns and Carbon are good IMHO. Keep in mind that data speeds won't be anywhere near TW speeds if you choose not to stay with the stock TW ICS rom. Additionally, make a nandroid backup of your system before installing a new ROM, if you need to go back for some reason.
I ran some tests on the ICS build / EL26 modem combination and quite honestly the performance was decent (If I have time to flash back to it I'll post some numbers)
I hope this helps some of you to not throw your phone across the room. Also spread the word as it seems like people search the forums but they never seem to find the fix because of varying key words they search on (I found the magnet hack just the other day).

This sounds interesting, but everything I've read, and having personally sent my phone back to Sammy twice gives all indications that this is a hardware issue and not a software issue. It has something to do with a faulty heat shield that causes some type of heat exchange. The reason you may not be having issues at the moment is that the older, less robust GB build doesn't put as much strain on the phone, thus not heating it up as much? Just a thought, but great observations nonetheless.

That sounds right to me. From what I have read online the 3g chip in low signal areas strain to contact the towers and in its high powered frenzy it triggers the neighboring chip on the board that controls the softkeys, making it think that the menu button was pressed and hence the menu button craziness. I'm thinking the older firmware didn't ramp up the modem activity as much in low coverage areas, so it never reaches that threshold. This would suggest that the phone's range takes a hit, as the chip doesn't get too aggressive seeking out a signal; however, where I live my range didn't seem to change. I may even try going beyond the EL26 firmware to see where exactly is the threshold for my phone is in this area, as the one downside I noticed is my 4g speeds are not that great (but better than 3g that's for sure :laugh
I am curious as to why you made a thread on this when there is multiple threads on this topic. One of which I created that does not require half the steps you have nor does it require downgrading or sacrificing data performance... My point is, this thread is more or less, unnecessary.

Just my observations. I used the search function on several words to find a way to retain the use of the capacitive buttons as the threads that I read presented workarounds and there was individuals that didn't want to give up the button functionality (something about having a button there and knowing it doesn't do anything kind of makes some people crazy). I didn't find any reference to the magnet hack until yesterday when I typed in 'ghost menu' instead of 'phantom presses' or 'random presses'.
Also didn't want to necro post /hijack existing threads. Sorry if I offended you :good:
Thanks for the thread. My ebay phone w/sero hack was deferentially not up for warranty service. I had never seen the fridge magnet mod before. I just spent 5 min installing it myself, and I will see if it resolves the issue. :good: So far so good. I will report back if it fails for me.
BTW for anyone trying that hack. The first time the phone is opened it is a royal pain, almost feeling like impossible. A tip is to get the side started, then to to the bottom/usb area. The headphone jack extends just a little further into the case making it a bit longer and better for the last part to take off because of that. After the first time taking the phone apart is much less painful.
Oh and really tighten those screws down super tight. The screws not making the case super tight will cause the contact antenna points to make poor connection leading to signal and gps loss.

Well at ~$28/m including tax (still have employer discounts on top of the $30/mo rate) w/unlimited 3g data I can't find a better deal than my old sero plan. I did get a letter from sprint last month when I downloaded 60GB of data over that. oooppps.
Well it has been more than 24 hours, and I have not seen a single ghost touch since installing the magnet. :good:
Hopefully it is fixed for good.

How's data speeds? I stuck one in mines yesterday as well. It was bulging a lil, however, and I also noticed my data speeds wasn't that great. took out the magnet, took out the cushioning in that square region, and trimmed the magnet a lil more so it was thinner and voila'! I even went back to stock 4.1.2 ROM to 'increase' the chances of it flipping out. So far so good..:good:.

Well if your case was bulging then there is a good chance that one of the antenna contacts was not making good contact. That could kill your speed. I would say that you used way to thick of a magnet. I used a piece that was probably as thick as a piece of poster board. It fit inside of the little square of plastic on the case cover next to the screw hole quite nicely.
Still no ghost touches to date.

Yeah, the piece of magnet i stuck in there was a tad too big
Well, I guess this means this fix works! It's working for mines as well, even on the stock ROM. I drove through the fringe areas and no symptoms yet.
I think I may have cut the magnet a little too small (slightly smaller in size than the OE peace it is covering) as the instances are greatly reduced, but still happened twice. Looks like I need to go back to the bench and put in a bigger piece. I never use those buttons though, so I wouldn't mind removing them via the software mod posts, but I'm lazy and find it a lot easier to open the phone and put this 'shielding' in vs. trying to figure out software mods.

I have have experienced phantom touches on my phone if the gold contacts on the motherboard and on the back of the phone are dirty; as well as loose connectors on the motherboard. I would suggest cleaning the contacts and re-attaching and cleaning the motherboard connectors, try those methods before trying the software hacks, and you may not even need the magnet either.
Good Luck!

I cant understand why a 200 dollar phone has such horrible signal strength. I have stock rom gb ( i am rooted though) running on my incredible 2, and my db level is always between -90 to -102 showing 1 bar or none while my wifes droid x shows -72db to -70 at all times all over our house and everywhere we go. It gets even worse when I put a silicone case from verizon on it. Is there anything I can do"? I had a thunderbolt that had slightly better signal but this is ridiculous, anyone else experiencing this?
I think if this continues , I might not have a choice but to trade this phone for something else. I would really like to keep this though so any suggestions would really be appreciated thanks
Unless the devices were calibrated on the same equipment, you can't rely on the accuracy of their signal strength measurements.
Are you having any REAL problems or do you just not like what your phone displays and perceive a problem? Mine shows between -80 and -100 usually and I get great call and data performance out of it.
Try going into settings-calls-then network. I changed from global to cdma and it seemed to help. Ymmv

Try a different back cover. The antenna is in that. May have a bad cover. Mine came with two and one of them gave me better signal than the other. Take it to verizon, they should switch it out for free. Mine gets awesome signal everywere.

Can anyone confirm or have you tried factory reset after GB? On Froyo I had decent/good signal, but after GB it's been horrible. I am steady with 1-2 bars even in areas I used to get full bars and my dBm is around 90-102. My battery has seriously been crap since and I keep hearing and have been told by HTC/Verizon to do a factory reset to fix it but I don't know if I want to. Just curious if anyone has done it.

that is correct. the antenna is in the back cover. try removing the back cover and watch as it loses signal completely. to make things worse though, it seems the antenna is focused at the bottom of the case.. so similiar issue to what the iphone 4 was having.
i wonder if there's small booster antennas you could stick on to the phone somewhere(sure sounds like nonsense but i'd give it a try).

that's how desperate i am...
i used to have these 'radiation blocker' stickers i put on my old moto razr. doubt they did anything either but my old job was throwing them away so thought 'why not'.
Mine is horrible as well. Just got the phone 2 weeks ago b4 unl. data went bye bye. My old samsung rogue got amazing reception but this doesnt. I have not dropped a call yet though so maybe the reception bar is just a "dummy" graphic?
No difference from froyo to gb either

This signal bar is definitely conservative. I've set the phone exactly next to my Galaxy Tab, both showing signal strength within 2 db of one another. The DInc2 showed 0 bars while the Galaxy Tab showed 2.
I know the extended battery with back cover gives me better reception then my standard cover. My phone loses signal, drops calls and isnt able to send texts or make calls sometimes while my wifes phone is able to and the wifi has been losing signal as well. On craigslist it goes
very interesting to know that the antenna is on the actual battery cover. i removed my cover and i wasnt able to see it (i assume it is built into the mold?)

What I called junk was not a signal booster. It was a sticker to be placed in the battery compartment purported to boost signal when it does nothing at all. They use to be very expensive ($20-$50) until it was proven they didn't work, then the price dropped ($1-free).
Real signal boosters (pieces of hardware which will actively boost/relay a signal) actually do something to boost signal, and they really work. They also tend to not be cheap.

Different from other electronics, cell phones have become the necessity of every one's daily life. If someone still has no idea of mobile phones, you must say that "Out!" of course except the senior citizens. To be honest, cell phones really bring us lots of benefits. We use it for talking, sending and playing. With it, our life can be modern one, without it, we will be live in the Mars, you know, know nothing about each other. But do cell phones have no disadvantages? Of course not, more and more people are using cell phones at the cost of other interests. Noises are everywhere, especially the one of mobile phones. What should we do, throw them away? It is a stupid behavior. Have you ever heard cell phone signal booster? It is a new kind of device to solve this problem, effective in blocking the signals of your cell phone and its nearby base station. one side, the mobile phone really benefits us a lot, but another side we also benefit from its noises for a long time, so the fight between the cell phone and cell phone jammer has been a hot topic in society now. Which side you stand by, jamming or not, it depends on you.

I never understood the gps deal. It seemed so sporadic. Mine always worked and I am stock. I used it last weekend on EH17 to drive 5 hours to saint louis and it was perfect the entire way there and back. Didn't cut out once. But you see some people worth working gps and others without it.

I have to agree on the gps sucking. On any drive over an hour I could expect to loose lock. I'd imagine if we looked in some of the other GSII forums we might get a clue.
the only thing i ever loved more about my evo then the epic was the gps....htc never gave me gps issues ever
when i had the bionic or droid x they both locked on quick
Backing up the GPS being just short of useless. Remember, just because YOU haven't experienced the problem doesn't prove there isn't one. On Eclair I had very little trouble, but on FroYo I would constantly lose signal mid-trip, having to frequently turn it off and back on to re-lock and hope I wouldn't lose it right when I was in the middle of complex turns or had missed a turn and needed re-routing. In the Gingerbread leaks it turned to completely useless, locking up 100% after as little as 10 seconds of use, requiring a full restart of the phone to be useful again.
So yes, the Epic's biggest flaw was its next-to-useless GPS, hands down. That said, most reviews of the entire Galaxy S line agreed the GPS was bad on all versions. So far I've heard nothing of the sort about the Galaxy S II phones in Europe which suggests the entire line will be similar, including our new Epic 4G Touches.

If you couldn't fix it then that wasn't the norm. I would have returned it to Sprint and got a different one within the first 30 days.
9 hour drives? No problem. Longest I've been on was 6 but the GPS didn't have any problems. The battery on the other hand...
got mine yesterday, used GPS with google nav and telenav. drove for about an hour in farm country Ohio. GPS took a few seconds longer to lock than my EVo but once locked didn't drop signal. Still a little early to tell but no obvious problems yet.

Since I don't know who you were responding to I will assume it was me. You know that goes both ways right. Just because YOU have experienced the problem doesn't prove there is one. I have used every official build and every gingerbread leak except EE03 and I have never had a single problem. I use GPS frequently. I have never had a lockup. I have always had an instant lock. And I have always been able to get within 10 meters with the average being 3 meters. However, I never said there wasn't a problem. I just said I never understood the issue as to why it worked for some and not others. You would think that it would be global if the hardware is identical. Makes me wonder if it has anything to do with location in respect to the satellites. Never tried to dig into it because fortunately I didn't have the issue. But I do hope that the touch is without issues because not having gps would be a deal breaker for me.

Just because he experienced the problem means that a problem exists. Whether it's a wide spread problem or a unique incident, the problem still exists. On the Epic forums people are constantly complaining about GPS issues. There are few fortunate ones like you who haven't had the same issues. I didn't have GPS issues for a while until my job had me drive long distances.

So if you brick your phone because of something you did is the phone bad. Is there a flaw in the phone? No. And again, I never said there wasn't a problem. Actually I said that there was a problem for some and not for others. The only point I was making is that I didn't understand why it worked for some and not others. I wish we could have found the root cause.
Generally speaking GPS on the galaxy S line sucked world wide. Generally speaking it appears that samsung fix this in the galaxy s II.
This is based on reading numerous reviews on both; though it is always possible they messed up on the epic touch as it is slightly different and has wimax; I'm expecting it to work like a charm.
-
I do wonder how many folks who tested gps on the galaxy s remember to ignore wifi triangulation when voicing a comment.
Forgot about this thread and started another a bit further down. I managed to sneak GPS status onto our demo phone yesterday and it locked to 9/10 sats in less than 2 seconds from inside. Accuracy was only at 30m when I cut it off, but it was indoors in a spot where my epic cannot lock at all. Pretty sure it's fixed.

I did spend a fair amount of time investigating the GPS issues on EC05. There are at least two problems: (i) GpsOne Xtra data that fails to download and update, eventually resulting in stale ephemeris and inability to get timely locks, and (ii) a RIL synchronization bug that results in the GPS crashing with 5% probability on every exit/switch of a GPS utilizing app.
The latter of those two problem is definitely confirmed and affects every EC05 Epic. However, if you only use Navigation once a day, you'll run into that bug an average once a month and might not even notice it. But it is possible to reliably reproduce.
The former of the two problems I never fully understood. The GPS should work as long as you reboot once a week, but we know folks whose phones chronically couldn't download new Xtra data on reboot, likely becuase it was attempting to do so "too quickly" after establishing a network connection. Forcing an Xtra download through GPS Test, GPS Aids, or with a patched framework resolved the issue for most of those folks. The remaining issue is that the ephemeris would still go stale very quickly (hours) on some phones, and an EFS/NVRAM clear appears to help that.
Part of the issue is that the "brokenness" of the GPS is somewhat subjective. It's entirey possible for the GPS to absolutely not be able to get an Xtra-assisted lock, but using almanac data still get one in 30-60s in a vehicle. For some folks, that might be "good enough" and wouldn't think there's much of a problem.

Just because he experienced the problem means that a problem exists. Whether it's a wide spread problem or a unique incident, the problem still exists. On the Epic forums people are constantly complaining about GPS issues. There are few fortunate ones like you who haven't had the same issues. I didn't have GPS issues for a while until my job had me drive long distances.

I think the opposite of what your saying is true. This problem isn't as wide spread as it seems. The few who have this problem are very loud about it and complain about it over the forums. Though I seriously doubt that they are the majority.
If fixing your gps doesn't work then you can always set it back to stock and take it in for repair. If they can't repair and you don't have insurance then you can pay a small fee for a epic with a working gps. I doubt anyone is forcing people to live with a phone that the gps doesn't work on.
Considering that it has a dedicated GPS chip "SiRFstarIV GSD4t GPS" I doubt that we are going to see the same issues.
The integrated GPS on the SoC stinks, and samsung knows that. Using the SiRFstarIV will solve 99% of peoples GPS problems.
engadget claims it is solid. fwiw. http://www.engadget.com/2011/09/15/samsung-epic-4g-touch-review/
Our calls were absolutely solid. The phone's reception is on par with the best handsets around, and we never suffered from dropped calls or degraded quality. Our calls came in absolutely clear, and we think the speakers go to 11 because we had to actually turn down the volume to comfortably hear the other end of the line. The same thing could be said about the loudspeaker for calls and music, which both came out loud and clear without needing to strain our ears or feeling like we needed to break out the headphones. However, the sound seemed a bit limited when watching a full-length blockbuster movie, though we believe this had to do with the quality of the movie itself and not the phone.Last but not least, we double-checked the GPS to make sure it wouldn't have similar concerns to the Galaxy S series, and weren' t disappointed. In several locations -- including a basement next to a window -- the GPS pulled up our location in less than ten seconds. Needless to say, this is definitely a sound improvement, one we imagine had special attention given to it throughout the course of the phone's development.

I have an extremely annoying issue. I've seen some posts reporting this on various boards, but it seems most people throw a default answer out there that it's a hardware issue. I'll explain why I don't think that's the case.
The menu that comes up with you press the "menu" capacitive key has been popping up and down rapidly and repeatedly when I'm in a low signal area. This didn't start happening until after Samsung/Sprint fixed the LOS issue. I'm thinking it has something to do with the way they fixed it, which I don't have any technical or general knowledge of. Most of the time, the screen and keys will not be responsive unless I hit the power key to turn the screen off and turn it back on. It's even more annoying since it vibrates everytime the key is "pressed". I don't think this is simply a hardware issue as the only time this presents itself is the same times the LOS issue used to. I'm sure it's tied to that fix somehow.
Is anybody else having this issue? This may be a long shot, but I installed the LOS Checker zip, (I forgot which dev created it), and never uninstalled it, but I've upgraded many roms since then and don't think it would still be installed.
If any of you do have this issue, did you ever install that LOS Checker zip?
Rom= Blazer Rom EL29 v3.8
Kernel = rogue 1.4.1
Started happening to me recently as well. Im running Calks still on GB with ICS theme. I haven't paid attention to my signal when it happens but you are right, turning off the screen does stop it momentarily. I agree this may not be a hardware issue as well. I've just been bearing it because I plan on changing phones soon anyway.
Edit: It just started happening after this post. Signal was at 1 bar...

I have this same issue. I never realized it correlated with low signal. The issue cropped up 3 times today and each occurrence was with low signal. Good eye sir.
Do any of you undervolt or use a kernel that runs less than standard voltages?
My device is undervolted quite a bit and was wondering if it may be part of issue as i don't remember having this problem prior to that.
I am removing my undervolts and will report back if i still have this issue.

I think its a hardware issue. Im running the same setup on my replacement phone and haven't had the issue since.
I experienced this ever since I got the phone back in september but I didn't wise up until the 14 day period ended. there are two threads in the Q&A section concerning this, one that i started and another that i contributed to.
I would be trying to text and the menu button would pop up and i would accidently hit something on the menu that came up bc the button spazzes out randomly and consecutively and sometimes for a solid 5 seconds, but like the rest of you im sure, it wasnt confined to any single app so it was impossible to find one thing to blame. it would have to be something system-related or hardware-related (btw i did flash the LOS checker some time ago)
I believed the low signal theory for a while, as well as having a corrupted flash. but I experienced the spasms with full bars of service AND after a complete Odin restore to stock everything without restoring any of my past data whatsoever. thus I deferred to the "default" that it is hardware-related.
that was months ago.
I got so fed up with it, i decided to do anything to make it stop. So, I recently opened up my device and took everything apart and found that the water indicator just above the capacitive buttons had been activated. keep in mind I DID NOT EVER have any encounter with water. in fact, the other water indicators were perfectly undisturbed. this pissed me off because that means there might have been an accident or something while they were being manufactured that would have damaged the button - idk just another theory.
This is my main piece of evidence supporting my claim that it is hardware-related:
I ended up breaking the screen trying to separate the glass from the digitizer (stupid, I know bc theyre fused together) so I ended up buying a new screen/digitizer. put it in myself. i haven't had it since. I'm running the EXACT same set up as before I replaced my screen and its been about a week and no instances. I would be experiencing the sporadic menu button randomly, several times a day but it has completely disappeared.
i suggest to you all: bring it in to Sprint if you bought it from them or invest in a new screen off ebay if you bought it from a 3rd party seller (Amazon, wirefly, letstalk), i got my new screen for $65 shipped and it was in pristine condition. now im living a happily-ever-after ending
i'll keep a close eye on this thread to help you all with your endeavors/theories though
if any of you plan on opening up ur device, i suggest you do some homework so as not to destory your phone - its still an amazing device. or you can just ask in this thread and i can give tips to everyone
good luck!!
Thanks for all the updates.. I've noticed I'll sometimes get this error, but my phone will be showing full bars where I KNOW I have a poor signal.. for instance, my elevator at work..
Is there any sort of logging app I could run and go into an area I know this will happen to find out what's going on?

sometimes the signal bars are inaccurate (like you described). your true signal is found in settings>about phone>status>signal strength. 0-1 bars is really about -90 to -100 dBm
devs use logcats to analyze issues with the internals
http://forum.samdroid.net/f38/tutorial-how-get-logcat-example-check-battery-drain-2543/
I just checked a few other boards and it seems a number of people have confirmed it correlates wih low signal. There are a few people that keep popping up on multiple threads stating it's a hardware issue, only because a new screen fixed it. I would be fine with that logic if there weren't so many people stating it correlates with low signal. Also, it seems most people haven't really experienced this issue until after the LOS fix. Now, at the same times I used to have LOS issues, I now have this. I'm guessing it has something to do with internals and whatever they did to update it may be separate from modems or roms, since people have gone back to stock and still experienced this issue.
I haven't done a search, but is there an information source that states exactly what Samsung did to address the LOS issue?
I'm going to ODIN back to the original shipped EG30 package and test it out.. I never did OTA updates.. always through ODIN, etc. I'm going to see if I update through OTAs if anything is different. I'll report back.
I had experienced it since around the 1st week of october. i didnt have los fixed until i flashed chris41g's experimental kernels, not sure when all that was though. i was convinced it was related to signal too, but i would still happen on the highway/in public with 3 bars of 4g and ~50-60 dBm
would be interesting if you figure it out though
Yea I ODIN'd back to EG30 and now OTA'd to EL29.. no issues yet but we'll see tomorrow when I'm in elevators. After doing all this, I realized I probably need to do a full EEPROM reset and then go through this... don't really feel like doing that tonight though.
Im pretty sure this is in fact a samsung phone issue in general. I came over to sprint and the e4gt from verizon and the fascinate. I loved that phone, but it had this exact same issue. I have not in fact had it happen to me so far with the e4gt yet. I have a sneaking suspiscion that this issue goes hand in hand with undervolting, but thats just my own personaly theory.

Happens to me on the rare occasion as well. Might be an issue with the phone?
I called this one during the LOS era. It definitely occurs in low signal areas. I could never get LOS so I went into known dead spots and sure enough those random pop ups happened

I noticed there were a few other threads on Samsung devices with issues.... hmmm. Did you ever try limiting your underclocking to a higher clock speed? This may be a noob question but for the EG4T, is anything less than 800mhz considered underclocking?

I believe I remember seeing your post haha... I'll see what I can do if I mess around with clock speed.
I recently moved in to a new apartment for college and unfortunately my signal is very poor while inside the building.
This is really the only place on campus that I don't get great signal unless I get close to the window and pray that my phone decides to connect.
I've briefly looked into possible solutions but wanted to see if anyone had any suggestions/opinions on what I should/ could do.
I briefly looked into the Sprint AIRAVE, which I should be able to get. However, unless I can get it for free then I really don't see it as a viable solution, especially since my contract is up soon and I can just move to another carrier.
At this point I see my options being:
1. Get the AIRAVE.
2. Purchase a 3RD party signal booster (If cheaper than Sprint one).
3. Come up with some kind of DIY solution
4. Change some things on my phone in the hope that it improves.
5. Switch to another carrier.
What do you guys suggest doing/ think is the best option?
Are there ay other options I've missed?
Current Setup on my Epic 4g:
Rom: CM9 STABLE build from 8/10
Kernal: Shadow v0.6.3.3
PRL: FC09
I suggest option #1: Call Sprint and throw a fit, and have them provide you an airave
You may be better off with option 5.
The Airave is more of a cop-out solution for Sprint and their craptastic network. However, if it works for you then by all means go with it.
I've been with them for over 10 years now and haven't seen much network improvement in my city in the last 5 years. There are big patches of dead and weak signal spots all over. Hell, I can step outside my office building and find a dead spot in one 5 foot span, then move out of that span and be in a 3-signal strength spot.
I'm waiting a bit longer to see if their network will improve in my area. Otherwise, I will most likely jump carriers.

My family has used them for about 10 years total, with a brief break when we lived in england. I've never really had any problems with getting signal where I needed it before now. But yeah, at this point they better make a good offer if they want me to stay with them.
So I called sprint, they wanted me to go through some troubleshooting stuff and ended up asking me if I was rooted.
I had a bunch of back and forth with him and he claimed that being rooted/not on stock caused my phone to show no "vital signs" and that even if I am using the proper PRL it doesn't matter. Everything he said sounded like a bunch of policy stuff and he never gave a clear explanation of why it mattered if I am rooted. Anyways he said I could restore to stock/factory settings and then he would call me back latter and we would troubleshoot stuff.
I am going to be doing the flowing:
1. Backup everything
2. Odin back to stock (non-rooted + update)
3. Go through the troubleshooting, even though I know it won't make a difference.
4. Hopefully get the AIRAVE for free.
5. Go back to my current setup.
I've also noticed that turning 4G on may actually make a difference in signal (Since there is 4G in atlanta).
Does anyone have in thoughts about this?
Am I wrong in saying that being rooted has NO effect on connectivity?

If you do anything with Sprint that involves troubleshooting, you should be on 100% stock. Also, never admit to rooting, even though there is that PDF from internal Sprint mail around these forums saying it's basically okay for customers to be rooted. It's way easier to just get back on stock and step through troubleshooting, than dealing with a script following CSR on the matter.
It takes an experienced flasher all of 3 minutes to get from stock back to previous setup or a new custom setup. So not a big deal.
Turning on 4G is an entirely different radio; hence you would have differing signal strengths from 4G to 3G.

Maybe try the nexus modem and see if that improves signal. Some people say it has and got rid of dropped calls. Samsung is notorious for making awful modems, but Google made the Nexus one, so it is better for me and most people who have tried it.
I know really shouldn't have admitted to being rooted but I think I kind of wanted to argue with him about it, just to see what kind of reasoning they give.
And yeah, flashing back to my previous setup shouldn't be too hard. I already know for a fact that going to stock won't solve the problem,
I'm still testing the 4G thing since I can't really confirm if it is actually boosting the signal or not.

@xboxfanj: I thought about trying that the other day. I have to be on a CM7 rom to use it, correct?

Now there is a patch for CM10 as well. Nothing yet on stock or CM9.
Yeah I noticed that. I tried switching to PA1.99 and using the nexus modem but it didn't have any kind of effect in my apartment.
So I odined back to stock fc09.
The Sprint rep called me back, I told him it didn't have an effect (because it didn't).
He agreed to send me the AIRAVE at no charge so I should hopefully have it in a week or so.
After I get it all setup I'll update this thread with details as to whether or not it actually solves the problem.
Now time to root my phone again...

Received the AIRAVE today. Took a little bit of fiddling to get it setup right.
I now get pretty consistent signal, generally 5 full bars, throughout my apartment.
My only real complaint is that it decreases my internet download speed from over 100Mb/s to around 40Mb/s.
The decrease is unavoidable since I have to use the AIRAVE router functionality in order to have it and my computer hooked up.
However it did seem to increase my upload speed by about 5Mb/s once I increased the limit it had set by default.
It also seems to causes me to receive texts twice but that may have just been a one off thing.
Overall it has solved the issue and since it was free I can't really complain.
The double text is an occasional thing and probably will never happen again. I hooked my airave to my router instead of the modem as suggested and it works just fine and does not interfere with my throughputs.

This is how I have mine set up and it works perfect.
Mine is setup so that the AIRAVE connects to the wall and then to my laptop (it's probably hooked to a router/modem somewhere but it's dorm internet so I have no control over that).
It would probably be faster if I hooked it through a separate router but I don't really want to spend the money on one, and would need a pretty decent one since my school has one of the top 10 fastest internet connections in the country (if I had to guess number 3, behind the pentagon and google fiber).
Hey guys, i just got my N7 last thursday and I noticed the sporatic touch issues. Cant click a link until i zoom in quite a bit, scrolling a page stops and starts as i drag my finger across the screen. Its pretty annoying.
I started looking into it and i see lots of people having these problems.
So, is there a definite answer?
Is this a software bug that can potentialy be fixed? Or is this a hardware issue?
I am debating on returning the tablet... Which sucks because other than the touch issues, its been running great.
Thanks guys.
No.
No definitive answer.
And don't expect one from Google/ASUS.
Sfhub has a fix that, if you work through the options, has over an 80% success rate. You'll need to unlock the N7 and follow his instructions exactly.
That leaves the balance of <20% which are most likely hardware.
Your choice. (Maybe) fix it yourself, or keep returning until you get a 'good' one.
Personally, if I still had the option, I'd keep returning it until I got a 'good' one. Let them choke on the defective ones. We're paying them for a working device. Why should we have to fix them?

IMO it is ultimately a hardware variance in almost all cases, but in some cases it can be compensated for in software.
Google acknowledged the issue months ago, issued a fix that fixed some units and broke others, but has since crawled back into a cave and have not said another word.

Yeah, thats what i've gathered from all the posts i've read over the past two days.
Thats why Im willing to try the software side of things first. I figured its worth a shot.
I think it's hardware, the severity depends on your touch firmware (which I suggest you experiment with) and your eye for details. Mine works fine for the most part, sometimes it doesn't realize I lifted my finger off the screen but it's not a deal breaker. I still think it's pretty unacceptable, after years of capacitive touchscreens, I expect them to be flawless by now.
I just got mine today and mine is having issues. I don't know if I should tinker with the software or just send it back. I definitely need to do something about it though, it's an absolute pain for me to use.
