[Q] Different revisions of SPH-D710? - Samsung Epic 4G Touch

My brother bought his e4gt a couple months before I decided to pick mine up, and I felt almost immediately that he was getting more out of his phone than I was. I decided to run some head to head Speedtest.net runs. His phone is completely stock, and I have rooted mine but done little else to it. We're both on sprint.
In the WiFi test, I might have had a slight advantage on download speeds, but not a huge difference. 3G was also very close. 4G was a different story. His phone performed significantly better. The most interesting part was that his my phone seemed to struggle with both phones were side by side doing the 4G test, but still didn't perform as well when only one phone was tested at a time.
Looking over the phones the only difference I see is that his is marked. "11.09" under the batter compartment where mine is marked "11.11" and that his phone's batter was finished in Korea where mine was finished in China.
Does anyone know if there are actual changes between the revs of these phones, or did I just get the lower quality Chinese build? I know that people are getting lots of different results trying out different modems, has anyone correlated these results to the revision of the phone?
And finally, any tips on anything I can do to make sure it's not a settings issue on my phone? I've updated profiles and PRLs, anything else I should consider?
Lots of questions here, but thanks to anyone who can help answer them...

someone please help, my mind is cannibolizing itselfit

i've exchanged my first galaxy nexus today because i noticed that on really low brightness there were two streaks going down the screen. they were only visible when the brightness was low. i did have it on auto, which means that in dark places, this was the case a lot. anyway, i went to the store where i got the phone and they were really nice and exchanged it for me. big props to popular electronics. now, the screen seems fine. you could still see some streaking on super low brightness, but its definately much better. i would say to most people, even, not noticeable. i'm just anal, i guess. however, it now seems that the phone is a little slower/laggy. i mean some transitions between screens/menus is not as smooth as i think it was on the other phone. now, logically, the same phone running the same software, there's no way it could be different. however, it just seems like it. i don't know if it's just me at this point trying to find something or it's actually slower. i did factory reset twice, before entering all my info. someone, please tell me that's its just me or is actually possible for it to be laggy or for the software to work differently on this phone? almost everything else seems perfectly fine which is why i keep thinking it's just me. sometimes when you get something in your head, you start finding things your looking for.
by the way, i love this phone. have had all the nexus phones since nexus one and this one is by far the best.
Restore it. And chill out and smoke some pot.
i've also just did a speedtest.net test on this new phone and the speeds seem lower. last time i did speedtest on my other nexus, i saw about 10mbps, now the best i got was 7 mbps, most times around 5. could the same radio get a weaker signal this new one.

Unless you averaged dozens and dozens of speedtests then compared both devices in the same place at the same time of day you can't even come close to making a comparison like that.
For the record, I think you're just freaking out...
Yeah, its probably your brain getting the better of you. If you want, you could root your phone and try a custom rom if you wanted more speed? Maybe there was something you turned on in the settings unknowingly, or was already turned on (I have heard about something you can turn on in the settings called 2d gpu rendering or something which makes the performance better but causes compatibility issues with other apps) and don't smoke pot like the first guy suggested.

i think i'm just freaking out too. i just watched a bunch of youtube reviews and it seems those phones worked the same.
You're totally just freaking out
Relax - This phone is AWESOME!
alright guys. thanks for the replies. i'm going to leave it alone. the phone is awesome. i was pretty sure i was just being retarded about this whole thing.

2nd Nexus - reception still sucks

I burned through my extended battery in 2 1/2 hours today, and 4g drops were ridiculous. I finally called tech support, and they told me to exchange for a new one. So, I got my second one, still getting 4g drops. My wifes Thunderbolt (my old phone) holds 4g full strenght in my house all day. I am highly disappointed in this phone. If Rezound gets s-off by January 15, I may be switching. It sucks, because I really like this phone other than the signal.
Also, when I talked to tech support, she said there is an update coming in March, which I also read elsewhere on these forums. Why would they wait until March, seems kind of wierd.
I always read about people complaining about this phone. I have this to say to you:
If you don't like it get another phone.
I'm sure there are plenty or Rezounds out there for you.
Haven't you guys read that the LTE network has been on the fritz?

Cool story bro.
Sounds like an issue with the LTE tower near you. My reception has been great. I'm at 14 hours and I still have 19% left...barely had it 24 hours. If you have multiple phones wigging out, there are two possibilities:
1) The User
2) The Network
Let me guess, you restored all of your titanium backups and/or restored from Google Servers?
Here's another thought. Did you get a new 4G Sim card or did they just pop the old one into the new phone? Ta-Da.
Omg so many Verizon-noobs complaining, of course it has bad battery, it's LTE...
By the way i dont believe you in going from 100% to 0% in 2 and a half hours with two different batteries, unless you are dumb and has screen on 100% etc. If, however, you are serious, call Verizon or something.
Actually, half you guys are arrogant assholes. No, I installed everything fresh, my f*%$ing Titanium files wouldn't transfer from old Nexus back to my computer without hanging up. Yes, I have a high-end computer with no issues, yes the samsung drivers are installed, MTP sucks. Yes, I owned a TB since day one and never had 4g reception issues in my house. No, there are not tower issues, I know how to troubleshoot. I get 10mbs down on both this phone and the TB, except the TB doesn't lose its 4g signal. And yes, I got a new SIM card with my new Nexus.
Plus, I work downtown on the 33rd floor, and my TB held a 4g signal most anywhere in my office, even in the ****ter in the middle of the floor. My Nexus, burned through the battery twice in 8 hours and was in 3g half the day. But, I guess it's user error. It's clear as day there are issues with reception, it's just can you tolerate it.

No one said I burned through 2 batteries, I said I burned through an extended battery in 2 1/2 hours, screen is on auto, and you are an arrogant prick also. Do you assume everyone is dumb because they have issues with their phone? Also, I have been on 4g since day 1 with the Thunderbolt, I know where f##$ I get 4g and where I don't.
I had a little over 12hrs 36min with minimal usage in an area with known bad signal and had 21% left today, go figure i guess. Granted I only used my phone during my breaks and lunch. Still good for being connected to LTE all day imho. Im happy with the results I've had and I am totally realistic with battery life with an LTE phone, so much so i bought the extra battery+charger. If i happen to be in an area when I know I won't have the option to charge my phone, i swap the battery and have near full charge. It's awesome.
Software issue. Go cry to VZW please.
Yaaaaawn. User err... ogance.
Crazy world, ay?
You guys really are being dicks.
First off, it's clearly not the distance from the 4G tower because the thunderbolt is working just fine.
Second... the guy posts here saying he's had trouble with his second device. And being that an older device is working just fine he's looking for some answers. He's not trying to craptalk the device, but looking to see if anyone else has had the same trouble. That way in can gauge if he should attempt to get a third replacement, or swap out the phone for another device... or maybe someone figured out an issue with a specific ROM or discovered a radio that fixed his issue.
Instead he gets you Trollolols that are being complete dorks by telling him to switch to rezound or cry to VZW.
If you have nothing substantial or beneficial to say to his predicament, why is it so hard to just to stfu and move along?
Take that crap to androidforums.com where it belongs.
To the OP... have you attempted a different radio? Here's an article on it.

And you can try here to download some.

Gall0ws, thanks for the links, and support. I actually flashed the new radios on my last nexus, didn't get much of an improvement. The TB is between 75 - 85 dbm in my house, and the Nexus (including the new one), is typically between 95 - 115. I don't even care about the reading, because when I have 4g, it's fast. It's the drop outs to 3g that suck. Also, going to monitor this device for a few days before I flash the new radios, so I can really say if they made a difference. This just sucks, I was really hoping for an improvement over the Tbolt.
kwkslvr, I will take the screenshot, then punch it in your face. Do you think I am exaggerrating? Do you think I felt like taking all the **** off my phone, reflash everything back to stock and relock it, then waste an hour at Verizon, then reroot and put all my **** back on, I have no time for that. My thunderbolt is the original day one issue by the way, I don't exchange things for no reason. I don't use Titanium for anything other than restoring certain apps that I have that are no longer in market, no data.

I haven't had problems with my GN, but I did find these two articles interesting regarding the whole 4G problems w/ some GN owners. I'm sure it isn't any condolence but...
1.http://www.droid-life.com/2011/12/2...accurate-than-others-there-may-be-no-problem/
2.http://www.droid-life.com/2011/12/2...gnal-indicator-to-better-match-other-devices/
What I find most disturbing is VZW "fix" for this is to just change/ fake what the signal actually is at and they aren't stating if the GN is correct or incorrect?!?! lol
By the way, when I got approval from Tech to exchange my device, she said there was an update coming in March in regards to the signal display issues, seems odd they would wait til March for an update. Just repeating what she said, nothing more.
Here is a speedtest with my signal strength, speeds are fine, and I am reading 101 dbm.

The fix might not be simply falsifying any data but perhaps correcting an issue where the software is improperly calculating it. Which of course could lead to a lot of other issues such as excessive power drain because the phone thinks it needs to increase the power to the antenna instead of leaving it alone or reducing it.
For anyone having an issue with their signal, just keep a close eye on the radio threads. As soon as a new one gets leaked, they'll post it up and you can try it out.
And it can take a while, for example, my thunderbolt didn't have a good radio until on that was leaked Fall of this year. There is no rhyme or reason to it. some radios work better for some and not so good for others.
Obviously, if the phone isn't usable for his area, march is a long time to wait for an official update for verizon. But typically this stuff gets leaked out before an official push anyway.
Anywho, JC. Thanks for the links.
No major problems here
I've been running my phone for 2 days here without any significant battery issues; at least none more that I expected based on battery size and playing time. I've ordered the extended battery for insurance, but I fully expect that to do what I need. My only complaint at this point is signal strength vs. other VZ phones I've seen sitting right next to me. I have being disappointed here, am I alone?
Feel free to take a swing, but I don't think it'll fix your GN. I'll be awaiting the screen shot.
The AnandTech article is completely correct. I experienced a similar thing with my iPhone back in the day. This is a GOOGLE phone with as little Verizon interference as possible. Carriers want their users to think that they have GREAT reception everywhere they go. Those numbers are typically fudged, it's nothing new, I promise. As far as 4G drop off to 3G goes, most LTE phones suffer from this. Your T-Bolt is an older device. I'm sure you can't possibly have forgotten the number of LTE-related issues that device was plagued with early on. I remember a buddy of mine returning his because as cool as 4G was, 10% battery drain an hour on LTE while sleeping was just plain unacceptable. The Bionic has had issues. Most likely ALL VZW LTE phones are going to initially have issues the way that LTE and CDMA are basically taped together with very non-sticky painters tape.
I've seen connectivity issues with my MiFi related to specific locations that I'm in (I'm a heavy traveler with work). Any "fix" will be purely for display purposes. The day that release hits will be the day I'll be on XDA trying to research how block the update notification. The GN is currently displaying true and accurate reception strength and I'm sure it's driving Verizon up the friggin wall.
Ok, I'll stop giving everyone a hard time. But really, if the device sucks in your area, I'd return it and wait for a fix. In all seriousness, as you now confirmed from flashing modems, no modem is gonna make THAT big of a difference overall. Constructively, I'd wipe the device, log in with my Google Account, install zero apps, and see what it does. If my battery life sucked, I'd take it to the Verizon store and ask for a new battery. If that battery sucked (like draining dead 3 hours in sleep mode) I'd take the device back and exchange it.
It's not that I'm calling you a liar, it's that typically that kind of behavior is faulty hardware. Having it twice in a row is abnormal. In all fairness, my first iPhone had a bad battery and died in 2 hours (permanently). My second iPhone would overheat and lock up. My third iPhone was "fine" other than the fact that it was an iPhone.
Did it leave a bad taste in my mouth? Yeah, sure, but I still accept the fact that it was a weird chain of events and that the vast majority are perfectly fine. What I'm saying, nicely, is that both your first and your second device are not normal. It's not Google's, Verizon's or Samsung's fault...well, Samsung's for putting together a few bad units, but you know what I mean.
Haven't said 2nd device has bad battery life, just 4g drops. Hoping battery life will be better on this one.

I definitely think something is wrong with battery life. I bought the extended battery and my phone is at 20% in 4 hours with screen brightness at zero and light texting and a lil fb. I feel like the regular battery lasted longer than the extended one I might test that next.

Signal problems, what are my options?

As many, many other users of the galaxy nexus have reported, I am having some miserable signal problems. Obviously, CDMA nexus here.
I wish the issue was only that the signal on my phone is bad, but unfortunately it extends beyond that: my entire signal is lost at times. Usually it's intermittent and will happen 4 or 5 times a day for only 30 seconds at most at a time, but sometime (Usually late at night), it will lose its signal for even an hour or two, and I'll watch the battery plummet from as high as 54% to 0 as it searches for a signal the whole time.
I realize this is nothing new for some, but I almost feel like the problem went away for the whole world except for me, due to the low volume of threads related to the issue at all on the boards here. At least, recent ones.
What are my options? I don't really like the idea of trading in my nexus for a refurbished phone. Is 4.03 supposed to solve this problem? I had also read that rooting and flashing radios doesn't make much of a difference. To those of you with the CDMA nexus, what have you done to alleviate this problem? Or are you waiting patiently for an update?
Thank you in advance.
If bought new then return as faulty. Easiest solution.

The problem didn't go away. Most people had to make the decision to either live with it or trade it in on a RAZR or Rezound.

You could:
1. Trade it in for another GNex, on the "hopes" that yours is defective.
2. Trade it in for something else.
3. Live with it & wait it out on the hopes that someday Verizon will ship updated radios that will help. Current rumors say that could still be a couple of months away...
I am on the option 3 plan.
The leaked 4.0.3 radios have had limited & mixed results. For those who they do help, they don't seem to do a whole lot. There are a couple of people who had really good luck. Pretty much the same story for those of us who got Hardware version 10 phones - Haven't noticed any appreciable difference between it and the 9 I got on opening day.
Good luck!
strongergravity, thank you, that was extremely helpful; I was curious to how my fellow Nexus bretheren were dealing with the issue.
If a potential update can fix the radio, then I too will stick with number 3 as you have. Call me a masochist, but this thing is just too nice to part with.
Thank you very much for the detailed response.

I just saw your thread right after I created the exact same one today! I was just wondering what you ended up doing. No one has answered definitively as to whether or not this is happening on all phones. If an exchange will fix it, I would gladly go tomorrow. I know most phones are having trouble with the 3g/4g handoff but that is not the same issue we are having. What do you think!?
Mike
Same problems I've experienced. I'm on my second gnex, same issues.
Also I pulled speed tests next to other Verizon 4g phones (razor,rezound,TB) they all had significantly higher speeds than mine . I did multiple tests around our site, they had at least twice the speed as mine.
The razr pulled three times my speed most the time. 30+mb/s vs 10
The thunderbolt was around twice as fast downloads but uploads were even.
And the rezound was double on both uploads and downloads
I used the speed test app and speakeasy online.

Another comparison I did was turning on airplane mode on and off on all phones simultaneously. And switching 3g only on/off. To see which phones would latch on to 4g first.
Again the gnex was the slowest.
I really wish we received an update to fix this I love this phone!

I posted this earlier on another thread hoping it will get more views here.
So, I'm having the same exact problems but i did a log cat to see what might be culprit.
I have narrowed it down to this:
02-08 11:21:51.912 E/IMSFW (415): IIL: Disconnected from '7467' socket
still have no idea what can cause it yet.
also if you switch to 3g it seems it doesn't happen so maybe its a sim problem on verizons lte network end?
11:22:40.029 E/IMSFW (415): ImsSMSInterface: Registration failed, go for retrying if isim nounce present
that's what i found so if anyone can clarify and maybe see if it is really on Verizons end as this is the 4th phone that has had this problem
I will be going to verizon tomorrow to "try" and get a new 4g sim card and see if that helps somewhat.

I just went to the store and swapped out my 4g sim card... I dropped two calls on the way home from the store so I'm not sure it helped at all. Hopefully it didn't make it worse though!
I also checked my speeds and service against some other phones in the store and the Droid Razr destroyed my nexus and some other stock nexus that were there usually 12mpbs vs my 8 and 1mbps upload vs their 3.
Well I got my issues fixed today I was on tech support for an hour and he suggested to go to a store and get the sim card replaced. And that solved all my issues
Another problem I had was when using the headset for calling the person on the other line would here themselves. This has also gone away, I am so relieved I love this phone and did not want to abandone it.
Well, I did a bit of a test.
I kept my phone on 3g the whole day: Signal did not drop even for a single MOMENT in the entire day. Sure, there are times where it was bad, but my connection never entirely dropped. This leads me to believe that the problem lies with transitioning between 3g and 4g, or perhaps is just entirely related to 4g.
With the LTE network, I will have anywhere between 3% - 50% time with "no signal." It's extremely annoying and I'll always watch as my battery tanks extremely fast.
Maybe it's worth replacing the SIM card or at least, pulling it and putting it back in. Posting this here for others that are troubleshooting this same problem. I'll report back.

Signal issues. Requesting Quick Suggestions

I have seen around the forums a lot of talk about the radio for the galaxy nexus and the problems that they are causing. I recently bought a VERIZON galaxy nexus off of ebay, and upon activating it I probably lost signal 5 times over the course of the first hour I had it. I am not talking about low signal, I am talking about going from full bars to x (as if it is resetting the radio). It seems to happen almost every time i try to initiate a phone call or start to surf the internet. I have to try to call them, wait for my signal to disappear, and then wait for my signal to come back before I can make any kind of phone call. I saw posts about simply needing to flash new radio imgs to it so that is what I started doing. No combination of radios has fixed this thus far. Luckily it has a 14-day return policy.
My question is, has anyone out there with the verizon Baseband I515.10 been having similar problems, and found a proper combination or radio/kernel/rom that made all of this crazyness go away? Because I really love the phone to death (minus the battery life even with a 3800mah battery) but if i can't actually use my smart phone as a reliable phone then there is no point in keeping it.
Currently I am using FC05 and while it was better than the old 4.0.4 radio, it is still just not enough. Running Liquid ROM with Trinity Kernel.

[Q] Proper configuration...

Hey guys, I just bought a replacement Epic Touch 4G off of eBay after my old one ate itself.
I spent about 9 hours screwing around with the thing, and eventually was able to get voice and eventually 3G working. The MSL code was different from the one the (very frustrated) Sprint customer rep expected (only found this out afterward, using the getprop trick in the shell), which was interesting.
Anyway, I've been on an interesting journey with this thing. I'm completely comfortable with hard technical stuff, but the behind the scenes goings on behind cell phones is outside my usual domain. However, most of the kinks I was experiencing initially, seem to be smoothed out now.
But one thing is still killing me. My signal has been positively abysmal. I was having trouble updating the PRL the official way, so I learned how to use QPST to do it. At first, I threw a corporate PRL in there. No change. Then I changed to 25014 (the latest?), but still extremely poor performance. Additionally, most of the time, data is connecting at 1x. Once in a while I'll see 3G connect, but it's rare.
I'm looking for any suggestions on what to tweak, or -- better -- for a list of expected values for the #-code screens, so I can ensure they're correct. I'm not sure who had this phone originally, or what they did to it.
Much thanks, and if there's anything I can add to this to help, let me know!
