LOS update -- new development

I am currently tethering over a 4g connection, and my internet is working fine, BUT I have a complete LOS for the cell signal. I think this could be a very important fact because we should be able to know some things by the fact that WiMax is working while the cell signal is altogether lost.
Hopefully, with this info, a solution is a little closer at hand.

Ok...when people say LOS do they mean Loss Of Service? Or Loss Of Signal?
Because if its the latter, that sht aint that bad. But if its the former...I'm glad I don't have it.

It is bad. People that get it have to reboot phone for it to come back and it kills battery life. Nit to mention missed calls and texts. It is a complete loss of service.

Its 2 separate radios..

I had pandora going over 4g earlier for hours...but lost signal with a crossed out circle after about an hour. Pandora kept going but u couldn't make a phone call, ths.falls in line with the other poster. Im running eg30plus over latest 2.1 midnight.

As WhiteWidows stated, it's 2 different radios. The LOS people have posted over and over about is the ability to make/receive calls (which is what the OP posted about). The Wimax radio (4G) doesn't transmit phone calls. That's why you can do data on 4G and still make a call at the same time.
.....

Hi guys, this is one of my first posts but I've been a long time reader coming from the Evo 4G forums. I'm rooter using Zedomax v3 and experienced multiple LOS as well.
Last night I tried limiting the clock speed to 1ghz and setting the min at 400mhz. Strangly I now get slightly better reception and never had a LOS yet. Will continue to test out this theory and see if it's clock speed related.
I came about testing this since I ran mine at 1.6 for a while and not only would I get more LOS occurances, I would also get phone freezes lol. I tether and stream music a lot so wanted to keep it slightly underclocked to keep the temps down. Hope this helps as a temporary band aid for the LOS bug

It definitely makes sense that the two radios are separate...the point of my post was just to offer some more information to help figure out a fix.
If one radio fails while the other stays working, do we know that the problem is phone-related? Many posters have speculated that the issue may be on Sprint's end, so I wasn't sure if this info did anything to challenge or support that theory. Maybe it does nothing, though -- just throwing it out there!

Someone posted a log cat of a LOS. There's still some coding in the radio files that thinks there is a sim card. Says sim disconnected and result radio off

Hopefully a solution is found soon, I've seen similar issues posted on various android forums. Androidforums, Sprint community and here. Wish I waited a bit to hear more user experiences....

Has anyone tried editing the build prop to manually change the preferred network from wcdma to CDMA auto? Maybe that'd fix that issue

I have been on my current SGS2 stock out of the box for over a week now and have not had any LOS issues, or missing texts, or data not working, or missing phone calls, etc.....
I have been using wi-fi, 4G, 3G, have an Airaive, went to an area where there is no Sprint service and phone roamed fine and then went back to Sprint service when available.
I have been unable to replicate the LOS issue on my current phone through all possible ways of using it.
My first SGS2 was also fine until I rooted it which then gave me an LOS within 12 hours of doing so.
If someone has a another sure way to get an LOS, I am willing to try it on my stock, never rooted phone but I don't think there are any other situations I can try that I haven't already......

Time.I have went 3 days without a los then 2 in same day.It is all random

LOS Strictly a hardware problem?

First of all let me point at that I am currently still a OG EVO user. This will probably be my next phone on DEC. 1 once I am due for a upgrade with Sprint. I really love the design and specs for this phone but I have been turned off by all the LOS talk.
If a phone can't maintain a working signal it isn't much good no matter how nice the screen or specs are.
After doing some research on what I hope will be my next phone, I've come to the conclusion that this is a hardware problem. From what I can gather these phones have some kind of defect with the internal antenna which is causing this problem.
This probably isn't news to anyone on these forums but I just wanted to get some confirmation on this. I'm hoping that if this is in fact that problem the next batch of these phones released around the holiday season will have this problem fixed.
Assuming this hardware problem is not fixed; is there any rom/kernel combination that is known to be most effective in terms of this LOS issue?

Na don't think it's a hardware issue, if so I believe it wouldn't be so random. With the LOStKernel I haven't had any more issues but others have. That being said, if it were a hardware issue i would've had los as well already.

I agree If this is Hardware issues that say the Antenna get low signal and then won't pick it back up. Then That Pickup is what needs to be fixed (and that is software). We've all had low signal or switched to Roaming. This is where the issue is, at least to me. The Low Signal strength maybe a 2nd issue but that may need a Power adjustment.
I also agree with the LOSKernel. I was averaging 1-2 a day and haven't had one in 3 days (I installed 3 days ago).

Interesting. I was assuming that this was a hardware issue but you guys seem to think otherwise. I could care less as long as there a way to get the damn phone to work. I really want this phone!!!

ditto on the LOStKernal.
i used to have LOS daily about 8 times. now i havent had it in a week and i flashed it in a week.

Yeah, it's not hardware. The way the bug pops up is extremely circumstantial...so much so that we still don't know the parameters of the circumstance that triggers the bug. Having a low signal seems to have something to do with it but it has also occurred with full signal...but software changes seem to have a gigantic impact on it. I haven't seen one in weeks. I dunno....
I wouldn't be too concerned. I have the phone and I'm not.
...and it is a pretty bad-ass phone. If you are already a Sprint subscriber you'll love it, especially coming from the Evo4G.

I have never had LOS.
Sent from my SPH-D710 using XDA App

I'm thinking this is definitely software related, I personally didn't have a LOS problem until I started flashing kernels.Even on the Loskernel I was experiencing several LOS a day, flashed back to stock rom/kernel and haven't had a problem. From what I have experienced, Los seems to correlate with the phone roaming off of the sprint network and unable to connect back.

Its software. I haven't had LOS since the day the phone came out.

Its a modem issue the kernel can only help so much. Samsung will be releasing a new modem.bin when they give us the maintenance update.

No it's a sprint problem my phone is fully flashed to ntelos and I have been trying to get los since monday even trying different kernels and roms I just cant produce los
Sent from my Galaxy S2 using Tapatalk

I've seen a couple posts saying the LoS issue is related to roaming off/on the Sprint network...this may be true to a certain extent but I sit 5 feet from an Airave and I'll get LoS a few times a day when at home. Happens just as often if not more when I'm out and about.
On a more related note, OP: this phone is great and they will fix the phone somehow or make good on it. If for some reason they haven't solved the problem and you are over the 14-30 days (maybe even waaaayyyy past that...months!) then they will take the phone back. If you can't get them to give you a free Photon or basically whatever you want, then you are a pushover! Just have to start making a papertrail for your issue, that is all really.

Would that necessarily rule out that the air wave itself is not roaming or losing/regaining signal throughout the day affecting your phone?

Its not a Sprint issue.
Its a Samsung issue.

I have an Airave in my house and do not have any connectivity issues at all to it. I am also using a phone that has not been rooted and have yet to get an LOS either.

My point is that if the air wave is losing connectivity at all, then your phone is as well forcing it to roam

I never got LOS until I started flashing(about 3 days )
I was getting once per day utill the Lost kernel came along, now I've only had 1 LOS in the 10 days or so since the kernel has been out. I definitely believe it's software or modem related.
Bad ass phone nonetheless...dont hesitate!

Love this phone. Got it launch day and have never experienced a single LOS. I've never tried to root it or install a custom kernel.

Stock rom and not rooted, never had LOS.

I only have had LOS when I installed a ROM a long time ago.. Have had no problems on stock rom, stock kernel, rooted

No Network Signal After Flash to 4.1 on Verizon Galaxy Nexus

I just updated to 4.1 and can't seem to get a network signal on any of the ROMs I have tried. Anyone else had this problem or found or know of a solution?
Thanks.

Was this an OTA uprade? If you did an manual upgrade, you should make a backup before going forward.

Are you sure you used the correct ROM? Cross-flashing between a Toro/Maguro/Toro+ will often have the phone but up but with the radios not working

did you check your apn?

I just bought this phone on Thursday and the bestbuy rep had the same problem on two different phones and had to call the Verizon help desk. She managed to get it working and of course my signal went in and out as soon as I left the parking lot. I went home and immediately rooted and flashed 4.1 and had the same issue. I was on the phone with tech support and they couldn't find the problem.
I then did a quick search online and found that this is a common issue. The problem is that when updating to 4.0.4 the galaxy nexus has a hard time with the 4g connection. It then drops to 3g and then it realizes 4g is available and switches back just to start this never ending cycle. This causes a signal to be held for seconds at a time before dropping completely until it switches to the other.
The temp fix is to disable LTE and run your phone on CDMA full time. This worked for me and I have constant signal everywhere. Eventually I know a patch will arrive so I'm content with 3g for the time being.
What puzzles me is how come this doesn't happen to everyone? Its a big enough issue that I found the solution within 3min of searching for a fix but not big enough for Verizon to be aware of.

I have the same issue. it burns your battery as well by switching back and forth. I used to leave my nexus uncharged at night and the sleep mode would allow it to only lose a a few percentages but now if i leave 4g on with 50 percent battery.. Its almost alway dead when I wake up

Sad to say I have the same experience
The story told by mclaughlin47 is almost exactly what happened with me. Even rooted and running BAMF Paradigm 2.1, I still have the same problem. If anyone knows of a way to fix this, please let us know.
I can't believe Verizon isn't aware of this problem. I actually had better battery life and signal with my Thunderbolt running Vicious ROM. I may just be returning mine if I don't hear of a solution soon.
Thanks for any help, cause this is ridiculous!

I am rooted now, but even on stock ICS I was getting a problem where my radios just die. Requires a reboot to fix. But when I was seeing it, they always looked fine. You don't know they died until you try to use data or make a call.

Do you still have your imei

I saw the same issue with ics and jb roms. Tried several radios but always dropped data and voice when using 4g. From what I've been reading, it's a hardware defect.
Mine also works great and stays connected all the time when I leave it in cdma mode. Went back to my rezound since 3g mode there at least still let's me use data while talking on the phone. I like showering in as much radiation as I can

Reflash the radio and the cdma radio. Samsung and Verizon Wireless both claim that hardware defects are not known issues.
Which hardware revision do you have? (looks on the label on the back should be 11.11, 11.12, or 12.0.)

i have 12.01
will try reflashing the latest radios

Have the same exact issue...just upgraded to a jelly bean Rom and my data drops completely and I barely have a signal, did a super wipe (radio-rom-Gnapps)...and went to my old rom of ICS and I still have the same problem...but for the most part I barely have any type of signal and calls are dropping, called Verizon and they told me something about a switch, and that there is no problem in ur area....I just called last night, I'm gonna call back today...wish there was a solution ...also tried that 3G switch I just read earlier and I still have a poor signal

Any updates? I'm having the same problem

Hi,
I'm having the same issue. I've had my Nexus for about a month now and have had nothing but horrible signal issues, while my old Droid 2 gets fantastic signal.
I'm using the latest Bugless Beast 4.1.1 with the latest radios that were released today.
People have mentioned it being a hardware defect. I'm assuming I should just go back to stock ICS and go into Verizon and exchange it for a different Nexus?

It may very well be a hardware problem, but my thought was a SIM card problem for the reason that rebooting often does not solve the problem for me. I have a passcode on my SIM card, so if my phone doesn't ask me to enter the code then I can assume it doesn't see the card. This often happens when I encounter the loss of data problem and reboot, and I usually have to remove the SIM card and fiddle with it a bit and put it back in and then it reconnects.
So I went to the Verizon store to try and swap my SIM card and they wouldn't give me a new card, saying that it's a known software issue that Samsung has already attempted to fix twice and they are working on another OTA update. I obviously made a ruckus about how I'm paying for service I can't access and I want a different device, blah, blah, blah. Basically he was incredibly unhelpful.
I've been on ICS AOKP and recently switched over the CM10 JB and that's when the problems started for me, but I switched because some type of battery issue (it lasted about 3 hours for a few days) caused my phone to reset itself and erase everything so it seemed like a good time to upgrade. So I may have unique hardware issues going on but according to vzw it is software-based. I'm not sure if this is something that can/will be addressed in a new nightly if that's the case.

PEOPLE, IT'S NOT A HARDWARE PROBLEM! IT'S SIMPLY A RADIO.IMG PROBLEM! A LOT OF PEOPLE WHO IS ON ICS, BUT FLASHED LATEST RADIO ARE SUFFERING FROM THIS!
What you can do is just flash to a older radio image. Not that hard. Will this stop the OTA? Probably, but you can either flash the latest version back or just manually flash it.
Have a good day.

I got mine the first week of Aug at Best Buy. The first one I got had all the problems described above. Radios dropping out and dropping every call I made. I returned it the next day, and the sales guy told me he was 100% sure it wasn't the phone. I asked him to exchange the phone and the card because I couldn't use a phone that couldn't make calls. He did the exchange, and the second phone was actually worse. Most of the time, I could not even make a call. So, the next day I took that one back. They gave me a third one that worked great for a week, then I started getting a no SIM card error message. The phone would reboot and work again for about 3 hours, then repeat error message. I took the card out, wiped down all the contacts with a soft cloth, and I have had no problems since. Great reception, no dropped calls. Great phone. I don't know if it is hardware or software, but I would keep returning the phone until you get one that works!
Once again, what is the point of having a phone that can't make calls.

"Ghost Touch" Issues

Idk if some of you have heard about the "ghost touch" thing where sometimes when you turn on the screen it'd be like someone was pushing on some of your capacitive buttons and you wouldn't be able to touch or do anything on the screen. Turning off the screen for a couple seconds and turning it on again helps alleviate the problem for me.
How common of a problem is this? It seems that this never used to happen until ICS came around. Is it due to software or hardware like a bad digitizer? Is this something that I should be worried about hardware wise because I'm planning on hanging onto this phone for at least another 6 months and warranty's going to be up soon in a week or two. I'm using The Goodness ROM and agat's kernel if that matters at all. Any input is appreciated. Thanks.

After trying to figure out what nearby was causing the RF intererence so I could eliminate it, I found this thread which explains that the interference originates in the phones 3G radio, not the environment. I just recently started having this problem, and from reading that thread, I think I didn't notice it before only because I was using a kernel with a fix integrated. So if you are having this problem and don't want to do surgery on your phone, maybe try to find a kernel with the software patch.

This has been happening like crazy lately, ever since Hurricane Sandy and also since running the FK09 JB leak. The Sprint signal in my area went from bad to garbage since the hurricane, not sure if the JB leak is also adding to it or not.
It is so annoying I am tempted to actually buy a different phone even though I love the E4GT.

Agreed Sprint screwed NJ hard as AT&T and Verizon restored services within a week...
On a side note, AT&T's LTE was up and running within 48 hours...Dunno about Verizon cause most of my friends have iPhone's with them. But I was roaming on Verizon full bars the whole time. But guess what happened when I tried to make a call? "Welcome to Verizon, please have a phone card or credit card at handy to make a call". I have roaming under my plan and I would like to use it...especially not crapping out in emergencies.

Sprint may be working on towers. Ask someone else that has Sprint in your area if they have the same problem.
You can also try dialing ##72786#. This will reactivate your phone, update everything, and reboot a couple times.
