[Q] nexus 4 signal/radio problem - Nexus 4 Q&A, Help & Troubleshooting

Hello,
During the past couple of weeks my nexus has been losing its cell signal every few minutes. It's like clockwork. If I completely wipe the room and start from scratch, its fine, but after a few days it always starts to do it again. Has anybody ever seen this? It was doing this on paranoid android, so I decided to leave it and go back to aokp. No luck. Cache wipes do nothing, rebooting it is sometimes a temporary fix. I am not using a custom kernel, and I don't ever flash new radios!
Any ideas? Thanks!

I have similar problem: Signal failure if I charge him.

I had nearly the same issues with my N4! But I don't life in the USA! I'm from Germany...
Over the he last 3 weeks me and my girlfriend lost network signal every 3-5 minutes... First times I was also wondering if that's because of a new rom I flashed or if the baseband doesn't fit with some of my kernel/rom combinations.
After 3 days I recognized that my girlfriend got the also this kind of issues, but she on a galaxy nexus!
So I started searching the Internet if other people have the same problems (especially the same issues but not related the N4)!
So in our case the problem is Vodafone Germany. Vodafone is building a new lte/4G/umts infrastructure and because of this they are shut down some of their network antennas in my area! After switching my phone to a 2g connection most of the problems are gone... And my mobile network speed also! :-\
So try to switch to 2g and see if it's fix your situation!
I get some money back from my provider because of the problems!
But the most important thing is that my N4 is ok!

Same problem as Ümit only losing signal when charging the phone. Does anyone have a potential solution?

Losing reception

Hi
I have an unlocked g1 using a three sim in the UK.
I have only had it about 10 days, for the first 5 days or so it would switch to 2g quite a lot and not switch back, which was not too much of a problem.
But for the last 3 or 4 days it will completely lose connection up to 4 times a day, only way to fix is to restart or choose the 3 network again in the options.
I had the problem originally with the standard tmob rom and i have switched to the CyanogenMod yesterday and updated the latest radio again and it has just done it again.
it even does it if the phone is just sat on the desk.
Anyone else having similar probs?
cheers

Sudden Loss of Data on Nexus S

Hey guys,
This is actually my first post here but I do A LOT of reading on this forum.
I didn't quite find anything regarding my question (or at least a solid answer), however, so I've decided to post it up.
Has anyone else experienced a sudden loss of data from time to time out of nowhere?
I go from having Full Green 3G bars to grey bars out of the blue. I've heard the green bars is to let you know that you are connected to Google services but I am not able to access anything that uses data.
For instance, when I open up the browser, I receive an error telling me there is no network connection. When I open up anything else that uses a data connection, Market, News, etc, I receive the same error about there not being a connection.
This would make sense if I was moving and going in and out of service areas, but it happens when the phone is simply sitting on my desk and not moving at all. I usually use it to listen to Pandora while at work and have noticed that the songs cut in and out due to this sudden loss of a data connection.
I went from a Nexus One to the Nexus S and have never, not once, lost my full 3G bars in this same exact location. I personally believe its a software bug of some kind and have high hopes for it being fixed in the future. The N1 had similar issues when it first launched and Google / T-Mo were able to remedy that for the most part.
I am actually on my third Nexus S because the first two had some type of hardware issue; the first one's back button didn't work or light up and the second one had a blown ear speaker and would sound like a blown speaker in a car. As an early adopter, I expected this, so it didn't bother me in the least bit.
ALL of them did the same thing, so I know it is not just limited to my exact phone. This is definitely something with the Nexus S in general (or the current build of Gingerbread).
Can anyone shine some light on this situation? Thanks in advance and keep up the great work here guys!
---------------------------------------------------------------
UPDATE: Here are a few steps that I have taken in order to solve my sudden loss of data issue. I'm not guaranteeing this will work for you, but it has worked for me and a couple of users here on the forum.
Do the following:
Activate / Use the Sim Card that came with the phone (this is to ensure you are using the latest sim cards)
Make sure you have a 4G internet plan. (No t-zones, No web2go -- FULL internet only)
Call T-Mobile and have ask them to Reset your phone with their Towers
Here's a more technical explanation posted by Johoja:
1) Having network selection set to manual ( i.e selecting 302490 or TMOBILE) will result in No Service on a reboot. Solutions: - Have to cycle airplane mode to get it to pick up service (can be done with automatically tasker) - OR Use automatic network selection. (you can force wcdma only but that will reset the SMSC which is annoying if you go in and out of wind away/home areas and you want to roam.)
2) Being in a area with no service for extended periods of time 5+minutes(subway, basement, etc) will result in a dead baseband, meaning once you come into an area with service the phone will not reacquire signal, airplane mode will not work as the baseband is now crashed, cant maunally search for a network. Have to reboot to get signal. Solutions: -Use tasker to cycle airplane mode on and off when in no service areas i.e) search signal 4 minutes, airplane mode on 10 minutes. This will keep the baseband from crashing and possibly save battery. -Use NoBars to accomplish thesamething ( taskergivesyou a bitmore flexibilty of course but harder to use) http://www.appbrain.com/app/nobars-b...omdryer.nobars - Use airplane edit to avoid turning wifi/bt off when airplane mode is on. http://www.appbrain.com/app/airplane...kalti.airplane
3) WCDMA perferred does not work. - No solution
http://www.google.com/support/forum/p/Google+Mobile/thread?tid=747f398a6c1bb2b9&hl=en&start=40:
I read one users response on a different thread regarding something similar to the issue that I am having.
They said T-Mobile told them to get a newer sim card and that this may remedy the problem. In my case, this has been the only constant in the 3 phones that I have been through. I have had the same sim card for about 3 years or so now.
I will try activating the sim card that came in the box with T-Mo to see if this remedies the problem. Since I'm at work right now I will have to try when I get home later.
Does anyone think this will have any affect what-so-ever?
The galaxy s phones when first released, all variants, had issues of signal dropping from full to zero bars while sitting in one place. I remember because there were YouTube videos of it All over and it was shortly after the apple antenna issue.
Not sure if or how it was ever resolved. But it seems that Samsung may just have this type of radio baseband performance if we see all these individual units doing this. I don't know maybe others can respond.
I have the same issue as the OP. I travel to the same location weekly with NEXUS ONE, signal never drops in the T-MO Country here locally, and streaming CNET POD CAST never a hiccup, however, with the new NEXUS S, I would lose DATA Connection only, while the 3G will show full signal. I had to reboot the phone to get the DATA back.
is it the S issue or 2.3 issue?
food for though....
If you have T-zones or Web2go or Phones 1st web, you will have problems
I had the same problem too, now I fixed the problem. The thing was that had the wrong data plan on the NS, i had my old web plan from my hd2 which seems like different from the one for the NS. I restarted my phone after 5 mins off and now i have my internet working beautifly. A T-Mobile rep said that it was an error in the system that made the phone think that that was the right plan for the NS for a few. A glitch you may say, but all you have to do is put the right data plan that all, easy. Hope this helped and have a wonderful holidays everyone.

this is happening to me too, last night for a little while and today for about hte last 4 hours can't get connection back. i have full white bars, with 3g icon but can't access anything
So I activated the new sim card last night and I'm still having the same problem. Albeit it doesn't happen as frequent, but it still does it nonetheless.
I will call T-mo again to verify my plan. I am on a 1500 Minute Family Plan which includes unlimited data and messages. I will see if they need to tweak something and let you guys know if this remedies the problem.
Ok, it seems like the issue has been resolved after I spoke to T-Mobile earlier today.
The rep on the phone verified that the data plan I was on was in fact the correct one. He said he was going to reset the signal from the towers to my phone to see if this would resolve the issue. He asked me to turn my phone off for about 15 seconds after we hung up.
Since then, I haven't seen the problem arise again so my guess is that it somehow fixed whatever was going on.
I'll let you guys know if this changes and the problem occurs again.

What's with the CAPS? ?
On topic: i have a captivate and I can confirm that all galaxy S phones had droppend data. An official ota update fixes it so maybe you guys need to wait for something official. Isn't there a new firmware for the nexus S already? Try flashing that and see if you still have issues.

Doesn't every android phone from samsung have this problem?
I know the Moment has that problem, after 3 updates samsung called it quits, I still have to reboot mine 2 to 3 times a day for data lockups.
@timur525 Yea, I'm already on 2.3.1.
I manually updated the first hour it came out hoping that it would solve the issue. The problem was still there after the update.

I have exactly the same issue as the OP. Extremely annoying to reboot the phone every time it happens. One thing I have noticed is that my phone doesn't know its number. If I go to settings, about phone, the number says unknown.

That shouldn't affect anything. My number shows up in status.
I had this issue resolved a few months ago as the push-to-talk app Tikl requires this in order to use it.
I was having the problem even with my number showing up. Call T-Mobile and have them reset you with the towers like they did for me and see if that helps you too.

I posted about this same issue on wrong section of the forum. Ive had this issue ever since samsung vibrant. I have applanet installed on my phone and some of the app that i installed accessed my apn and totally changed my apn setting to "Sirious application disabled.epc.tmobile" or something like that so i wyped everthing off from the phone and so far i havent had the issue ever since yesterday. Also i had the locale and language setting to korean so im thinking that might be causing it also.

That's what I remember too. I think its just an issue with the radio Samsung uses in all their phones. Might not be a way to fix it if even their new phones like the nexus s still have this issue. They prob would have tweakdd it by now if they could.
Same problem here. Xmas eve on shift and I have a phone that had no connection whatsoever (not even phone capabilities) this may be the one thing that takes the phone back. (If it happens again)

Have you called T-Mobile to see if they can give you a reset to the towers?
I had this done yesterday afternoon and haven't had the problem again since.
Also, if you'really using an old sim, I would suggest activating the one the phone came with just to be on the safe side.
If that doesn't help you then I would at least wait until just before your return period ends to see if there will be an update to address the issue.

[Q] Serious Signal (3G/LTE) problem (keeps loosing signal)

some background info.
I ran stock room for 3 weeks, then one morning the signal kept dying on me. it would turn on for 2 minutes then loose signal again. and they it got so bad that i couldn't even make a phone call.
so i did following:
* Reinstall room (using the settings option, and factory reset)
(still same problem)
* change new simcard
(same problem)
* then finally i sent it into service.
It came back working with stock room of course)
work done when it was in service (just a hard reset with computer, tested OK)
it now worked fine for a week, then i rooted, and flashed a G-flex room.
still works fine for 5 days.
THEN today the same damn thing happens again.
the signal drops in and out every 5 seconds, the phone gets insanely hot, and the battery drains insanely fast.
what i'v tried so far.
*Whipe dalvik cache and fix permissions.
*flash new modems. (two modems)
still same problem.
I really REALLY don't want to send it back in for another 4 weeks at the service.
Do you guys have this problem? i tried looking on google for people with same issue but nothing that relates to my model number: D_802.
can you guys helps me out?
I have the ls980 variant and get horrible reception after root. Replaced the phone and all was perfect until I rooted. Went back to stock but issue persists. Going to try and reload SW again and see what happens.

[Q] Phone Reboots in Poor Signal Area

Hi everyone,
I've had this issue with my D800 for a while now. I've done a full clean install of CM12, following all the proper channels and install procedures.
I live in an area (central California) where I can have LTE one moment and Edge 100 feet later. So there's inconsistency everywhere I go.
When I am in an area with poor signal, my phone with freeze, and then reboot. It's quite annoying and happens approximately 5 times a day.
I put the phone in Airplane mode and try to get the phone to do it again, and it runs perfectly fine. Turn airplane mode off, it starts searching for a signal, then the reboot happens.
I used voltage control in many variations to slow the cpu down and still, it does it.
Does anyone here have any suggestions on what I should do to fix this problem? Has anyone else had this issue? Thanks!!!!
I've also run into this on the LG G2 running Blisspop 4.0 (based on CM).
I had the problem too, but it disappeared a time ago after the fix. Since then only one reboot... (I think 2 weeks ago or so like that)

Signal drops randomly (and frequently). Verizon.

I have a problem with my 6p where the signal just drops to nothing (Looking for service) and 3 or 4 seconds later it reconnects to a good LTE connection. The problem is not my connection as I live in a good area. I was rooted with xposed but for ****s and giggles I went back to complete stock and it is still happening.
I have reset the APN settings to no avail. Is this a thing that is known to this phone? Should I get a replacement? It started just recently it seems as I have had this phone since launch.
What sucks is, is that this phone is absolutely perfect (or was) and I dont want to get sent a phone with screen issues.
EDIT: I ended up getting an RMA and everything is hunky-dory.

What radio version are you on? You can flash a different version in fastboot and see if it helps.

Im on the newest one. Do I just extract it out of the 6.0 image file and just flash it over the top of the existing one?
I forgot to also mention that I tried getting a new SIM card from Verizon but that did not fix it either.

Yeah. Extract it and flash it over the top in fastboot.
Did you ever find a remedy for this problem? I'm having the same issues on t-mobile so its definitely not network or a similar related issue. Did flashing the radio from the 6.0.0 rom fix the issue? I already tried several different 6.0.1 radios and a radio from 7.0 but to no avail. I'm about to try it and if it doesn't work I'm getting rid of this phone.
I'm going to assume you mean you'll be on LTE for the longest time then all of a sudden signal completely drops then comes back on, but without the LTE signal showing near the bars, so you'll have to airplane mode, then switch mobile data on and off, then do a restart. If this is the case. That has been a documented CM13 issue for the longest time. I had the same issue with the HTC M8...

I am on LTE but as the OP said the signal randomly drops completely for 4-5 seconds them comes back LTE and all. I don't have to reboot or anything. This doesn't have to do with cm13 though, I've tried flashing back to full stock and I still have the problem there too.

I've managed to get a logcat at almost the exact time the signal drop happens, I had to put it in a Zip since the Txt document was too big for the thread. The drop happened in the last couple minutes. I'm hoping someone here with more experience than me can help me solve this issue. Thanks in advance.
