[Nexus 4 Q&A, Help & Troubleshooting] shotta35:
This part makes no sense in that 3G is UMTS but besides that all phones drop back from HSDPA, HSPA and HSPA+ when data is not actively being used. The Nexus 4 in some areas wont fall back to UMTS ("3G") as it should like mine but by design it's supposed to. There goes your theory of experienced tech (look up videos about Fast Dormancy on XDA TV and you'll get an explanation).

I don't have trouble with this however and i'm using AT&T as well.
[Nexus 4 Q&A, Help & Troubleshooting] Hung0702:
Just so people know: I requested a replacement and the replacement hasn't shown any data drops.
[Nexus 4 Q&A, Help & Troubleshooting] imthekingbk:
I am very glad I found this thread as I am having similar issues. I was on T-Mobile with my Nexus 4 because the phone was constantly going from full bars of HSPA down to nothing and indicating I had no service. I thought this was a T-Mobile issue and moved over to straight talk where I am having similar issues. When using the device, every couple of minutes I will lose signal. I only lose signal for a few seconds but it is incredibly annoying and am not able to complete phone calls. I am wondering if this is a hardware issue because I am in a good T-Mobile and AT&T signal area according to maps.
[Nexus 4 Q&A, Help & Troubleshooting] surkins:
I have the same problem. At first I thought it was a Sim card issue, so I went to tmobile to get a new sim card. It was okay for a few hours, but then I started gettting the exclamation mark on status bar that said no network connection. I didn't get this on my Gal S2 (usually it gets 1-2 bars at home). Nexus 4 drops to zero bars.
[Nexus 4 Q&A, Help & Troubleshooting] s10shane:
I don't have any data issues on T-Mobile. I've had my phone for almost a month now.
[Nexus 4 Q&A, Help & Troubleshooting] :
My phone does this as well. Even on strong signal areas. It will go from 4 bars to 2, to 0 then drop for a second then come back.

Did this on both AT&T (Straight Talk) as well as T-Mobile.

Anyone have any luck with flashing a different kernel?

Or should I contact Google? I bought mine on the Play Store.

Thanks.
[Nexus 4 Q&A, Help & Troubleshooting] Dellair:
My girlfriend is having the same issue. (Belgium).

It's also impossible for her to complete calls.
[Nexus 4 Q&A, Help & Troubleshooting] frigidazzi:
Antenna is at the bottom of the phone. Try holding it on the top side when making calls. I agree it sucks it's this sensitive, but I don't think there's really anything we can do other than moving hands. We need an old school antenna in our phone that we can pull out for calls lol.
[Nexus 4 Q&A, Help & Troubleshooting] Dellair:
Anyone else that can confirm the problem disappears with using another kernel?
[Nexus 4 Q&A, Help & Troubleshooting] frigidazzi:
I've tried aokp kernel and Franco that I'm using now. No difference for me.

Did anyone try reflashing the radio using fastboot mode?
[Nexus 4 Q&A, Help & Troubleshooting] Dellair:
I've tried a lot of different things to get rid of the sudden signal loss and surprisingly I got it working.

But because I tried so many things it isn’t quite clear which attempt actually solved this issue.

One of the first things I did notice (except for the signal loss) was that the mobile network search did not return any results.

(Settings -> More… -> Mobile Networks -> Mobile Providers)

After trying a lot of things the sudden signal losses stopped.

I tried to do the network search again and with result.

The operators are now properly shown in the list while it was empty before (tried it on different locations).

One of the many things I tried was changing the ‘WCDMA preferred’ to ‘GSM only’ (dail *#*#4636#*#* -> go to Phone Information).

If ok, ‘GSM only’ should still be set after closing-opening the menu.

What I also tried after changing this:

-	Disable/Enable the radio from within the Phone Information screen

-	Disable the 2G only option (under Settings -> More… -> Mobile Networks

Note that this option got automatically enabled by setting the ‘GSM only’ option and that this option will be set back to ‘WCDMA preferred’ after doing this.

Some more things I tried:

-	Rebooting the phone (duh)

-	Enable/Disable ‘2G only’ once more

-	Resetting the APNs (Settings -> More… -> Mobile Networks -> Access Point Names -> menu -> Reset to default)

-	…

Things I did NOT try:

-	Wipe the phone

[Nexus 4 Q&A, Help & Troubleshooting] AlleN7:
I skimmed through the pages. But, last night I suddenly lost connection to T-Mobile. It had a terrible time trying to connect and get any signal. It wasn't dead all night so IDK what was going on. It randomly gave me 1 bar and POOF it was gone. The next morning I was fine. I've had the phones for 13 days so I hope I don't find out something is wrong with my phone after day 15.

BTW I was only handed a micro-sim, no tray opening device so I used a sharp needle to open it. You think I damaged anything?
[Nexus 4 Q&A, Help & Troubleshooting] hepatiit:
I'm in Estonia. I have similar issue, have tried different SIMs from different carriers, the problem remains. Phone is stock 4.2.2, no mods/no unlocks/no root. When phone is active, then signal remains, I am able to call out and receive calls, BTW, calls don't drop. When left untouched for approx 10minutes it is cut from carrier. It does show the coverage bars, but when called in, then states as out of coverage. When trying to place call it hangs in dialing display. When trying to end the hanged call, it hangs on ending call display. Only cure so far is to reboot, then i get next 10 minutes of service. Have restored to factory settings couple of times, tried without applying Google account. No luck. What to do? Sadly no RMA is availble, phone is bought from US eBay. F***!
[Nexus 4 Q&A, Help & Troubleshooting] wayneL84:
Hey guys, I was on r86 (if I remembered correctly) Franco kernel and used the Franco app to auto-flash to r97.

Everything is fine except I do not have any service (T-Mobile) anymore.

Was on AOKP 4 with Nova launcher.

I did a full wipe with factory reset and everything is stock now but still no service.

Re-seated sim. Rebooted few times also.

Sometimes it will show a bar or two, but when I try to call it just drops back down to nil.

It is not T-Mobile service itself, cause other cellphones in the home are fine

I've had this nexus since launch and never had reception issues before while flashing kernels and roms.

Any thoughts or suggestions?

I have the same problem in France with SFR network. It's really annoying and I don't have problem with my others phones.
[T-Mobile, Samsung Galaxy SIII] SomeAsianDude:
1. I made it so that it should show a bar that would let me change the brightness on the notifications tab. The thing you pull down with the time and your on/off toggles. (I have it turned on but it won't show anymore, I turning it off and rebooting and turning it on but it still won't show.)

2. Apps randomly crashing and it saying "Messenger has stopped working" or whatever.

And videos take forever to load, and sometimes when skipping it says "Gallery has stopped working", before I used LiquidSmooth the battery drained because of the Samsung stuff but now the battery is the same or a bit better but I have problems I didn't have before?

[T-Mobile, Samsung Galaxy SIII] jcbofkc:
PM the dev. Whining because you broke something in the Q&A forum is considered bad manners. Telling experienced users they do not know the rules is also frowned upon.

Try a different rom if the one you are using does not work for your needs. This is not a difficult concept. The are several flawless roms out there. Anything the deviant team (DJ or Evil) has out works great.

So would I lose everything again? I already wiped and flashed the rom. Not again but you know to root it and yeah.
[T-Mobile, Samsung Galaxy SIII] SomeAsianDude:
Back it up, I'm not whining about anything. I'm just asking a simple question. If you cannot be mannerly and kind about it, I suggest you don't bother posting on the thread. And if he/she knew the rules he/she wouldn't have posted his/her ignorant remark stating to post on the development thread. That surely doesn't show their experienced either.

You could've just said that. Simple as that. You didn't have to come onto this thread being a complete douche bag.

[T-Mobile, Samsung Galaxy SIII] SomeAsianDude:
I didn't say you were ignorant. Because that'd be spam posts. I didn't know where else to post because the rest of my question threads someone would come and just answer my question.

Hello guys! So, the problem is that the volume buttons on my desire don't work, so I can't go to recovery mode. Last time, I installed a rom, but idk what went wrong, and now I'm stuck in fastboot mode. I can't do anything else apart from going from HBoot to Fastboot, cuz the volume buttons don't work. This had happened to me before, and I think I solved it by adb, but now I can't remember how I did it, and can't find the thread I read it on. So please help me.

So yesterday i tried to flash a new kernel (nova kernel) using cwm and after attempting to reboot, all i felt was a vibration and then nothing happened. Is my xperia s bricked? and if so is there anything i can do?

What works:

1. Able to hold power button and feel the single vibration; however, the screen remains blank after that.

2. Able to soft reset and hard reset but it does nothing

3. Able to connect to pc in flash/fastboot mode

4. Able to flash kernels and firmware (flashed full stock .55 and wiped everything, still no progress)

What doesn't work:

1. Screen will not turn on no matter what i do

2. Phone will not charge (no led, no screen)

3. CANNOT ENTER CWM!

Any help is appreciated.

that could be it...but i doubt it because when i flashed the kernel it was about 98% battery and i haven't been able to turn on the phone since. that plus i've left the phone charging for 8 hours last night, which ended again with no led and no screen...

Maybe you should flash your xperia back to the stock ROM. You can do that using the official Sony flashtool: http://developer.sonymobile.com/201...ocked-xperia-smartphones-video-beta-download/ . Just watch the video and (hopefully) you will understand everything. After flashing back to stock ROM you can decide what you want to do with your phone afterwards :)

Hopefully this solves your problem!
