Random data/signal losses... Will custom Rom Fix? - Samsung Galaxy Nexus

Hey guys... as it says in the title, I am having issues with my G-nex randomly losing connection/signal but then coming back again. From what I have read, this is a common problem... anyone have any tips? Also wanting to know if I flash a custom ROM if that would possibly fix the problem. Thanks!

Not necessarily the ROM, but the radios. Try that.
There are a few 4.0.4 ROMs for the LTE GNex out now you could try as well if you want to go the ROM route.

Is this happening to you? (See attachment)
If so.. I've been trying multiple radios and multiple roms all day without any progress, this still happens. Would love it if someone has a solution to this... I'd have having to send in my phone again.
The signal issues seem to stop when the phone is awake though... :/ But I'm missing a lot of phone calls since my phone is "off" when people try to call me.

yeah, that's exactly what's happening... it does seem to happen more when the phone is off, but I think it still happens when it is on. it is so weird! I went into the verizon store, one of the reps said that he had just been having this issue today and that he put it into airplane mode and back off again and it seemed to fix the problem... I did it, and it seems to have helped, but that was only about 20 min ago lol. see if it helps you!

Hmm.. interesting. The problem here is that this started on March 24th... :/ But, still trying Airplane mode, even though I'm not optimistic..
I emailed my provider, asking them for info, but a friend of mine has been working beside me for the past few days, on the same network with the same phone, without problem. So I guess it's time to bring it in..

Thanks for the info! I may try to put the latest rom/radio on it and see if that helps... if not i'll un-root it and send it in I guess.

I'm having a similar issue with my GSM model, It started when my phone was updated to 4.0.4. Phone signal suddenly drops and comes back again in less than 10 seconds. Sometimes it happens with 1 minute intervals between signal losses, sometimes 5 or 20 minutes, it's very random. After noticing the issue thanks to "Light Flow" that blinks the notification light in white when there is a signal loss, I installed this app (https://play.google.com/store/apps/details?id=com.smartandroidapps.missedcall&hl=en) to track it properly. The results are very frightening, I'm about to do a full wipe in hopes that the issue will be gone :|
ps: like you guys, I did notice that it's very most likelly to happen while the screen is off. Actually, it has never happened while the screen was on.

Same here, post 4.0.4 update on my GSM GNex.

Found this explanation....

[Q] Phone not answering calls, dismisses/ignores when trying to answer

(Info: currently running Myn's Synergy with Godmode and the Chop Suey 0.7 kernel, at least I'm pretty sure that's the version.)
The title sums it up -- I can't answer phone calls from my phone. Whenever I get a call, I get my phone out of my pocket, and then move the little phone icon to the circle (sense 3.0 lock screen), and then the phone dismisses the call. Sometimes it does so before I even get to touch the phone icon.
It also takes far longer than usual before it will let me call back, like it's not responding. I can get into the phone application, then I hit the number to call them back, and nothing will happen for like 30-45 seconds, then it will finally call.
Anyone else experiencing this? Any suggestions on fixes?
It's happened on-and-off since I started using Gingerbread ROMs, but recently it's been far more regular. I haven't been able to actually answer a phone call in almost a week.
I've never seen an issue like this.
You may want to try re-flashing your ROM/Kernel.
After wiping everything, that usually clears up "odd" issues.
[Not to sound insulting] have you restarted your phone since this issue started?

I'm going to try flashing the non-Godmode Synergy ROM. It seems to be happening more on this one than on others in the past.

[Q] Network locks up on E4GT. Reboot required to restore

Anyone else having this problem? My E4GT's network randomly freezes. If I'm on a call and it happens it drops the call but I can't close out and end the call. If I don't notice it has frozen, I just won't get any calls or texts until I reboot. Data over wifi works fine. If it happens and I put it into airplane mode then off again I get the circle slash no network symbol. Nothing works besides a reboot. I'm running a stock kernel and stock rom on a rooted phone. Anyone figure this out yet? I came from an evo to a photon to this and the data speeds were horrendous on this phone compared to the other 2. With this issue the phone is almost unusable. I did an SCRTN reset on the phone and that took care of the data speeds. If I can get this resolved the phone will be great. Thanks.

Why am I not recieving wifi notifications when screen off......??/

Hi
For some reason, I'm not getting notifications of text messages when my screen is turned off. Neither the actual audio or the vibrating.
Edit: found out it's only on wifi. 3G works
I tried all kinds of different ROMs but nothing seems to work.
Only when I unlock my phone I get a bunch of stuff .
Thought maybe it had to do with a kernel or ROM or Juice Defender so tried with or without. Etc.
I am coming from a SGS2 haven't had this problem so maybe people know what to do. I am a SGN noob ))
Really need some helps .
Thanks a lot in advance.
This is an unfortunate bug with 4.0.4.
I, personally, don't experience it...but it is pretty widespread.
Screen off=no signal.
Ok.
I had no idea THAT was the bug. Thought it was that the signal was gone completely.
Thank you so much for answering.
Was just about to check for a radio that would fit my region.
Might flash the update then. Thanks.
Is it only related to 4.0.4 ??
I now switched to Foxhound a 4.0.3 ROM and having the same issue . It's driving me rather mad :-(
Same on stock 4.0.2
Try the latest release of 4.0.4 with the IMM76I kernel... if that doesn't do it, then we'll have to consider our options.
... and maybe give the UGLA4 radio a try as well for ****s and giggles assuming you're GSM.
Ok. I found out what's up. Been in the house a lot because of my new phone flashing etc etc.
Just now walked outside and bam got all the notifications.
So now got home and wifi was on.
No notifications when screen was off.....
turned off wifi and bam got all the messages.
So only when I'm on wifi nothing is happening.
Edit: tried the other modem. Ddidn't change anything.
I'm rather clueless what it could be.
Ok this is becoming a little monologue lol...
Anyways read somewhere that in wifi advanced settings you can turn on wifi always even when screen is off. Hoped that sovled the issue but nope....
Read other people have it so we need a some real help.

[SOLVED?] GSM freezing not recieving calls/sms / No radio wake / wrong clock

Well, for the moment ICS (any version) is making my phone unusable as a phone itself.
I saw some people complaining about the GSM hangups (including me), so if you let the phone sleep, you wont recieve any call. The caller will hear the same tones, as if you dont pick up the call. If you send an sms on a phone in such state, it will only appear after turning it on manually (often having duplicate SMS). When you turn the phone on - you wont even get a missed call, no signs of anything.
This problem is very hard to reproduce, it happens from time to time.
I've tried to flash any other ICS based rom on the phone - any has the same problem. The only rom i hadn't such issue is 2.3 stock/modified. But i want ICS!
Anyone have any thoughts, what can be causing this? I'm tired of this happening, people complain that the cant tell me something urgent, and i dont even know they wanted to.
UPD: There is a parial fix for this issue by Maruzko by installing an app that prevents deep sleep (but thats battery consuming offcourse).
I think that there should be some internal fix for this issue, only devs can help up with that.
UPD2: My opinion that problems that people have with clock not synced is somehow connected, coz when you turn on the phone in that state, you see the clock changing rapidly and stopping at wrong time, so changed title to include that also.
UPD3: There is an alternative way to fix the issue, but not much tested. Thanx to sideshow03.
Tests and reports are much appreciated.
Hey! I'm having the same issue as you. I'm surprised no one came up with a solution yet.

Yup, me too. Currently at miui based on pac rom, havent noticed the issue, but cant be sure its really gone, or just "lucky time" until reboot.
Sent from my SGH-I927 using xda app-developers app
I'm having the same issues on a couple roms but later on today I'll flash CM10.1 and see if it goes away...
Just did with cm10.1
im in the club

I have the same 'No response to a call' issue after flashing AT&T UCLJ3 rooted on a Rogers i927R Glide.
Essentially, after the Glide has been idle for a while, not sure how long, at least 30 mins I think,
there is no response from the Glide when calling it, and it goes to voice mail, but not straight away though.
I can hear a ringing tone from the phone I'm calling from, but the Glide just sits there in sleep mode.
Try several calls but the Glide does not wake up.
Haven't tried sending it an SMS when this has happens though.
If I then wake up the Glide manually, and then put it into standby again and call it, it responds as normal and starts ringing.
The thing is, it doesn't happen every time, sometimes the phone could be idle for 2 hours and still respond to a call, others times it doesn't after say 30mins on standby.
Hard to troubleshoot as its so intermittent.
This did not seem to happen on stock Rogers GB.

Should this thread be merged into this one ?

Yup, the threads are the same, but mine is older
Sad thing - cm and other jb roms higher than 4.0.4 have the issue aswell
Currently have the 312 min value with interactive governor - this does not help, some deep sleep problem not frequency related

It doesnt appear to be just a Glide problem with ICS from internet searching but there doesnt appear to be a solution anywhere.
I found a reference to using an App called Wake Lock which some have found may fix it but at the cost of some battery life.
https://play.google.com/store/apps/...t#?t=W251bGwsMSwxLDMsImV1LnRoZWRhcmtlbi53bCJd
Choose PARTIAL_WAKE_LOCK in the config apparantly.
Ive installed it but not activated it yet.
Still testing with WiFi sleep policy set to "Only when plugged in", where as previously I had it set to "Always".
Anyways, there are devices on ICS that do not have such issue. May this be connected only with the tegra2 platform? Even have no idea how is this issue called to search.. sleep of death? As i know, its the state, when device does not wake at all, even after pressing power. Not our case.

Good point, maybe it is to do with the Tegra 2 platform or the sub revision of this ICS 4.0.4.
Yes, 'sleep of death' seems something different, when ieven the power button does not wake it.
I think our issue is referred to as not coming out of 'deep sleep' when a call/sms is supposed to wake it up.
Yesterday I had WiFi sleep policy set to be on only when on charge.
So all day I was on 3G data not WiFI. I called the Glide intermittently through out the day and it always woke up.
Today going back to normal setting of WiFi Always on to stay connected to an access point when in sleep mode. Will see how that goes.
Next I'll try:
https://play.google.com/store/apps/...t#?t=W251bGwsMSwxLDEsImV1LnRoZWRhcmtlbi53bCJd
Choose PARTIAL_WAKE_LOCK in the config apparently.
I don't have any issues with that.. sounds like a sysctl or build.prop mod though.. that's all I have changed myself without the community here.. everything works well in ICS and I do run litekernel 1.1.1 which may also be a + for the no hang issue

I'm running CM10.1 and not having this issue.
I did notice something though.
Hypothesis: Each ICS leak came with a different baseband. So there is an I927UCLG9 baseband, a I927UCLH2 baseband, and a I927UCLJ3 baseband. UCLJ3 introduced some ABI change that the libsec-ril we're using in AOSP ROMs doesn't know how to handle (or it straight up just has a bug).
I currently have the I927UCLH2 baseband as I never flashed UCLJ3.
Could someone more wizardlike than me whip up some baseband-only Odin images for testing?

"Sleep of death" already has an established meaning. It means there's an intermittent whole-system freeze that only happens when the device is in standby, giving a "dead" appearance. It's been the bane of Kindle Fire developers for some time now.
I'd call this "no radio wake" personally.

Nice term, tottaly agree.
I just can say, that I have tested the lite rom, based on 4.0.4, that has a baseband chooser in aroma installer. I've tried running it with a baseband from 2.3.6 stock rom (that was my only hope), that did not give any difference, radio still did freeze Anyway, I cant be sure I did everything right that time, and your way of solving this must be tested.
Also, my thoughts are about some ATT frequency specific things, as I cant say everybody here is complaining (most are from North America, right?). May this be caused by using glide outside of US and Canada?

That's quite possible, as I'm on AT&T towers even though I don't have service through them (I'm with a prepaid MVNO) and I'm not having problems.

Question OnePlus 11 not ringing when receiving phone calls?

I am not entirely sure if I'm tripping, but I seem to be missing phone calls pretty damn often. I think I recall at one point I randomly grabbed my phone to have it by me and noticed that someone was calling me but it wasn't ringing at all, though the screen did light up. I made sure my settings do have have "Do Not Disturb" mode on. I have the CPH2451 and running stock with latest OTA A.10 update. After doing a brief Google search, I see that OnePlus has had issues in the past but those are from the OnePlus3 and OnePlusNord so I am not sure if that's still relevant in this day and age.
Anyone experiencing something similar or have any clues as to what might be going on?
Edited: Fat fingered the model #. Fixed.

This might be obvious to you, so just ignore if you know this.
When holding your phone in your hand like you're texting in portrait mode, there's a switch top right and on side of phone.
Adjust the switch so it's down.
Ive experienced this, even after swapping to 2449.
Seems theres a couple settings that revert on reboots for some odd reason.
Just go into the phone app settings, notifications and reset thr ring tone and all set after 2 times doing it ... annoying?? damn right!... but at least its fixable ....

That's so dumb... The more I use this phone, the more I get buyer's remorse.
I haven't restarted my phone since I got it I think but I'll try that and see if the issue persists. Thanks!
Edit: Any word if OnePlus is aware of this and plans on fixing it? If not, perhaps I should forward this to them.

don't know if they are aware. just to add to the weirdness of it... for me... after the second time, the setting sticks...
i have this problem with my 8 pro, the phone doesn't ring and i think it goes straight to VM? seems like something broke with one of the latest OP updates?
There's no such version as CPH2541.
And here it works perfectly. Factory reset and try again.
