Almost every rom I flash ends up having the same problem: I randomly lose signal. Not the crossed out icon, but rather just no bars. This happens while sitting still and there does not seem to be any pattern to it. Some roms it would happen overnight, others it happens during the day. Some roms I can toggle airplane mode on and off to fix it, while others I need to reboot. I always end up back on stock roms because the issue renders all custom roms unusable. Does anyone know what I can do?

Have you tried going stock and see if the issue arise?
Did you try to go 2G only and see if your signal holds?
It could be a bad 3G signal and your phone is dropping in/out to boost your signal. you could be between two towers and your phone jumps from one to another because of low signal. Could be a bad antenna if the problem persist under stock and 2G only. There are alot of things that can cause this issue and the phone itself can be the source. You have to factor out every possibility to narrow it down.

I'm switching to 2g only and we'll see if it holds. I'll know in a few hours.
I would be surprised if it has to do with towers, it isn't something that happens exclusively in low signal areas.
At work I have full HSUPA+ signal and it still happens, at home I barely get 3g signal and it happens there.
It happens at my girlfriend's house too and there is moderate to high HSUPA+ signal.
The problem DOES NOT persist with stock roms.
DOES NOT lose signal when data is disabled
******************UPDATE***************
even when locked to 2g only, it still loses signal.
Seems to be a hardware issue. I had the same problem on my last phone (a LG-VU) and I red-necked it and stuck a small piece of wire in the phone's antenna. It worked surprisingly and I had no problems with it for the remainer of my contract. But before going to those extremes, I would flash back to stock gingerbread, and try several different ROMs and Modems.

You might have a bad sim card. My phone was doing that last summer, and then one day I couldn't get a signal at all. Rebooting would fix it but only momentarily. I hit up an AT&T store on my lunch the next day and got my sim card swapped and lo and behold, no more problems. LOL I remember I was trying to hide my Cognition boot screen from the tech as my phone was still under warrenty at the time.
Every so often my M8 will basically become disconnected from the network. This NORMALLY appears when I'm in a low coverage zone, and it's as if my phone just doesn't want to reconnect when I get back into a higher coverage area.
For instance at my gym, I frequently get a weak signal, but it's usually 4G. Sometimes it'll drop to 3G, and then sometimes when I get back into an area of the gym that has 4G coverage my phone will say it's still on 3G. However, there's actually no connectivity at all, and I need to either reboot or toggle airplane mode to get a connection again.
Sometimes (at least 2-3 times in the last week) it happened while, at least to the best of my knowledge, I was in a 4G area (though with weak coverage) the entire time. Again I fixed it each time by toggling airplane.
Has anyone else seen an issue like this? It's frustrating as hell. And more importantly has anyone heard of a fix for this?

Yep, actually I had a thread about this a while back; I tried just about everything (other ROMs, new sim cards, factory resets, the whole shebang) and my only solution so far (if you intend on keeping your current phone) is to completely unroot my phone, along with removing all root-related applications (namely Xposed). It still happens from time to time, but a lot less frequently then when rooted and running Xposed modules. I have a new phone coming in today from Verizon, so hopefully that unit will not have any of these issues... I still am not entirely sure what causes it, though it is definitely exacerbated by Xposed. Hopefully some of this helps? If you have any further questions feel free to ask, either through PM or this here thread.

I have a new phone now, and so far I haven't experienced any data connectivity issues. This morning I did notice that my SMS were not sending properly, but that issue has since faded away, so hopefully it was Verizon network based... Anyways, I will try reinstalling Xposed and a couple modules later today (likely Snapshare and the Sense 6 Toolbox) and will report back sometime tomorrow or the next on how it goes. Fingers crossed...

Lol, so after installing Xposed, I suddenly started having issues maintaining a solid 4G connection; 3G works fine, just whenever I do manage to connect to 4G I am unable to use any data (says I am connected to the mobile network, but I do not get any upload or download data movement). Even after removing Xposed and all associated modules, I am still experiencing this problems. I am going in today/Monday to get a new SIM card (hopefully this is what is causing my issues) but goddamn I just cannot seem to catch a break in terms of my phones' data connection. If the above doesn't work I may have to send for another phone, though after having now received three replacements this entire process is getting a little irksome... I really do love this phone, but it seems as if it is my M8 is rejecting my love from every angle.
UPDATE: The new SIM didn't do anything, I still am having 4G issues, so another phone it is...
it's not just your phone....

a lot of feedback on the web across multiple carriers of the poor lte signal retention on this phone.....this is starting to sound like a hardware defect or a major "radio" software glitch.

I had the same problem with my new M8 when travelling from/to areas with low or no data coverage back to areas where I knew there was a LTE signal. Only toggling Airplane Mode would make the data reconnect. That problem was solved for me with a new sim card.
I also had very bad data connectivity at home in a major southern California city (best was -105 dBm) whereas I got up to -83 dBm in some rural town in Arizona.

Some of these problems may be connected to the new data service VZW is rolling out.
I would wait a few weeks before ditiching this phone. 'Cause it rocks!!!

it has nothing to do with the AWS rollout - i have a Verizon Galaxy S5 sitting right next to my M8 ---- guess what - consistent data speeds on the s5 (15 mbs down)......on the m8 (3-4mbs down) - and the data flucutates and in the signal meter , I'm getting about -6db less on the M8 than the s5.
trust me, i so desperately want to keep this phone, b/c quite frankly, i hate the amoled screen on the s5, but alas, i cant keep a phone that doesn't work well

yes - sorry bro - i'm quite disappointed by what i am seeing with my own two eyes as well as all the others across the US and the rest of the world who are experiencing the SAME symptoms. so this is not a verizon network issue --
me thinks its a faulty radio which is causing bad handoffs between 3g and 4g (LTE). once the phone drops down to 3g, it never regains 4g signal for some reason. also, there is the issue of the constant signal fluctuations even when the phone is on LTE...so who knows. maybe combo of bad radio and poor quality antenna module.
i'm not a phone engineer but i have enough common sense and knowledge about phones to know a lemon when i see one......so, yup, i'm keeping the s5 and return the m8 tomorrow under the 14 day guarantee from verizon. shame....

To tell the truth I have been reading about the same issue on the general M8 forum - probably just didn't want to make the connection.... So thanks for opening my eyes.
I'm hoping for bad radio software that may get fixed with some future update (although my 6th sense tells me it's the bad antenna module....)
Too late for me for a clean exchange. Gonna have to read the Squaretrade fine print.....
My phone is dropping cellular signal without warning. Cycling airplane mode or cellular network mode does not fix it. Only rebooting the phone has succeeded in getting signal back. This problem started last night. Since then, I have experienced it three times.
Further info:
I've had the phone for a little over a year. I did a factory reset when I installed L. I am running stock.
Any idea what's wrong and how to fix it?

Mine does it all the time on lollipop. I moved to a different state a few months back, where I was living in florida I didnt have the issue but when I moved across the country it started for me. I went to att after troubleshooting all I could and they informed me that they dont have a reliable lte network here...it exists but its weak and slow. So I set my cellular preference setting to 3g and since then it rarely disconnects or drops signal. When I go to an area that lte is good I switch it to lte and it holds fine till I get back home.
I just started playing with my wife's new idol 3 phone. everything is great so far with the exception of when wifi is turned on I noticed that cellular signal turns off and on sporadically. When wifi is off, the cellular signal never drops.
Updated!!!!!! ALCATEL THANKS!!!
The WiFi and Cellular signal issue is gone!! New update is great.
I have not noticed that. I leave my Wi-Fi on and connects when home without issue. I've check cell signal levels regularly on new phones. My first impression with this phone is that the cell reception is excellent.

I've noticed that a couple times as well. I assumed it was my SIM card as I changed carriers the same time I got this phone. It's not a deal breaker for me as I actually don't use the phone for calls much anyway. But yeah, it needs to be fixed. Just waiting for the next update.
Great, i thought maybe it was her phone in particular. I mean, I accepted the current update thinking that would solve the issue, but it didn't. Same story.....when wifi is on, the cellular signal turns off, on, off, on....maybe within 5 second intervals. Im shocked many people haven't complained about this.
if it wasn't for your response I was going to return the phone back to Amazon and exchange it for another one.
other than that I think the phone is excellent for the money and since my wife really isn't into development and rooting, for her this is the perfect replacement for her defective S4. however I would still like to be able to install a custom recovery at least.
My issue isn't anywhere near as bad as yours I would say. If yours is turning on and off a lot them you may want to replace it. I notice mine turns off once a day for a few seconds but I'm sure it does it more and I just don't see it.

I've used my phone to tether a few times and noticed the cell signal drops now and again....there is an app but I can't remember the name..something like "connection stabalizer" that toggles airplane mode on and off when it detects a dead connection....it might do the trick.
I have never experienced any of my previous phones do that, so i will most likely be sending it back for an exchange from Amazon.

I have never experienced this either. Have you tried a factory reset yet? I may try that in a couple of days and see what that does for me.
Well see, before i took the latest update the problem existed.........then, after the latest update the issue still exists. So i don't think a factory reset will do it but i will before i actually mail it out.
I reset the phopne and installed a mobile network detect app that notifies me when the signal drops. we'll see what happens.
I have no job so I have the time to blow
I am having the same problem. I am losing the signal repeatedly. It goes to no service then comes on to two or three bars even when I am in the exact same location.
So far so good. 6 hours later and no signal loss yet. On another note, the reset fixed an issue I forgot to mention. when downloading from the play store the download would start and immediately get stuck at 66kb. I would have to start and stop the download two to five times before the app actually downloaded. I just finished installing all my apps without an issue.

Borghi, so your WiFi is on when this occurs too huh?
I will lose signal when on WiFi with LTE enabled. Switch to WCDMA/GSM and it doesn't happen. Weird. Going to factory reset this weekend when my new SD card comes.

Wow so maybe this is a 100% Idol 3 manufacturing issue that demands for a recall.
Me returning the phone for another one is futile. I mean who doesn't want to keep their phone on LTE???
It might also just be a firmware issue.

It's been 28 hours and as care as I know I still have not have a dropped cell signal after the factory reset. If you have an issue will the cell radio try a factory reset first before returning it.

Mostly. Wi-Fi was off about 6 hours while I was sleeping. I'm using Network Signal Info Pro to tell me when I lose signal. I know it works cuz I turn on airplane mode and it notified me. I carry the phone around the house so I don't miss a notification. So far in 33 hours still no signal loss.
Have my Z5 since before christmas, was working very well till 7 days ago, suddenly dropped from H+ to Edge, then no network, and its been like that most of the time ever since, do a network search, sometimes it finds all the network, sometimes it finds only LTE, most of the time it cannot connect to a network. when I walk outside I can get a connection, but sometimes it cannot make calls, text or data with full signal on H+, for the last 7 days, if I walk outside by 5 feet away from the house I get a signal, walk another 40feet further I have no signal, walk another 30feet further I have a signal, while I have a Z and a s6 both working fine on H+ on the same network, swapping sims made no difference to the z5, and my sim works in all other phones perfect.
anyone experienced this?

How they are going to replace a phone with unlocked bootloader and with custom kernel?
Did you flash your phone with full firmware and full wipe?

I did, tried 5 different ftf full wipe everytime.
yea bad move for unlocking, certainly wouldn't go with my current provider again, regardless of unlocked bootloader, they have no intention of replacement.
I just checked the antennas they are fine, only thing I see different is with or without the grey antenna wire connected or not, it made no difference to the signal, sub antenna looks perfect and main antenna look perfect too. there's nothing to is just metal contacts.
if the fault is not the board then it be down to software, the phone works in area with good signal, in town and city I get 4g+ and download speed is great, but upload speed still poor, would it be the ic on the board?
PS. the Z5 is much easier to open than anything else I worked on before
maybe a silly question, but should I unlock the simlock first before I unlock the bootloader? this is my second z5, first z5, a week after bootloader unlocked, no network, no sim work in it, no TA backup but it does work in area with strong coverage, even on 4G+ with full signal
bit worry to do anything with the new one now
