I'm experiencing an unusual issue where my phone will have full bars and not have data, or some times just drop all bars and data for several minutes. Some times a reboot fixes it but not always; the data comes and goes as it pleases. The issue seems to be more persistent with data drops than signal. The areas in which I'm losing data connection I've always had a strong connection in the past.
My first thoughts was a software issue but now I'm not so sure. I'll explain what I've tried and hopefully someone has some ideas.
a) Clean install of Cyanogenmod 10.2, and 10.1. In the past I had no signal issues with either.
b) Flashed the latest radio i727UCMC1 (was already flashed but did it again to be sure).
c) Checked APN settings. The settings seemed fine but since the issue is intermittent I don't think this is the problem.
d) Scanned for available networks and tried several of them. This resulted in no service on all but one, which was the default.
I'm working on getting back to stock right now but I was hoping for some insight while I do so.
Thanks.
if it still happens on stock and you tried it a different location then some hw prob like the antenna connection or the modem chip is dying, search this forum for "antenna" as it could be helpful

Interesting, and yes it's still occurring on stock. I heard that AT&T is having issues but it's been a couple days now. If it is hardware I'd be surprised as the phone hasn't faced any devastating drops lately.

The wifi is turning off randomly as well. It isn't dropping signal, it's literally becoming disabled and then re-enabled again. Sounds like my radios are tweaked or the antenna is shot. Already tried flashing the radio though. I'm not sure how helpful trying to boost the signal will be given that wifi is dropping too.
i had the same problem after a emmc change, wound up changing the motherboard, not what u wanted to hear !!! sorry fixed it though.

I am having issues and wanted to see if anyone else has this problem. Verizon already sent me a new phone and I already have the same problem with it. They told me they will take up to 15 days to investigate the issue. I think its a software or possibly hardware issue, not a network issue.
I get data dropouts - NO 1X, 3G or 4G! Cant use GPS and any apps requiring data connection. It happens every so often and sometimes have to restart my phone.
1-Way audio calls - Person calls me or I call them, I can hear them talking but they can't hear me
Who else is having any of these issues, please choose a poll option from above and leave a comment if you wish.
I voted Rooted, Stock ROM no problems, but when I was Stock I also had no problems.
I am rooted with stock ROM and get the same dropouts as you. Restarting my phone seems to fix it and if that doesnt then pulling the battery out while the phone on does. Annoying that I have to do that but at least I get my data back.
I'm not rooted yet. I have experienced a few data drops. Toggling airplane mode works to get data back. Once, however, I toggled airplane, and the phone couldn't seem to disable the radio. Did a reboot to fix that.
I'm having data drops quite frequently and its becoming pretty annoying
I'm rooted with stock Rom I hope Verizon might be able to help
Stock, with data drops, but not how you describe. I voted before I read your post. My data problem is no 3G. I haven't been in a 4G area yet and if I'm not on wifi, there is no data connection.
Kjjb I'm also having the no 3g problem as well I started a thread about but I haven't gotten a response yet
Rooted, custom ROM and have occasional data drops. Annoying.

Couple of different temporary fixes described there.
I am going crazy here. All day yesterday constant drops in all data types. No bad phone calls, but only talked with a few people yesterday. Today my data drops continue non stop. Has happened 3-4 times already.
I am going to call VZW and *****. They said it would take up to 2 weeks to diagnose my problem. That puts me outside the return window and I already sold my dInc.
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.

HAve you tried falshing different 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.
This has been happening since the first day I got the One Plus One. I was hoping it was a software issue, but I am on the latest and still no fix has been implemented. It seems that I am not the only one with this issue, however there are many that do not have this problem at all.
There's a page on it: https://jira.cyanogenmod.org/browse/BACON-228
(Copied and pasted to OPO Support)
I don't know if there's something wrong with my phone but it's been happening from Day 1 and I'm fed up that no firmware has fixed anything. I began with Rogers in Canada, and for the most part it works but it would stop the upload/download on the top right for a bit then start again. I switched to Wind Mobile and still does the same thing. I changed the SIM cards, did hard resets, etc, and still nothing will fix it. I have a feeling I have a defective chip because others have reported no issues. It does the same on LTE or 3G. I can never watch a full YouTube clip or anything. The issue happens when I roam as well.
I also did the *#*#4636*#*# and played with different modes but it did not fix the issue. I also have random bar jumps. This happens every few minutes so I literally browse for a minute, data stops for a minute, browse for a minute, data drops for a minute, etc.
I get exactly the same, in the UK on EE network. The data just seems to freeze for no reason, totally independent from signal strength etc.

I'm on Wind, and haven't noticed any issues, the speed is slow but that's a carrier-side issue since they only use 3g networks not 4g/lte. Um, there was another thread that had a couple different modems, perhaps you might see some success in stability by flashing those? It's either a issue with the modem, or the radio chip, but logcats would be helpful in determining and pinpointing the problems. (Just run the app catlog, and recreate your issue, then dump it and paste it to JIRA so the devs could have a better look, and as well as here, so perhaps someone could help/suggest something).
What's your current modem version?
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.

True.....
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.
Hello,
I have a problem with my OPO that has been going on for months now (I suspect it's hardware based? but not sure)
My opo can always connect to 2g network
My opo can only connect for a limited time to 3G/4G networks. If i change the network type, I get internet alright for about an hour or so. After some time or event (can't find a pattern), the phone is suddenly disconnected from mobile internet (even though data is ON), but my reception indicator is full. I also cannot place calls or get called: when I try calling, I get either a textbox "network unavailable" or the call attempt just ends on it's own without result. I'll call this state "fake 4g"
Here's what I have already tried:
-reboot, flash other rom, factory reset
-downgrade and upgrade TWRP back again
-messing around with 4636 (but i think i haven't tried switching to US band and back to EU - i'm from europe). Note: the interface shows precisely one cell tower when i'm connected to fake 4g
-going back full stock (flashing a version of cm prior to YOGPAS1N0) in order to update the radio. I even installed oxygen at some point
-pulling a logcat. However, this problem (other than the fact that i have only have a basic grasp of IT) is that I cannot exactly pinpoint WHEN fake 4g occurred without looking at the screen/placing a call. I managed to determine fake 4g came up between 4:55 and 5:46, which is still a heck of a logcat. In order to generate some logcat chatter, i've placed a few unsuccessful calls during fake 4g period (i've pinpointed those logs)
Does anyone have any idea as to the cause of this bug (not entirely sure it's hardware based because it works, well, sometimes...)? Or can anyone maybe tell me what to look for in that 50 minute logcat? I guess I can always have another logcat run in the weekend and check every 5 mins until i can spot fake 4g happening.
Note: I haven't opened it to check whether the antenna is plugged or anything (not that i would see much, i think). Anyway, i can always do it if need be.
Thanks in advance
I have been having a similar problem, the LTE range keeps fluctuating from zero to 3/4th to full from time to time, even when the phone is lying stable. Range appears well when on 3g. It isn't sim card based as iv'e tried various sim ,phone combinations.
Also i have noticed many topics appearing in the past few months regarding network issues ... some kind of a pattern ?
Ah yeah I forgot to mention that I tried the simswap trick too, to no avail.
So you're suggesting the hardware antenna might be of poor quality, that might be the case. If so, I suppose the antenna cannot be easily changed (ie incorporated in mobo or whatever).
Does anyone know whether antennae are prone to fail in general?

Nope.If there hasn't been anything that could damage the hardware,no.
Have you tried changing firmwares?
https://forum.xda-developers.com/oneplus-one/general/firmware-modem-oneplus-one-t3462214
Even i am facing the similar kind of problem and posted my question here https://forum.xda-developers.com/oneplus-one/help/internet-issues-intermittently-unable-t3714911. One more thing to note is if you try tethering with laptop the internet works just fine (it happens with my device) . Even i have tried many combination with 4636 interface but i really can't understand the reason behind it.
Flash latest modem firmware... Then *#*#4636#*#* ..then on phone change signal to 3g only or LTE only..
Helped me from losing signal
