My device is lately having troubles at receiving mobile signal. It often loses it completely displaying the "no service" error.
Usually turning the airplane mode on and off works, and the device starts receiving signal again, but that's just temporary.
It generally shows no correspondence between the bars of the icon and the actual coverage and it might go from 4 bars to no service instantaneously.
The device is rooted, has the drm fix, SuperSU and busybox, but when this problem first appeared it just had the BL unlocked. I have the .224 stock rom, installed via FlashTool.
I controlled whether it was a SIM card problem, and it seems not; it first appeared when I was staying in a poor coverage area, so I thought that might have been the cause, but it's not, as I havr the same trouble (less often) even where I live. I have the general feeling that the device has become less capable of receiving signal, and that as soon as it is somewhat scarce, the phone completely loses it.
The idea I have is that my current firmware has troubles with my local network; I live in Rome, and my SIM is 3 ITA, therefore I chose the "customized IT" firmware among the 3 FlashTool displayed, which (from their names) seemed to be carrier branded firmwares.
Sorry for the long post, I've written everything I've thought might be useful.
Sucks I have the same problem, any solution?

You can try to install newest v253 generic firmware via flashtool.I dont have to to install specific Carrier Rom,that is not so important.
Install newest firmware and see what would happend.

Metal Bumper cases also are known to interfere with Signal reception, but as suggested try flashing a clean firmware ( preferrably Global release ) and see if the issue persists.
I get pretty bad reception most of the time and then pretty good reception where everyone else has none. My phone is very confusing!!
on the marshmallow is a very bad signal I am currently lollipop 32.0.A.6.152 is a little better but there is no comparison with my old Z1 signal great
nougat may be better for signal strength.
why see about that.
google translator sorry

Hi guys
I've tried researching this issue from time to time but have never been able to find any definitive information. A couple of threads around the traps detailing similar problems, but that's it. Anyway, what happens is this: the phone will be showing a couple of bars or whatever, but there actually isn't any signal at all. Calls can be initiated, but wont actually connect, and then can't be ended either. The only way to resolve the issue is to reboot the phone, or activate airplane mode and then deactivate it again (which tends to take considerably longer than a simple reboot). I'm calling it a radio crash because that's what it seems to be, but I could of course be wrong about what is actually going on under the hood.
This post is basically part of an effort to diagnose the problem before I decide what this phone's future will be (have a new, different model on the way now).
Thanks for reading, and any advice/information will be much appreciated
It sounds as if you have a defective phone, or it could be you carrier.
Have you tried a different phone.
Do other people have the same problem with that carrier
You could also think of it like this, carrier problem, you can connect to wifi if it doesnt have internet connection, it still can show full bars but nothing will load

I have an SGS3 now, with the same SIM in it (cut down to micro of course). Average signal strength (as reported by third party apps that don't pad) is about the same, but no dropouts at all (as monitored and reported by the No Signal Alert app). However the SGS3 supports both my carrier frequencies, and the Atrix 2 doesn't. Having said that, the SGS3 seems to stay on 2100MHz all the time anyway where I am.
I've also put a different SIM in my Atrix 2, from a network that is more compatible (850/2100), and although the dropouts are less frequent, they are still occurring. However, I haven't had a "radio driver crash" in over a week. The dropouts have only been momentary too, lasting no more than a few seconds, 1-3 times per day (mostly in the afternoon).
I'm also planning to charge the phone up and leave it at a couple of other locations for a day or two while continuing to monitor signal interruptions. Should be interesting.
Thanks for the reply
Just a quick update: left the phone at another location for a few days where the average signal strength is stronger, and not a single dropout was logged during that time. In certain areas this phone is obviously not as good as some others at maintaining a signal, but I don't think the dropouts themselves are indicative of a fault given this new information.
The previous instances of radio lockups/crashes are still haunting me a little, but this strange phenomenon is still yet to occur again. I also forgot to mention that I'd previously done a full restoration of the official 4.0.4 ICS release in order to return to the phone completely to stock, which might have something to do with that. Previously it was rooted, with only some minor modifications, but I guess it's not beyond the realm of possibility.
Wait i have an idea
Send me your apn data.
Motorola doesnt have the best antennas either.
Also does it crash at a certain time after it is turned on or is it random?

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 have this problem with my Z3. I commute to school by train and every now and then I lose signal because of tunnels etc. But the phone is having a hard time recovering signal. Sometimes I have to reboot. Sometimes theres the red X on the SIM icon but usally it's just that there's good signal strenght but no data connection. Other times a reboot doesn't solve it instantly and I'll just have to wait. Or I have to go and manually select my carrier (Tele 2, Sweden) but it doesn't work all the time either. So there's no consistent fix.
Anyone else experiencing the same problem? On my way home 2 stops before mine there's a tunnel where you always lose reception and sometimes I can't even recover it before I get of the train 10 minutes later in an area where you normally have full reception.
I've got a D6603, rooted .77 (PRFCreator). The problem started occuring before rooting. Can't remember if it was before updating to .77 (Had .77, downgraded for root then upgraded again). Carrier is Tele 2 in Sweden.

u need to repair ur firmware phone by PC Companion to install fresh stock rom
it means u will lose root access but u have to do this to realize if thr s software problem or faulty hardware.
:good:

I also have this issue, when I switch to CM12, the signal back. I don't know why my D5563 can't get data traffic from stock ROM :crying:
I have the same issue but with calls. If my signal is low and I try calling someone no one can hear me and it drops. I am on Telus, stock generic firmware. Going to try reinstalling it once the files finish redownloading.
i went to the service centre after a touch problem showed up on my phone and they told a software update is available and my phone was loaded with Cyanogen OS 12.0. But since it did not have any rooting capabilities, i went ahead and looked up some tutorials but could not find one and therefore ended up using king root. But now after some time i've realised that my phone has lost its signal strength, first sim (being of jio) almost never receives signal and though my second sim (airtel) shows signal strength, the person on the other side is not able to hear my voice(only some cracks and disturbance). The mic is working fine as i tested it on sound recorder.
So, i want to know is it a software problem that can be solved at home or i'll have to go to service center(which i would like to avoid as it's far away from my home)
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
