Random loss of connection?

It seems that during the last four days or so, I've had my One X lose network connectivity at random. I've tried going to airplane mode then back to regular and it doesn't seem to help. Next, I usually resort to restarting the phone and it usually fixes the connection problem. A couple times, I've had to restart the phone twice to regain connection.
Also, my locations have never been a place that does not have good signal. It seems like it's just a random drop off connection (texting and internet).
Anyone else have this problem?

Count me in. Has happened atleast 3 times in the past week. But airplane mode solved my issues
Sent from my HTC One X using XDA

Happened to me once. I could send and receive emails and use the web browser, but could not send or receive calls or texts. After trying to send texts and make calls for about 10 minutes, a restart resolved the problem (and revealed a few missed calls and texts).

Happened to me yesterday for the first time and again today. Airplane mode on off is working to restore it for me. It shows connection and signal but no data, texts or calls were allowed. I am in Minnesota so I am not on LTE its HSPA+ here. The areas it happened to me were in a town with a low population as well so I don't think that the AT&T towers are overloaded. I am hoping this is a software issue and not a hardware.

I have had the same problems randomly and yes the only way to get it working again is that I have to turn the phone off then on again. It is annoying me as it is happening when I play with the connectivity of the phone such as cutting off auto sync and mobile data connection.

I am having the same problem with my HTC One X. I thought it was because I am using a HSPA APN instead of LTE. In my case this happens constantly through the day. It's very annoying. I thought it could be a glitch with the stock ROM so I rooted my phone and installed a custom ROM and I still get the problem. I hope some one here comes up with a solution soon.

I was also having this issue the first week I had the phone, but I have since rooted, upgraded to 1.82, and installed CleanMOD (and ended up having to RUU a few times in that process) and haven't seen it happen again since. Not sure which of those steps fixed it, but seems like one of them did.

I'm having the same issue. I'm running CyanogenMod 10 on my HOX. For the most part no issue, but occassionally I loss signal (in good areas) but won't reconnect to mobile network, up until now I've just been rebooting, but may try to use airplane mode. Anyone come up with any solutions for this?

Try going into recovery, and wiping cache and Dalvik, then reboot. This has solved the problem for me every time I have frequent data drops. Sometimes comes back when I flash a new ROM. But then wiping cash & Dalvik again fixes it until the next ROM. Might not solve your particular case, but it certainly won't hurt anything.

Thanks, I was still having issues with a fresh install. I actually upgraded my radio this morning, thinking that might have been the culprit as I was on 1.82... flashed 2.20 do you know where I can find 2.23?

I used to have the same problem ALL of the time. Any time I went in to or out of an LTE or Wifi spot I would lose texting and data. I had called HTC about it a half dozen times. It was when I was using 1.85 though. Haven't really noticed it since using CR 4.5 and AT&T 2.20 radio.

Thank you, that is where I download the ATT 2.20, so are you running the ASIA 2.23? and will that work for ATT?

[Q] My phone is unable to catch signals after downtime.

So recently in our area cellular services are blocked from time to time due to security measures. Now the really annoying thing is that my phone does not automatically catch signals when the service is back and when I reboot they are back. I have tried switching back and forth from airplane mode but to no avail it just needs a reboot. Infact yesterday when the services were back my data connection started working but there were no signals in the status bar and I couldnt make a call.
What could be the problem? I am running rooted stock rom 4.1.2 with matrix kernel. Or is this possibly a problem with the cellular company?

What version nexus s do you have? What radio is running?

Its the i9023. Radio I dont know but I have never fiddled with this stuff so I suppose its stock radio. Only think I have done is root and custom kernel.

I used to have this problem, wanna know what happenned? My NS died (hard brick).
Most likely won't happen to yours.
The solution might be to flash a new radio that is compatible with the i9023. Radio's can alter your network performance and signal quality. If you're interested, here is a thread with different radio's:http://forum.xda-developers.com/showthread.php?t=1116884. Remember to always backup before flashing, and you can revert to your old radio by flashing it. To check your current radio, go to setting-->about phone, and look for baseband version.
An alternative is to try to flash a new rom, if you dont want to flash a radio.
Another alternative is a factory reset.
BUT, there is a possibility that our phones are designed like that, and none of these solutions will work.
Good luck! keep me updated

I have the KI1 radio. Well I asked a friend with an Iphone 4 and he says it "sometimes" happens with his phone as well so I suppose it's not something completely abnormal.
I don't actually have any signal problem apart from this issue. I never have to restart phone to get signals unless this specific timed ban on cellular services happen, I don't lose signals with some regular very short problem with network. I suppose it's just better to live with it than flashing new radios?
I might flash a custom rom soon so the factory reset solution will be tested then.
Did your Nexus S just randomly died? How do you suppose it had something to do with this problem?

I don't think it has to do with the problem, but i never found a solution because it died. Let me know how the new rom goes!

Btw there was also another problem that I didnt mention. Sometimes my phone refuses to turn on data connection and it only comes back with a reboot. This ONLY happens very rarely when I switch from wifi to data and never happens after data connection has started.
Did you have this problem? I just switched to CM10 yesterday and it has once happened so far but its not related to the ROM since it very rarely happened before as well.

I actually did have this problem! With my old ns. How long have you had this phone?

Its about 6 months old. I am experiencing this problem more whenever wifi is on for an extended period, so far I have had it 3 times with CM10.
I went back and forth to airplane mode and it started working so atleast didnt need to reboot.

I think this could be a 4.1.2 problem for me as I dont remember this happening previously.

Maybe try an ICS ROM?

Strange problems with Mobile Data and also with landscape...what can i do?

Hi guys,
i write because i don't know what to do.
I have two strange problems on my Nexus 5, the first (less important) is that when i put the phone in landscape it starts to lag, but after a few seconds it works fine...this problem is less important because a reboot ever fix the problem...but what can be the cause?
The second problem that is bad and it is that i have issues with my mobile data...when i tried to use internet it is really slow and it doesn't work fine...in first place i thought to some network problems but people with Nexus 5 and also other phones told me that they haven't any problem with the same carrier.
Then i clean flash a new rom (Carbon Rom) and i noticed that the problem was gone..however after some strange reboot in calls i decided to revert to stock rom (again with clean flash) and the problem with network is here again! Is a baseband (modem) issue? Maybe the Carbon Rom uses a different baseband?
I tried also to disable Xposed (that i use on stock rom and that there isn't in Carbon) but the problem is still here!
Of course i installed the same apps on Carbon and on Stock then i was in the same conditions. I used franco kernel (both on stock and Carbon) and changing kernel is the unique thing that i didn't make but i think it's useless!
What are your advices? Thanks in advance!

Well thanks for answer! It's nice to see that i'm not the only one! However (at least in my case) is really strange...because i have friends with the same configuration (Nexus 5 and same carrier) and all work fine! But it's also strange that if i try another rom and i leave in the same condition of the stock the custom rom work while the stock not!
When i will come home tonight i will try to flash another modem...maybe is this the problem!

Changing your modem will have an effect on your reception, not necessarily your speeds. That's usually determined by your carrier - you might want to make sure you're using the correct APN they specify. You can get them on their website. Also it could be the sim card you're using, whether or not it's LTE-compatible, or it could be the area you're in that's causing your speed troubles trouble.
As you can see, there's really no one way to fi things like this... you sort of have to troubleshoot it yourself, unfortunately.
Regarding Carbon rom, it won't change your modem - that's something you'll have to manually flash.

First of all thanks for answer! Well is not necessarily slow.. It's like a connection drop.. And like you can see is not a problem in my area with my carrier but something that only I have.. There is the lte in my area but I haven't a plan with lte connection then I set my phone in a way that he didn't search for lte! I will try the modem and if it won't work I will switch on a custom rom.. The strange thing is also that with carbon I haven't any trouble but with stock yes..

Mobile Data Connection Dropping

I have installed ViperOne and Clean Rom and I have the same problem with both. After a while of inactivity my data will just quit working. The icon will still be there but the phone won't connect at all. I have to place it into airplane mode to fix this. And just fyi sleep mode is off and power saver is off. It's just like my phone forgets how to connect after a little while. I had ZERO problems when I was stock. And now this.....please help me!

Oh and I have also done factory resets between each Rom install so everything was clean when it was flashed.

I can't wait to try it because I have the same issue on my travels but will have to wait until I get home and to my PC. Would love to read more success stories...
In essence santod says: flash the stock recovery, do a factory reset from hboot to restore the VZW radios, then restore your setup. Should work with most sense roms, but so far the people solving this issue all flashed a RUU.
Anybody have a link handy for the stock recovery?

Stock Recovery: Link :good:
You can find that and my firmware links in this thread.

Did the stock recovery so far so good but I won't know for sure until I get out and about today. It seems I didn't have the issue until it dropped from 4g to 3g back to 4g and have a decent 4g signal at home.

For now it seems as though that did the trick. I didn't loose data all day, we will see though.

Well it didn't work, I had to toggle airplane mode several times today to get data to work again.

That's what I plan to do tomorrow. It's getting to be extremely annoying. Not even toggling airplane mode or mobile data on/off does anything. I have to reboot every time.

RUU'd, stock recovery, flashed radios, and new SIM. I've tried everything. It seems as though if I'm in a low signal area where I go from 4g to 3g to Wi-Fi it happens. It's like there's a handoff problem between all the radios. Will show 4 bars of 4g but under mobile data in settings says disconnected.

Mine just started doing this. I'll RUU when I get back home to Texas.

I can confirm that it did fixed the issue, I didn't loose data all day no matter if wifi, 4g,3g, or 1x,

Same here. In the last 5 days I travelled in 3 states, large cities and very rural areas where it dropped to 3G or 1x - it never had problems to return to 4G (or getting a data connection at all).
This fix proves what's so great about these forums! I probably would have ditched a phone I totally love in all other aspects due to a problem that OEM customer service would not even acknowledge existed!

[Q] Data once lost wont re-connect

i am currently using Resurrection Remix 5.0.2 but was using cm12 nightlys before. The problem is that
the data connection is good but once i loose the connection there is an exclamation mark next to the
signal bar so i presume thats the data lost. It then wont connect again untill i reboot the phone.I have tried
switching on and off data but still no joy..This never happened on kitkat. I thought the problem was CM
related hence why i tried the RR rom but exactly the same is happening. Someone sugested that it could be
the sim card but im not so sure as it works fine before lollipop.I surely can't be the only one experiencing
this? but by the same token i can't find any info on it either ..maybe says something!!
Hope someone can help as i want to stay on lollipop i do like it, maybe the official release will sort it out.
Thank you

It's a ROM issue (radio.img). I was facing same problem on earlier builds of BlissPop ROM, but not no issues..
If you are getting exclamation mark in 2 or more ROMs, then there is problem with your sim-card or the network operator.
I suggest you to contact your concerned network operator and take his help for the same. (If you are facing same issue on 2 or more ROMs, try out Stock ROM CM11s)

Thank you for your reply, so would it be possible to flash a modem from kitkat or would there be compatibility issues with that?

did you check your network type and apn settings

So here is the latest update. I replaced the sim card on Saturday, the problem is is still there. I checked me APN settings they are three UK so that's ok. I've tried cm12,resurrection, blispop and now I'm on sabermod. I'm thinking this oneplus doesn't like lollipop, looks like I will have to revert to kitkat for just now until the official release comes out but I can't see that fixing the problem either as I don't seem to see anyone else with this problem.

I'm also with Three and have lost my data connection. They replaced the sim on Tuesday and I'm sure it worked until the old number swapped to the new sim. I have a 321 simcard on order and I'll try that once it arrives. My phone is still running Kitkat.

I had no problems with kitkat, if it lost the connection it automatically connected again when I was back in an area with a signal. But this has got me beat, a new sim card and too many roms to count but still the same problem. I am a lorry driver and cover the whole of Scotland and signal is patchy at best and it's annoying to find out later on in the day that data was off and you didn't receive any messages or emails.. Some of them important..

I have exactly the same problem.
I'm from Spain.
I've discovered that if i set network type to LTE it seems to work right.
Today I've moved from blisspop to temasek.
The 3g reconnect doesn't work, as always.
I turn data and wifi off when I sleep so tomorrow I will confirm if LTE works also with temasek.

my connection has always been set on LTE but never makes any difference
At the weekend I installed the official OxygenOs, I have been driving all day and had to reboot the phone 4 times because of this problem, I did half wish that when an official release came it would maybe sort out the problem but no joy. So I can only think it's to do with the oneplus. I'm at a loss now and seriously don't want to go back to kitkat but it looks like this will be the only solution to the problem..

I've tested this night again and if I set network to LTE.
The test I've done is.
- Turn off data and wifi before to sleep.
- Turn off only data when I woke up.
The connection was successful almost inmediately.

Greetings. I ran into similar issue with the CM12s update.
Once I lose the mobile signal for whatever reason, the data connection is not restored. Only way to regain it, is by restarting the phone (haven't tested airplane mode). Sometimes even if I leave WiFi on for long time (overnight), I will not have data connection after turning off the WiFi. I use HSPA connection only, not LTE.
I can not recall having this issue on KitKat. Issue was on the first CM12s update and remains on the second one, both were installed clean, so clean install of the ROM will not fix it. I am not using any custom ROMs or kernels, only TWRP recovery.
Has anyone had such issue and maybe found a solution to this?

Did you ever get this sorted? I've been having this issue, luckily I always have Wi-Fi at home/uni but there are times when it just won't find a Data connection. This happened right after the CM12 update :/

Well decided to a bit of searching, if you go into Settings -> Mobile Network Settings -> Network Operators and manually choose the network rather than the Auto Search option, it seems to have worked for me for the time being.

I am on the same boat as OP. The problems started after updating to Lollipop.
If anyone has found a solution, please let me know. I read about someone installing a 44S modem, but I'm unsure if this will permanently change system files (I wouldn't want it to) and I'm therefore hesitant.
