Phone loses mobile data after a few hours - Moto G5S Plus Questions & Answers

So this is something I've noticed happening on my Moto G5S Plus for a few months now. I was using Pixel Experience 10 without any issues up until mid-March, when I started seeing this issue. I would have perfectly good LTE and other mobile data when starting the phone, and usually I keep it on WiFi since I'm home most days given the current situation. However, when it's time to switch back to mobile data again after a few hours (for example, overnight), I would find that the status bar would indicate bars of service as expected but there would be no "LTE" or "H" or "3G" or "E" etc. indication there. Swiping down the quick settings shows "LTE" etc. as expected, but pulling up an example page in the browser then says "no internet". In this state, I'm able to send/receive calls and SMS, but unable to send/receive MMS and mobile data. It persists until I restart the phone, in which case the data works for a few hours before disappearing again.
Once I noticed this issue, I switched to Arrow OS and it worked well up until the April 25 build, at which point I once again encountered this issue. Since then, I've been bouncing around ROMs trying to find one that works for me and so far every single one I've tried (DerpFest, EvolutionX, Pixel Experience, Arrow OS) has this same issue - except POSP. My mobile data would work just fine for weeks on end on that ROM. Now I've been trying to move away from POSP because unfortunately it's incredibly laggy on my device, so I'm really trying to find the root cause of the issue. I'm fairly convinced that this is a software issue and not a hardware issue because it began happening at different times with different ROMs, and right after an update. Moreover, the issue doesn't happen at all right now with POSP.
The last builds I've tried are EvolutionX July 14 and Pixel Experience July 19, both of which have this issue still. Does anyone have any ideas on how to fix this?
Things I've tried so far:
- full wipe (including internal storage) and flash to stock via fastboot, then performing all OTA updates
- fiddling with my APN settings (matches what the carrier specifies on their website)
- checked to make sure that IMEI is still present (phone retains IMEI when I first boot it and have data, and it remains when no longer having data)

No 3G with CM 5.0.6

Today was the first time I installed a mod onto my device. I updated the radio to TheOfficial_Nexus1_Radio_Update_4.04.00.03_2.zip and flashed CM5.0.6. Everything has been great, EXCEPT my device won't connect to 3G coverage. It clearly displays 3G, but no internet applications will load (ie browser, email, weather). When I force the device to use only 2G / Edge, then it works fine, but obviously speeds are SLOW. WiFi too works flawlessly. Any ideas? I tried going back to TheOfficial_Nexus1_Radio_Update_4.03.00.21_2.zip and this did NOT solve the problem.
Ideas please? My N1 has become a 2G device in a matter of hours, SUCKS!
I should add I'm on T-Mobile and prior to any modifications today I had excellent 3G coverage.
For testing purposes...have you tried to flash 5.0.3 and seeing if your phone still has 3G issues?
I will try this right now. I was told it doesn't matter if I flash the radio before or after install... true?
No difference with 5.0.3. When 3G is displayed no data will transfer. When H is displayed, then I get good data transfer. However, the H is only there maybe 1 time every 5 minutes or so.
Could be an issue with not having rooted the device properly? When I rooted I never got the SU notification like I have seen in some threads showing a picture where you have to click "allow" for the device to allow root. I do have the app superuser permission on the device, but it's empty when I open it.
Thx
Well you can always just go from scratch. Get into bootloader, flash all of the stock PASSIMG images and then start over...
-flash recovery
-go into recovery, perform the traditional wipes
-flash the rom of choice
-reboot and see what happens
Does this happen in all locations or just at home/work/etc?
i've only been working out of home today. tomorrow ill be a better test. i took suggestions from posts i placed in the official cm5.0.6 thread in the rom development forum... and i changed some information in the build.prop. i think it has actually helped my issue... will be reporting back if i'm wrong..

Nexus One drops data signal, reboot required

Here's the situation: For about a month now I've been having issues with my data not working on my N1. Presently, I'm on Paranoid Android ROM, but have tried fixing the situation by flashing SpazeDawg, experiencing the same issue. My phone shows bars, and cycles between H, 3G, and E depending on where I am, but it's faded out, not blue; like it's not connecting. I do have voice and texting, however. I flashed the new Korean radio months and months ago, but I tried flashing back to 5.08.00.04, with no change in result. I've tried resetting the APNs to default, which after a reboot fixes the problem temporarily. I've run out of ideas on how to fix this, or isolate the problem. I'd rather not get rid of my N1, but the more I work on it, I'm beginning to think it is a hardware issue. Tried a new sim card, too! Any ideas on how to fix this? Thanks in advance.
I've been having similar problems ever since switching to ICS so I think it's just inherent. I've found that toggling data off and on again fixes the issue most of the time. So it's quicker solution than rebooting but still not ideal. Hopefully a fix appears but in the mean time I'm willing to live with it. For what it's worth, I've found Evervolv to be the most stable in terms of lost connection but YMMV...

Loosing randomly 3G or telephone signal

Hi all,
Since about 1 year i'm a happy owner of the Galaxy Note. As the stock rom was quite crappy (eating battery like crazy) I decided to swap it with a CM10.0 flavor (Cookies & Cream).
Well, installing the ROM went fine and the phone worked great, except one thing.
Since the beginning that i'm using custom roms on this phone, i'm randomly having issues with the telephone or 3G signal. As I thought, maybe the ROM is full of bugs, I wiped the phone and installed the official CM10.0 ROM. Unfortunately that solved not my problem. Since a couple weeks ago i updated to CM10.1, and still having this issue.
However, some issues where solved since the last upgrade:
- First ROM (CM10 flavor, Cookies & Cream): randomly dropping the signal, and asking for a SIM pin. Sometimes even a restart was needed
- Second ROM (Official CM10): same as above, but less issues with the SIM, mostly signal related
- Third ROM (Official CM10.1: SIM issue gone, however the phone is sill loosing the data signal + sometimes even the telephone signal (restart needed).
When I loose my signal, something it's just the data connection (3G/H). The strange thing is that most of the time that this happens the data connection or telephone signal restores when I enable/open the screen by using the side/home button. Well, that's very strange as I have no power saving apps or something like that running.
But unfortunately this is not always the solutions. Usually 1x per 2 days I have to reboot the phone in order to bring the signal for telephone + data back alive.
SIM has already been replaced, with no luck. I did install this ROM on another phone (from a friend) as well - which had in the beginning the same issues, however things seems to be become stable (haven't heard him anymore)
I already tried different modems on my phone (XXLSA / XXLSX, currently using XXLSO), but none of them solved this loosing data/telephone signal.
It starts to drive me crazy, as I use this phone for my work too.... being unreachable is quite annoying
Anyone an idea what goes wrong here, or how I can find out why this phone is going nuts?
Nobody that could explain why my phone is having this behavior?

Ongoing 3G issues with Galaxy S3 mini

Hello guys,
For the past year or so I am having intermittent problems with my 3g connection. It just loses the connection with the mobile internet without any error messages and the only way to fix this is rebooting the phone. At first it happened every couple months but the intervals between connection losses seems to get shorter. The last few months it was every 10-14 days, now it's every 5 days. Since a reboot seems to fix this I don't think there is a physical defect on my 3g chip but the shortening intervals are somewhat worrying. I checked my APN settings multiple times and I've called my carrier's tech support several times but they too can't seem to find anything wrong with my APN settings. I'm currently using a custom ROM (OmniROM based on Android 4.4.4 with the Stagefright patch included) but this problem existed even in the original ROM so I doubt it's a kernel/driver issue. Is there anyone knowledgeable enough to pinpoint the problem or at least help me in the right direction because it's becoming a bit annoying and I dislike not being able to figure out WHY something happens. ^^"
The issue you have mentioned applied also to my phone, but it appeared for the first time after installing Omni from golden-guy. I haven't observed it on my stock rom. At the very beginning, I was able to mitigate the issue by turning airplane mode on and off. As you mentioned, the issue's frequency was increasing over time, leading to more than one signal lost per day. Airplane mode solution stopped working. I have also tried to kill (and got restarted) rild, as well as radiod - with no luck. Logs (I haven't checked kmesg) revealed nothing. I'm not sure the details of your issue, but I was loosing the whole GSM/WCDMA signal, not only the Internet access. Meanwhile, the system seemd to be looking for a network, draining my battery.
I still hope that the solution was to replace my SIM card with a new one from the operator. After that, about a month ago, the issue happened only once, and airplane mode on and off solved it. It's worth to notice, that turning airplane mode on took quite long time, about 30 seconds.
I'm having GT-I8190, Omni version 4.4.4-20151108, baseband I8190XXAMG (I'm not sure if it is distributed along with the rom, or maybe resides on different partition, and is not updated with the omni rom releases).

Did you check logcat? If you didn't then logcat might show what the problem is. And your problem sounds more severe than mine. I only lose 3g but I can still call and send text messages. A problem with the simcard might be possible but it could also be a physical problem with the simcard slot though I can't say why rebooting or turning airplane mode off and back on would fix that.

I just wanted to confirm that I have similllar issue with 3g data connection. S3 mini with I8190XXAMG4 baseband. Stock ROM used for last few years (without any significant issues with 3g data connections), upgraded to latest CM11 20151017 from maclaw/novafusion. I noticed that there are some glitches with 3g data connections. Sometimes I need to tap few times before connection finally is being established. Funny thing is that I have second s3 mini with the same CM11 20151017 and all is OK.
I tried a lot of another ROMs; fifferent version of CM11, OmniROM (4.4.4 and 5.1.1), CM12.1 - problem remains - issues with 3g data connection. Is there any solution to get rid of this 3g data issue?

Yes, logcat (main, radio, events) revealed nothing but just signal drop to 0%. At that time, I didn't know about kmsg and system logcat buffer, so I haven't checked them.

Just tried this, and it helped. Usually, when something is not working, people try to turn it off and on again.
I always had rare glitches with mobile data connectivity, and turning mobile data off and on again always solved the problem. I think our problems my be hardware related. I suppose my old SIM card could have buggy software, i.e. advertising to support some newer protocol, but actually didn't. After upgrading, the phone tried to use the new advertised protocol, and got confused, or made the SIM confused.
I also know about cases, when SIM card simply died without any reason.
I used Note 2 about two years, flashed different roms and never had troubles, but then my friend used it about 3 months on 5.0.2 custom and got troubles with gsm/wcdma. My next samsung phone become our beloved i8190. Flashed it from stock to 5.0.2 CM, than 5.1.1, after month got first Cellular bugs. Tried another LP and some KK roms, my troubles with baseband became more and more frequently every day, flashed different modems, changed much settings in system.. So I was desided that it's all HW problems, and hated Samsung for such failure. But one day just tried to install Project Noble, and all this troubles gone forever. So it's just drivers, which not optimised for new Android versions. 4.1.2 mixed with old TouchWiz after fresh and clean Lollypop feels horrible, but we can do nothing with it.

But if it's hardware related, wouldn't you think that rebooting our phone or turning airplane mode on and off wouldn't fix it? And did you see in the logcat log if something happened before the signal drop? Sometimes events prior to the signal drop can also tell something about the cause.

Hardware could also have its state, which may get corrupted and reset on reboot.

Mobile Data connection not working, but there is a service and Wi-Fi

Hello,
I have quite a huge problem for me. Since yesterday I began to stumble upon problems with mobile data connection. For the first day phone restart did the job. Today in the morning it stopped working at all - no data, service or Wi-Fi. Was on the last available xiaomi.eu and thought it may be some problem with software, as the reboots helped. Did a clean flash of the same rom and nothing happened, then did a clean flash of Pixel Experience and Wi-Fi with service came back but no mobile data. Tried different APN settings, tried my fiance's SIM card nothing helped. Also - during the phone calls service randomly turns off. Could there be some soft side help? Or does it point to radio module ie. hardware?
Thanks for all the answers.

Having the same problem. Additionally, when removing the SIM card, WiFi drops out occasionally, despite me being right next to the access point. When trying to select a network manually, it sometimes says: " Couldn't find networks. Try again."
I'm on lineageos 17.1: lineage_dipper-userdebug 10 QQ3A.200805.001 be5ca755dc
And tried the V12.0.2.0 and V12.0.3.0 Chinese firmware, as well as V12.0.2.0 Global.
