920FD on latest OXX2COH2 mobile data comes on while on WIFI - Galaxy S6 Q&A, Help & Troubleshooting

I just updated my dual sim S6 to the latest firmware. Now the issue is, that while on wifi, the mobile data comes on and goes of every few seconds periodically. I see this as the icon comes and goes.
Tried reflashing the phone several times, this happens even after factory reset with stock only apps installed.
The problem is, that the battery seems to drain much faster because of this.
Anyone with a similar experience?

AOKP JB 4.1.2 Mobile data dropping and not reconnecting

I’m currently using AOKP Jellybean 4.1.2, the supposedly stable, reliable milestone version found here: http://forum.xda-developers.com/showthread.php?t=1804223
I'll try to be as thorough as possible in hopes that someone will respond and know what to do. I apologize in advance for being long-winded.
I didn’t have any issues last night when I first flashed the rom. I was able to watch youtube videos using the mobile data. I was also able to turn on wifi to sync some files from my dropbox to my phone, and then turn off the wifi with no issues. However, today after connecting to a wifi network to download a few things and browse the web, I disconnected from the wireless network and the mobile data curiously did not start up again. I DO have cellular service (3-4 bars), and I can make phone calls and check my voicemail by pressing and holding 1 on the keypad, but my mobile data doesn’t work. I looked around for some solutions, and I've since restarted my device several times, tried toggling airplane mode on and off, and did several combinations of reboots with airplane on/off and no dice.
Everytime I use the toggle in the notificaton bar area to turn off wifi, my internet connection goes with it. It says “no internet connection” in the notification background at the bottom of the screen. Once I turn wifi on, I get my internet back and it says “at&t” at the bottom, but I don’t actually get mobile data because apps like “At&t Visual Voicemail” which require mobile data to function don’t work.
I tried flashing the 1.85 radio to see if it would connect to mobile data, and same issue persisted after reboot and dalvik/cache clean. After that failed, I flashed the 2.20 radio + RIL zip files seperately (which is what I understand came with the rom), and still no dice.
For reference, my HTC One X was rooted with 1.73 firmware (I never tried to update it until last night). I did the CID spoof method to unlock my bootloader, and installed the newest version of TWRP on it. I flashed the rom and the gapps package. I used TiBu to restore program settings and a handful of my out of market apps, and the rest of my purchased apps downloaded automatically from the market after connecting with my google account. I had literally just finished reinstalling the last of my apps today via wifi when this issue started to happen.
I'd really prefer a practical method of getting this fixed that doesn't involve starting over with a fresh rom install. Reflashing at this point would be something of a nuisance since I don’t have much free time to begin with. And hey, it took a long time to load up all of my apps just right
However, if there is no other fix that anyone is aware of, I guess I could reflash or in the worst case try a different rom. It’s a shame because the rom otherwise is really smooth and runs great on the phone, in addition to not using a whole lot of resources and having a decent battery life.
Thanks in advance for any suggestions and solutions.
Here is an image of my battery drain screen showing what my mobile data is supposedly doing despite not being able to get a true data connection. Even with my wifi off, there is supposedly medium mobile signal.
And attached is another image of what happens when I turn my wifi off. I pulled the notification pane down and you can see that it says "no internet connection" at the bottom. Also, you can't really see it in that cap, but the mobile data bars behind the notification area are colored white, and there isn't any "H+", "4G", or "LTE" notifiers visible.
Edit: Attached a third image showing the "white" signal bars (i.e. no data connection). Yes, my mobile data is turned on, and I'm obviously not in airplane mode.
I figured it out eventually for anyone interested... Apparently the APN were not set. They existed on the APN list but were not visible due to a glitch in the ROM I guess. I had to add a custom APN and then the other ones suddenly appeared.
Thanks anyway.

Nexus 5 Wifi Issue

So I've had my Nexus 5 for roughly around a month and I hadn't experienced any issues others have had with wifi not connecting until now. My N5 will show im connected to my home wifi with full bars, but going into quick settings shows it to be orange. Suggesting there's no data transfer, I cannot use any internet based apps with wifi. I've tried some suggestions, switching my router off then on, rebooting the phone, turning some settings off in the advanced panel in wifi settings. All have failed.
I was just wondering if anyone else has this problem and if anyone has a fix to it.

There was a thread around here somewhere that suggested turning off your mobile data helped fix this problem, I think it was in the N5 General forums.....here it is:
http://forum.xda-developers.com/showthread.php?t=2550690
Don't know if it'll help or not, just saw your thread and had just looked at the other one, figured I'd toss it out there.
Thanks for the reply, just tried that solution but still no luck.
I have a similar problem except that there are phases of wifi not working.
Sometimes I would have around 20-30 seconds of WiFi not working and there would be no data transfer.
Speeds are still fast when it is working however.
I played a little with only using mobile data and no wifi, and everything worked. (Small sample size however).
Seems like this is a WiFi only issue.
So somehow overnight the wifi has managed to fix itself, will report back if the problem returns.
The issue with the wifi returned unfortunately.

Don't know if you've tried this but change your WiFi frequency band in advanced setting to either "5 GHz only" or "2.4 GHz only," whatever your router uses. Might be worth a try.
Thanks for the help, but I've tried changing some settings in advanced wifi settings but it hasn't worked. Even what you recommended I've tried that before and it didn't work.
wifi issue
Also I have the same issue - Im connected to router by wi-fi, home and work and time by time (5x a day) wifi stops working. Wifi is enabled in settings, but there is no connection. Restart the cellphone helps, but after that, maybe an hour, it appears again.
Issue was in 4.4 and still appers in 4.4.1.
Yet did not found how to solve it.
I have the same issue on my gnex running shiny 4.4, but I also had the same issue on 4.3. Tried the wifi options, nothing worked. Unfortunately, no solution for this device that has to last one more week. The double swipe down and tapping wifi gets the connection back, but it is only a work around.
The N5 connects seamlessly to my home and work wifi. A few days ago, I flashed the hammerhead factory image, TWRP and the 4.4.1 update.

Hey,
I have the same problem with 4.4.2.(factory rom, no root or not unlocked). Sometimes the wifi not works and get orange. I must put airplane mode to fix it. Its annoying.
But as well happens to me:
When I go out from office or home (where I have wifi connections saved in phone) the phone automatically switch to data plan from carrier. But when I come back the phone stays with data and there is not automatic switch to wifi. Sometimes it help to put wifi off or always airplane mode on/off for a while.
I do not know if it is normal behave of android but I would like have automatic switch to wifi.
I tried to change wifi details (changing bands, etc.) but not helped.
Please help. Thank you.
Is custom ROM or kernel will fix it??
For some unknown reason, as soon as I updated my router's firmware, the problem disappeared.
Updated Android 6.0 solved the issue

So I had the unfortunate experience of having my wifi go down while on vacation and for 3 weeks I spent a good chunk of time wiping and reinstalling multiple versions from Cyanogen, Paranoid android and 4.4 - 5.1 to no avail. I just did another factory wipe today and installed the new Android 6.0
The Finger Pointing Game is OVER
Read through 30+ pages of other android users with similar experience and some people send their units back to LG and some even managed getting a new handset. There was never any hardware issues with my unit I just couldn't turn on the WiFi but after the install WiFi works? Guess next time you push a software update to our Phones CHECK YOUR SH*T google and Maybe DON'T Take 3 months to FIX your F*CK Up.
I have a similar issue. Since Lollipop my phone almost never automatically connects to my WiFi anymore. What's wrong?

Having lots of issues with cell connectivity

So recently I've been having a lot of issues with my cell reception. Randomly during the day I would completely lose my reception. However the icon in the status bar will show I got a full connection. Mobile data works. But I will be unable to receive / make calls or text messages. A reboot will fix this. I've had this issue ever since an ota update from sultanrom. I've since tried flashing the stock ROM back but it happens on there as well. I'm currently on the latest sultan mm version. But this used to happen on his lollipop version as well It mostly seems to happen when charging my phone. I've tried different firmwares and modems but the issue is still there. This is a big problem because I've gone for 10+ hours several times without any cell reception thinking all was fine because the status bar shows a full connection. Has anyone else had this issue? I really need to get this sorted as it makes my phone unable to do the most basic things a phone should be doing.

modem_err - signal loss - random-reboot - high battery drain

Hi,
my phone lately shows an high battery drain, random reboots and signal losses.
Aside from supersu and adaway everything is stock. last-kmsg shows "modem_err"
A few days ago I updated my phone from MMB29V to MOB30H, right after this I went on holiday. (left country)
While being there everything worked fine.
But right after I comeback home the phone started to act strange (see title).
Anyone an idea what could cause the behaviour?
Maybe the update? And I didn't noticed it in holiday because of my disabled data connection?
I tried:
a full wipe, reflash of stock image
flash of old radio
looked out for wake locks (there are non)
using phone without apps (only stock)
Might flashing old bootloader/kernel help?
Maybe interesting:
My provider (Klarmobil (T-Mobile DE third-party)) tends to switch my network mode between 3G and HSPA,
from what I heard and see this depends on my data usage. (HSPA while surfing, 3G while idling). I have the "feeling"
it disconnects when it tries to switch.
Thanks for your help!
Edit:
Added another set of logfiles, showing a "signal-loss", it got so far to ask for my pin again.
Sadly errors still keep happening. I tried the march build and also a custom kernel, no change :crying:

Contant modem restarts on mobile data

Hi,
Since the latest update my OP7Pro has issues with mobile data. I use 2 SIMs, first one is "nju mobile" (offshoot of Orange), the other is T-Mobile. When I set data to use nju, it restarts the modem every few minutes - I can tell because "SIM Tools" app disappears and reappears every time it happens. Now I'm forced to use data on T-Mobile, but I think this also restarts modem, it's just less noticable because there are no "SIM tools" for it.
I also noticed that the phone never enters deep sleep now (as indicated by AccuBattery). It's not rooted, running stock OxygenOS.
Seems to me like a modem driver issue, but no idea how to approach that. I'm not keen on reinstalling everything, setting up everything again will take me 2-3 days that I can't spare if I'm not certain of success.
