[Q] Odd problem.... lose service after hitting power button/screen off

Hello all,
I've been searching for 3 days now and cannot find a solution to this problem. Normally I try to avoid starting a thread since there is usually one on the internet somewhere already, but this has me stumped.
I have a SGH-I337M on Bell, was running SlimKat 4.4.4 with no problems, and wanted to upgrade to LP. I first tried installing the CM12 optimized build, but it would never get past the boot screen. Then I tried GPE 5.0.2, and it looked beautiful and ran smoothly, but it would not automatically connect to Bell's network. If I went into the mobile networks menu and waited for it to scan, and then selected Bell, it would connect, but a few minutes later it would disconnect again. WiFi worked fine. Needless to say, having no constant service was unacceptable. After that I tried installing SlimLP (wiping cache, system, etc in between all installs) and had the same service disconnection problem.
Then I tried:
-flashing modems
-flashing back to stock from SAMmobile and reinstalling (where a similar problem persisted)
-starting from fresh to GPE, then starting from fresh to SlimLP
-reflashing GPE with all 3 kernel choices, cutting out as many installation options as I could
-trying different combinations of preferred wireless mode, APN, etc
Nothing works. I am back on SlimLP and I have got it to the point where the Bell service will work as long as the screen is on, but when I hit the power button and/or the screen goes off, the network disconnects again. If WiFi is NOT on, when I hit the power button and unlock the lock screen, it will automatically connect to Bell again, but this does not happen if WiFi is on.
Any ideas here..? I've read countless threads and nothing seems to work. Any help would be much appreciated as this is driving me crazy!!

The issue has been resolved! Apparently I was too impatient and was not using the proper modem
But I can't find a way to delete this thread. Damn I must be getting old

[Q] Nexus 4 - Wi-Fi Problem on 5.1.1 ROM

Hey guys,
Yesterday I've flashed the Euphoria ROM (5.1.1 version) and I've noticed an unusual problem.
My Wi-Fi turns off itself when I turn off the display (after 2-3mins).
When I press the lock button to wake up my phone, after 1 second the Wi-Fi turns on automaticaly, but in the meantime (when it is off) I don't receive notification.
I've tried to: flash the updated radio modem and bootloader, flash the Google stock ROM (always 5.1.1 and I had the same problem), flash the Google stock ROM (this time the 5.0 version, and the problem was disappeared).
How can I fix this problem?
Thanks to those who will help me

Any idea?

Go to WiFi advanced settings and check the policy about keep WiFi while locked.

Click to expand...

That option is already set to "Always"...

It was a router problem...
Solved now.

[Q] I9505 Lollipop - no internet - tons of "stopped" errors - Recovery: No Command!

[Q] I9505 Lollipop - no internet - tons of "stopped" errors - Recovery: No Command!
Hello again! After my wifi problem on Kitkat which was solved by reflashing several times (as suggested by a forum user ) I tried flashing to lollipop (5.0.1) which worked out perfectly, no problem this time. I flashed lollipop and rooted on friday and during the whole weekend everything worked perfectly. The phone was fast and smooth, no lags and no errors.
Today I woke up and as soon as I tried to use the phone I got tons of "unfortunately stopped" error messages. Things that give the error: Youtube, gmail, google,play store,bluetooth,samsung account, and a long etc. the camera does not work either and I can't connect to internet using WIFI nor mobile data.
As soon as I dissable mobile data and WIFI the errors go away, and everything seems ok. but of course without camera nor internet which makes my phone useless. (can only receive phone calls, which I tested)
EDIT: Seems like I found another Symptom/Error: I can't see the files in my Sd card nor the internal storage since I'm on a "fresh" factory reset System I only have access to the built in "My FIles" app and it shows "No files" on the internal storage, and does not even show the external sd card. I tried using an OTG cable (Which worked fine before all this happened) and it recognizes there is a usb drive connected but "My Files" shows the same: "No Files" even though the usb stick works fine and has several files.
Searched the forum but could not find this particular problem where all the errors come from turning on any kind of internet access (which does not work anyway, since besides the errors I can't connect to internet neither on wifi nor using mobile data)
I tried Factory Reset twice and as soon as it starts reinstalling the "system" I start getting those same tons of errors and If I try using my wifi password to connect to internet it can't go past the samsung account or google account step, it stays there giving errors on a loop. So I try setting up the wifi "Later" and it's able to complete the factory reset, but without fixing anything. No camera, no wifi, no mobile data, as as soon as I try to connect to the internet I start getting all those error and almost any imaginable app (of the freshly factory reseted S4)
I think I'll try reflashing it as soon as I get home from work, but would it help???
Any ideas?? has someone else had this problem before?
If reflshing does not work could I try downgrading to kitkat?
Did my phone died this time for ever???

Data connection stalls after some time

Hello everybody,
In Fall 2015 iI decided to root my Note 4 too. I have tested several different ROMs until now but one problem always remained. After some time of normal usage my phone somehow stalls the data connection. The signal indicator hat an exclamation mark next to it and nothing else helps than rebooting the phone.
Does anyone know a solution to this problem? This is what I tried so far:
I'm currently running on Ressurrection Remix v5.6.7-20150409 on a SM-910F.
-Different ROMs
-Updated Modem & Bootloader
-checked APN settings
-go to flight mode and back
-open the cover and move the sim card a little bit
Nothing of the above helped in any way. The data connection is just gone and will only work again after a restart of the phone.
Thank you for you help.
best regards,
ex069

no one?

I need help please!

Wifi not turning on (i9505 - Stock rom)

Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.

No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?

My wifi is not being enabled with this rom. Does anyone know how to solve?
