I have just migrated from oneplus, unlocked and restored my user apps. However, after using for few hours, I noticed my phones hangs and freezes and it can only be functioning after a hard reset. I have tried factory reset but the problem is still there. I have only rooted with Magisk, none other modifications. Any advice experts?

I have read around regarding this problem without luck, and hope that someone can advise if I have missed anything.
I used to use this phone and as I liked to tweak it was running a custom rom (think it was Wanams). Anyway I got an upgrade ages ago, and my wife carried on using the phone for a while. As she just needs a standard rom I recently decided to factory reset and use Odin to flash the newest stock rom (N7100XXUFNE1 - UK). This is when the problems started. Initially the Wifi wouldn't come on, but after factory resetting and using the Samsung Updater in Kies I finally managed to get Wifi back. Then, while setting it up and installing apps from the Play store it started freezing and had to be rebooted every 5 or 10 mins. Finally after doing this a couple of times, all the apps were installed and after leaving it to "settle" it seemed to be better. Now however, 2 or 3 times a day, when playing games or using other apps, it will just reboot.
What I have tried is:
* I have tried clearing cache through the stock recovery
* Tried a number of Factory Resets
* After reading about the SDS problem I have tried running the "dummy file generator" to fill the internal memory and this completes ok. I guess this means that although I have memory that is/was susceptible I applied the original SDS fix early enough with the custom rom that all the memory is still ok?
As I have the newest bootloader I can't downgrade that, but as I don't care about triggering Knox I was thinking of rooting and installing a custom rom to see if any of the other Kernels help?
Has anyone got any idea's what could be causing this and what I can do to fix it?
Thanks.
Hello,
It seems that my G925T has some problems with soft reboots. I don't know exactly what the problem might be, maybe you can help me troubleshot.
So I have followed up all the things a normal user might do like:
soft reset, hard reset, odin stock rom flashing, smart switch disaster recovery, disabling certain apps, going to safe mode, cleaning cache, resetting cache and dalvik, but nothing. Flashing a different custom rom, custom kernel but still problem remains.
Even after following up with all these steps, my phone still reboots unexpectedly while I use it and even i don't use it. An average is that my phone gets these unexpected reboots like everyday. Maybe 3 time a day, or maybe next day. It seems like soft reboot.
For an some addition information my phone is IMEI repair, but everything is fine, i can get updates as i am currently on the official stock ROM.
Currently I am on latest update DOJC.
What do you think it might be the problem ?
Has soft reboots to do with IMEI repair ?
Is there anyway i can troubleshot this ?
So I have a T-Mobile LG G4 that like every other G4 had the bootloop problem when I got it. I sent it to LG and they promptly fixed the issue. My current issue has nothing to do with the bootloop I believe.
Because the G4 wasn't getting the Android N update fast enough and also because I wanted to play around with Android's full potential, I decided to root the phone a little over two weeks ago. The process worked and I decided to install a custom ROM. That also worked. I have installed four or five custom ROMs built on Android 7.1 without issue, or at least without any major issue.
However last night I decided to flash Genysis ROM on Android 6.0 because I wanted to play with Xposed. I made a full Nandroid backup of the CRdroid ROM it had been running and then wiped and flashed it using TWRP. When I installed the ROM it didn't work for whatever reason, freezing up and frequently becoming unresponsive. Over about 30 minutes I managed to enable USB debugging and reboot it to recovery (why I didn't shut factory wipe it from bios I'm not sure).
Now any ROM I try to install doesn't boot up. It never gets past the OS loading screen with the ROM logo. On 6.0 ROMs it says it has optimized the apps but gets stuck on starting them. The Nandroid backup I made does the same thing, even ones I made early that day and one from several days ago.
The backups had that one app installed that shows the logcat while booting up and while I'm no expert it seems to get a loop loading the audio drivers. I don't know if that's the cause or if it's just coincidental, as I've never heard of audio drivers preventing a boot, albeit my experience is with Windows PCs.
If it would help I can attempt to take a picture of the screen while stuck, although the text moves very fast. I can access the TWRP recovery just fine but don't know how to/if you can dump logs.
Any help would be much appreciated! I can attempt to supply an information that may be needed as well.

why not start from 0 and flash latest KDZ with LGUP.
https://forum.xda-developers.com/tmobile-g4/development/h811-kdz-file-t3607807
For sure I'll try that. I'll let you know if it works, thanks!
Follow up- I eventually found the free time to work on this and flashing the kdz worked! I actually had to use LG Bridge as LGUP only found my device as unknown.
Thanks for the help! Back to flashing ROMs for me.
I had the latest 6.0.1 samsung rom (CPK2) which was giving me problems with freezing. So I am trying to upgrade to an 7.x.x rom, either RR, AIPC, or Lineage. But none of these roms allow the T800 boot to get beyond the initial splash logo screen. I am using latest TWRP, 3.1.1 to wipe and install rom. I am not getting any install errors. Boot loader is confirmed as CPK2.
FYI, I am able to get back to the samsung rom by reflashing it with Odin.
Update 1: In the final attempt of upgrading I installed the official 6.0.1 fw which boots fine unlike the aforementioned alternatives (very strange). However, lock ups and now screen blanking more frequent. This time wiped everything including storage. It looks more like a hardware issue but I wonder if this could be malware even after wiping everything. I will have to take this in for repair but have little hope of solving this problem.

My wife has the US Cellular 10.5 variant (T807R4). It was freezing so frequently it had become almost unusable for anything but watching videos. Rooting and disabling most of the Samsung apps did not fix the problem. I wiped the system with TWRP only to discover that none of the custom ROMs would work on this model. I downloaded and flashed the stock Samsung MM firmware (and it sat on the opening splash screen for at least 15 minutes before it finally booted up) and for the hour I used it after setting it up, I had no problems. I had previously cleared the cache with Titanium Backup and that also seemed to be a temporary fix. My conclusion is that something is happening when the cache fills up that causes the freezes but I'll need more data to say that for sure.
Just an update: I was going to have the hardware looked at so I wiped everything including the storage. But when I took it to the shop and was asked to demonstrate the freezing the tablet wouldn't. So I took it back and it was running OK until a couple weeks later when the same problems reared there heads.
Somehow I managed to get a 7.1.2 installed and the T800 is running great...so far. I'll post back if the freezing starts again.

Please explain the steps to install 7.1.2 (and which ROM you used) and update on the freezing issue. Most of the freezing issues I have read about seem to be on LTE variants (SM-T807x) so I was about to buy a wifi only (T800) tablet, thinking that would be a solution to the problem. If that's not the case, then I shouldn't waste my money.
The instructions for installing a non-stock ROM are on the dev's host page in Tab s forums. I first tried Resurrection Remix and now am on LineageOS. It was only after I wiped the internal storage area that I was able to get past the 7.x.x boot screens.
I found the stock rom 6.0.1 freezing issue persistent. I believe the problems started for me with XAR H4 and really picked up with K2 (roms supplied by sammobile). The tablet would frequently just freeze while working in an app: the screen and hardware buttons would not respond at all. Never had that problem with Android 5. The only thing I was able to do to unfreeze it was to reboot into download mode then restart the OS from there. I sometimes found that if I left it frozen overnight it would unfreeze itself by morning.
Hi there,
Yesterday I rooted my oneplus 5T and installed TWRP 3.2.1 & masgisk. Then, I´ve installed Pixel experience AOSP which seemed like fairly stable from the description. Everything went fine, the OS started I started configuring it then after setting the password I got the OS having always the setting app to crash. So, I thought well, I can just go to recovery and try once again factory reset. Otherwise, I can mount the recovery and install another ROM. I went to recovery and to my surprise it was asking for a password and mine didn´t work. I tried the factory reset and still the encryption stayed. I found that this version has a decryption problem and all my files were encrypted and not accessible, that was fine, since I had everything backed up. So, I have installed the new version of TWRP which seems to fix this issue after loosing all encrypted file. I have formated the data, system, dalvic and cache and installed once again pixel exerience but the OS keeps on bootloop. Have anybody seen something like this? How should I fix it? My best guess was to reinstall stock OS via adb, but in the past I've rooted a couple of devices and I've never seen something like this.
Thanks in advance
