[Q] Phone Freezes

Hi to everyone..well..as the title says my phone keeps freezing after seconds it boots. i was on PA v3.6 and decided to flash the newest release so i did.. after that it's been only problems. i did the wipes, but it constantly freezes.. so i decided to go back to stock and try again.. so i did with odin, but it keeps freezing even when the first settings pops out. i don't even install any apps. it just freeze, even if i reboot the phone and leave it to deep sleep i find myself with the same problem. i've been flashing custom roms since i bought the galaxy s1 and i never had any problems. i tried the dummy file thing but it keeps happening. does anybody knows how can i fix this?
Freezing is usually the memory controller working around bad memory blocks. Try reading the 'unusual freezing' thread in the general forum.

Samsung Galaxy S3 resetting

Good afternoon all,
I have recently updated my Samsung Galaxy S3 via kies to Android 4.3. I couldn't do the update over the air as it was rooted. I had to go through and root my phone again through Odin and again all that went fine.
However since doing this I have had to restore my device 2 times as it shuts down every now and then and I find I 'lose' some apps...mainly games, which I find annoying. It also wipes any saved text messages.
At first I thought it was only losing apps that I'd downloaded through other means (i.e. not Play) but it appears not. I still have the apk files stored on the phone and have tried to re-install them but I get a message of 'app not installed'
Can anyone tell me why this is the case? As I have previously said it has only been since updating to Android 4.3. Not sure if it is due to rooting my phone (i'm guessing not).
Any help will be greatly appreciated
Chris

Please use the red report button and ask a mod to move the post.
See multiple posts re OTA and root problems.
Suggest factory reset if that does not fix then flash stock 4.3 through Odin .
I know that I can't do OTA updates... My problem is that the phone will restart, without warning and when it reboots I have lost all my text messages and a few apps. Trying to reinstall the apk files gives me the error 'app not installed'
I have tried factory reset both through the recovery mode and the system settings, but nothing resolves it.
My phone is rooted and runs Android 4.3 which was updated through kies.
The apps it loses are games so that's not a major issue... It's all the text messages.
I have a very similar problem, phone always shuts down and restarts on it's own. A couple of times it has lost some apps but usually it just starts up again fine but it's very annoying. Sometimes it gets stuck in a boot loop too.
A Google search for random reboot or random shut down brings up a lot of results but no solution's, so it seems to be a common problem. It's not just the stock rom either as it still does it when rooted and running other roms.

Samsung galaxy s duos 2 rebooting

I have samsung galaxy s duos 2 gt-s7582. I rooted my phone successfully. And the phone was running good until after some 15 days, my phone rebooted automatically. It boots normally again and after some 2 minutes, the screen freezes and reboots again. I performed data wipe/reset from stock recovery but the problem is that though it shows data wipe complete, there is no data wipe at all when i restart the phone. And the phone continues in restarting continuously. Flashing stock firmware through ODIN also shows success and the phone reboots. But the old ROM is not replaced at all..Please HELP !!!

Samsung Galaxy S6 Edge Screen Freezing

I have been having big problems with my SM-G925F after rooting it. The phone randomly crashes while I am using it and then reboots, this happens about 5 times a day. I have unrooted it, tried custom roms (right now I am using XtreStoLite Deo Mod 2.4) Still it continues to do this. Sometimes before the phone freezes the sound disappears when I am listening to music, or it just crashes when switching between apps. I am new to this so all help would be really appreciated.
Do you guys have any ideas what could cause the problem? What are the possible solutions? I have already tried uninstalling unnecessary applications and booted it in safe mode. I also did a complete wipe and did a factory reset and went back to stock rom. Still no luck Thank you for helping me out!
