Hi, I know it's an old post but I just got the same trouble since 1 week :
- freeze in about 2sec to 1 min maxi
- click power ==> the screen shut down
- click power ==> the screen come back in lock mode
- try to unlock ==> and it freeze while showing the home screen ... or when i'm lucky I can use it 1 or 2 min
It was hard to change any setting on the phone ... 1h to enable debugging :-(
But the good thing is that I think I've found a solution :
For information, I've got a LG G2 D802, 32go
HW version : Rev 1.0
Android version : 5.0.2
Kernel : 3.4.0
software version : V30d-EUR-XX
The configuration working for me is with this changes :
- enable "developer options" (see instruction on internet)
- in "developper options" check the 3 options :
--- Usb debbuging
--- Force GPU rendering
--- Disable HW overlays
To explain how I found the "solution" :
After having tried a factory reset without a real success.
With USB Debugging i've succeed to have less lag when the phone was plug to my computer... but still it was still freezing some times and all the time, when i unplug it, it freezed again.
I've try reboot factory reset, reboot from adb and other thing without success.
I then try "Disable HW overlays" as it was always freezing when the screen refresh. And with this option the freezes stop happenning. But I had some lines on the screen at each application switch. So I also try "Force GPU rendering" and with it, the switch is ok (without flash lines during the switch).
I think that only "Force GPU rendering" and "Disable HW overlays" should work ... and maybe only "Force GPU rendering" ... but as i need my phone I wont give a try now ... maybe in the next months.
My phone is now working for 1h without a freeze !!!! Youpi !
