data connection is maybe the problem
i have these freezes too since i updated to 4.1.2.
but in my case it's only when i have mobile data connection or w-lan connection turned on. If i turn off any data connection, it works the whole day without freezing!
It's for two weeks now and today i decided to install CyanogenMod 10.1 to try if this solves my problem.
I'm about to synchronisize my apps (does it automatically when entering google account and choosing "restoren from my account") and the first freeze occured (W-Lan on). But this time the light of the touch keys is full functional. When i touch the screen, the background light of the touch keys turns on. But power button, volume up/down and the touchscreen are frozen.
What I've done:
- rooted and installed CWM
- Cleared Dalvik cache
- wiped all other cache partition and stuff
- installed CyanogenMod 10.1 nightly build 20130208
- factory reset and so on like described in the manuals for installing CFs
Original data of my phone before installing CyanogenMod:
So it is a bit confusing that this only happens with data connection turned on.
I've also read some threads with analytics of the update code and the SD fix so i am well informed now and think it's because of the eMMC bug where it tries to repair the corrupted sectors and freezes while doing this (cause after ~20 minutes everything is fine like nothing happened).
Has anyone an idea or a solution now besides sending it to the local dealer and change it for warranty reasons?
