[Q] Strange behaviour after long time up and running
I have some issues with my phone behaving strangely and forgetting settings after long power-up times without reboot.
I am on rooted Adam kernel 1.6 knox-free with stock 4.2.2 rom XXUDMH5. I only flashed Adam kernel because whatever i tried, I lost Wifi with stock kernel after I tried CF-Auto-Root (got no clue why, but I am not the only one). Phone normally works quite fine, and after greenifying some apps and disabling some bloatware I normally get battery times of four days+ with moderate use (I am not a power-phoner).
However, after some days of power-on time, the phone starts behaving strangely. I got issues with screen auto brightness not working (screen staying on lowest brightness level all the time), touch screen not reacting properly, apps not starting etc. Two times the phone got hot while charging, apparently something running on heavy duty, with the result that after hours of charging battery power increased only little, if at all. Normally those issues went away after re-booting the phone.
Today, after charging over night, I found the phone with screen on, and looking into power history I found that it had been on for six hours. Apart from the hardware damage this might bring (screen burn-in), the other issue is that after the re-boot, I lost almost all settings. I had to enter passwords again for Samsung account etc., and I had to re-configure everything from keyboard settings, vibration feedback, screen turn-off delay, and remote access features.
When I tried to login to Tomtom live services, I had to enter the password again, too, and then the app told me that my account was already associated with another phone (which it was not, of course). Fortunatelly it allowed me to transfer to my "new" phone.
My questions are: Are those settings (screen turn-off delay, keyboard, remote access etc.) kernel or rom related? Does anybody know where those are stored (some xml file perhaps)? Can I make a backup (I have titanium backup) and restore only those settings if need be?
Many thanks in advance!
