[LG V30 ROMs, Kernels, Recoveries, & Other Developm] elhennig:
Hi all, since my try with Q followed by a TWRP recovery I have some strange problems with the phone:

First Signal messenger was not able to open threads and I thought this was caused by an update of the app. Then I found that all camera apps (stock LR, OpenCamera, Gcam 5 and GCam 6.1) do not run anymore, They hang when opening the app just like signal hangs when I open e message thread. I am not absolutely sure if this is related but I guess it is as all my tries to fix this were not successful:

I tried to do a factory reset and only recover user app's data with Titanium Backup --> failed

Installing the system from scratch with cleaning cache, art/dalvik and system failed, too just as using different opengapps version failed to solve the problem. At this point I ran out of ideas so I appreciate any hint from your side what else I could try. Thanks in advance!

EDIT: I just noticed that all sensors do not seem to work and logcat gives some errors regarding the sensors, too:
