[Oppo Find 7 and 7a] griMa010100:
Hi guys,

My OPPO find 7a is doing very weird things. I am trying to describe what is does, because I lack a proper expression.

I do a fresh install of a custom Rom (I used LineageOS and Omni) with or without open_gapps and SuperSu after around 10 minutes telephone starts to open and close apps in a very rapid fashion. It really renders the phone unusable.

I suspected whole problem comes from LVM. Thats why I am here.

I used mount command before and after "weird behaviour":

ad before: I think this is the correct way. It is mounted to 9016-4EF8.

ad after: Something forced to unmount 9016-4EF8.

I am a very interested to solve this problem, but I admit I am a bit lost here. My best guess it is has something to do with permission etc.

I'd be very happy someone could guide me in the right direction.
