Full screen mode: Android square button overlaps edit mode button

[joabach]

Dear all!

Since when Qfield uses the full screen mode, I cannot edit datasets any more, because the edit button (low right) is under the square button of Android.

How can this be resolved?
Is there an option to avoid the full screen mode?

Hardware: Shiftphone 5me
OS: ShiftOS-L 2.1 (Android 8.1)

Thanks
Joachim
