Hello,

I want to share a problem that I also encountered with Powerapps in mobile version.

Every time I try to go back manually from the Barcode Scanner I get a black bar at the bottom. (Possibly a bug of the keyboard?)

Here is a video of a reddit user that shared the same problem as mine.

I'm using a Samsung SMX-110.
