I have successfully gotten Screen Mirroring to work with the Raspberry Pi 4 B + 7" Touch Screen with my Samsung Galaxy Note 8 running Android 9. Using this screen, I can navigate the phone, but there are some issues.
First Issue
The area where I touch on the RPi Touch Screen is off by several pixels in the Y-axis (vertical) when in Horizontal mode. In Vertical mode, the X-axis (horizontal) touch is off by a significant margin. I also noticed that this offset is changed depending on where I touch the screen, whether its at the top of the screen (it's off by about 20 pixels) or at the bottom of the screen (it's much closer to my actual touch).
Is there a way to offset the touch input from the screen running the RPi to the phone? I don't see any options to offset where I touched.
Second Issue
There is no way to return back to the OAP home screen without physically unplugging my phone. Can a button be added to the top or bottom of the screen? There is unused screen space that looks like it should have had a button to go back or quit.
Thanks.
