[A_P1]

Hi,
I have problem wit black square that appears in middle of my app screen between forward and stop button, see the photo.
It's not part of design and it appears when I lunch my app.
The phone is Samsung A52.
Can someone tell me what is going on?

Do you have a notifier together with a timer?

[A_P1]

Yes
Notifier to keep screen on

Well that is your black rectangle then.

Use a different method to keep your screen on. There is such a block in Taifun's Tools Extension, or you can create a 1x1 pixel video player that loops a small video.

Or change notifer background color to transparent.

Yes, that was it
Thanks
