Hello,
recently, I have noticed an icon in the shape of a troubleshooting key appearing at the top left of the screen. I looked in the device manual (225 pages), but there is no explanation of what to do.
So far, the phone is working well.
But what actions should I take?
Thank you for your help.

Hello,
this is most likely a notification from an app you downloaded (perhaps without your explicit consent). So you need to find that app!!!

The key corresponded to an open application. It was necessary to swipe the screen from top to bottom with a finger and to make it clear. Thank you for your help.
