I am trying to adjust the height of the active area of the screen as shown in image, by turning off blue areas to hide camera hole and round corners as I don't like the appearance.

The built in setting for hiding the camera only turns off the red area so the corners are still rounded.

I have tried using ADB overscan command to reduce height of the display, but this just moves the items on the screen without actually turning off those areas of the display. I want the blue areas to be completely disabled, which should be possible on OLED display.

The apps I have found all require rooted phone.

Any way to do this without root?

 

Thanks for your reply

If you know of a way to do this with root, is there any chance the permissions can be granted with ADB commands, as I know this works for some apps that require root.
