How to resize active screen area / change height of screen?

[Daniel Warren]

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?

I can't imagine you can do this without root: it's changing the way the display system works, so if Samsung haven't provided the option you'll surely need to be able to grant something system privileges in order to make that change, and that's what root does.

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.
