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?
