Many modern smartphones are designed with a hole in the screen, to place a camera or other things there. This can be beneficial when the operating-system is designed to only use that space for status-symbols and other information that does fit there, so that apps can have more screen-space, but apparently, recent operating-systems (including /e/OS/) also extend apps into that area.
For example: when viewing sufficiently tall/wide images or using the zoom-function in the pre-installed gallery-app, there will be a hole in the image, effectively changing the image while looking at it, and one cannot even zoom out to work around that defect. Additionally, the corners of such images can be invisible, due to rounded corners of a screen; which is acceptable when using the zoom-function, but not at the preset/minimum size.
While that is arguably a defect in the gallery-app (and other apps), that should be corrected there, it would be useful to have a setting that reserves the area, where the screen has a cutout, for status-symbols (the entire width or height, whichever is shorter); or if that is too complicated to implement, perhaps an option to only use a part of the screen (basically, adding empty borders).
An example for when a smartphone, with rounded corners and a cutout for a camera, is in horizontal orientation:
(o| )
The area between ( and ) represents the entire smartphone, o represents a cutout for a camera, the space between ( and | is the area that should not be available for apps when the suggested option is on.
