How to remove rounded black corners which appeared after system upgrade?
Found this on reddit (thanks to &quot;jyapayne&quot;):
adb shell settings put secure sysui_rounded_size 1
adb shell settings put secure sysui_rounded_content_padding 5

First line is the corner &quot;roundness&quot; and second line ist the padding of the status-bar elements to the edge.
