All is in the title: I want to always show the status bar, even in fullscreen mode (basically, I want a deactivation of the fullscreen mode). Ideally, I would like to display it in portrait mode when I am holding my phone in landscape mode.
The reason is because I have a notch and I do not like it visually, so I would like to use it as a permanent status bar.
I searched on the Internet, in the play store, but I found nothing so far.
For information, I am using the oneplus 6 with android 9.
I read this question: Always Show Navigation Bar Nougat / Disable Immersive Mode but it is about an older version of android.
EDIT: the latest Android version (10) made it worse. Now this isn't even possible to keep the bar black.
