If you disable auto-rotate (i.e., force portrait mode), a notification icon shows up. It looks like the vibrate notification, except without the vibration lines. Inside Settings -> Display -> System icons, I can disable other notification icons like the battery, battery %, wifi, etc., but not this one.
Is there any other way to disable this notification, or even other ones not present in System icons?
I'm on Android 7.0, Sony Xperia X Compact.
