I recently noticed my Galaxy Note 9 shows like a rectangle clearer in the middle of the screen when the brightness is slow. Could this be a configuration, a default behavior or actually an phisical issue? Thanks
I just noticed the same as you have pictured here on my note 9. Strange if my screen has deep black background it isn't there but with regular use on any given app it's visible. Had phone for few years now. Bummer there's no fix. Definitely not burn in.
