So I recently upgraded to a Note 4. I've always used auto brightness, and of course enabled it right away. Since then I've been noticing that the brightness reverts to 50% (turning auto off in the process) a few minutes after auto is enabled. This is infuriating. I am perfectly capable of disabling auto and setting the brightness myself, but I would prefer to refrain from that until it's the only option. I figure it's a software thing. Does anybody have any insight?? Any suggestions would be much appreciated!
