Hi jhnkrls0901,
Good day.
Is your firmware currently on the latest WW-14.0400.1903.065?
(settings> system> about phone > software information> build number)
If yes. Could you please kindly tell me below information?
(1.) Does any specific app cause this problem to occur? Please show me the game app name and version.
(2.) Could you tell me in which scenario do you play the game? (e.g. dark environment)
(3.) Could you show me a short video about your operation? ( including close the auto brightness)
Please upload the video to a cloud and paste us your share link.
Thank you.
