If you feel the ambient light sensor is malfunctioning, go to a service centre. Samsung has done an amazing job with auto brightness on S8, and I doubt they would mess it up in N8
Thanks for being with Samsung and sharing your concern. We would like to inform you that please follow the steps below to make settings correct :- • Brightness: Adjust the brightness of the display. • Auto brightness: Set the device to keep track of your brightness adjustments and apply them automatically in similar lighting conditions.
