I like keeping my phone on Adaptive Display most of the time but prefer to watch videos in the Amoled Photo screen mode. Does anyone know if an app like tasker will allow you to set up a rule so that when you open a video app like MX Player, the phone will automatically switch to Amoled Photo mode, then when you exit out, it will revert back to Adaptive Display? If so, can you show me how? I don't mind paying for the app but I'd like to know if its possible before I do. Any help would be much appreciated. Thanks.
