Well, android is now better after a lot of big version updates,it works well in many ways,it could even change my system resolution in settings,and the resolution can be changed in a game called PUBG mobile that its 720 turns to 1080p,if you use super high quality.
But it is not the point that changing the resolution,it is about bug.when you click the resolution,it shows a white line means the resolution you can choose,but not in fact.
