This might be a bug because I noticed once I plug the charger in my Z2 and try to start an app (say Clash of Clans) a white screen just slides through and nothing happens. I just press the multi tasking button to force-close it. Also tried to force stop the app before relaunching it, same problem. Tried to restart the phone via the power button, however it takes longer time than normal before it boots up again, like 3 to 5 minutes. What could be the cause of this issue?
