This happens quite a bit on my phone and other Android device I have. What happens is and it doesn't matter wether it's You Tube Gmail or any other app I get this message saying for example You Tube (or what ever) isn't responding you have then 3 options 1. Wait. 2. Report it. 3 Close it. What is causing these messages to appear from time to time on both devices and what to do to fix the problem this will happen on either 4G or WiFi? Any one else had these messages appear from time to time? TIA
