Since the update ,my Sony X1 randomly kicks me back to home page from gaming apps and also the game play is severely hampered down to less tha a frame per sec. It's not my WiFi connection or the games, so must be my system, please help
I had problems like you caused by the SD card which made the system unstable.
Take out SD (if you have one inserted) and see how it goes.
In my case a brand new SD resolved the issues.
