Hi..........the touch screen on my xperia play seems to have stopped working ??? any ideas, the only button that works is the app that takes me to all the other apps its on the bottom row in the middle

Restart the phone.

With this type of problem I would always advise running an update, even if restarting helped this time as there may be another problem.
