Hey all, I posted something similar back in May. 

Has anybody else had a screen issue with the Sony Xperia 10 plus?

When using my mobile, sometimes the screen becomes unresponsive for a few minutes, the only way I can get it back working is to use the side button to turn the screen off and back on. 

Other times it will suddenly just start jumping, the screen seems to have a mind of its own, buttons will be pressed and the screen will swipe etc. Again the only way to stop it is to turn the screen off. 

Has anybody got any idea how to fix this before im forced to purchase a new phone?

Many thanks
