Sometimes when typing I can't use the back/home keys and the screen becomes unresponsive for a few seconds then will work OK for a while then do the same again.

Do you have facebook messenger? Can you check if the same occurs in safe mode?

Hi Plumber44,

Welcome to the community,

Adding to the questions above, are you able to advise if this happens when using any specific app, or is it random?
