Just over a week ago my phone developed an issue with the middle of the screen and it doesn't respond very well to touch. So buttons on a keyboard or trying to move or touch icons in that area. It sound similar to https://talk.sonymobile.com/t5/Xperia-M4-Aqua/Touch-screen-middle/m-p/1121942#M6826 I have tried in safe mode (http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008) and it is still the same. I have run tests (https://www.ifixit.com/Guide/Sony+Xperia+Phone+-+Service+-+Test+Menu/24223) using touch screen and you can see the issue quite clearly. Any advice or is the phone screen dead? Thanks.
