some place on screen no touch response etc
2) and same problem I am facing when I put my phone on flat surface
I thing Sony must resolve this issue as soon as possible
Take your Xperia SP to a Sony repair center
Enable Glove Mode and restart your phone. This has worked for me so hopeful this will work for you as well. Otherwise the only option left is to take it to repair centre. I donot know if even they have any solution.
