Xperia M2 dual touchscreen not responding when kept on flat surface

[Jun_Xperia]

Touch Screen not responding when phone is on flat surface, heard about Xperia SP had the issue and it was setting issues in glove mode, but M2 dual not have any glove mode and still its having similar problem. Please advice solution for this problem. Is it Sofware , hardware or anyother setting issue?

I have the same problem. Tried Pcc repair section but gives me error can't repair. Update from device says software is uptodate. Update from PC gives error. What should I do? Please help. This drives me crazy.
