i bought my xperia sp a week ago.from the next day onwards i have started to face touch which sometimes is not recognized by my phone.i updated to the latest firmware but the problem still remains and it is even more during charging.all i have to do it is to enable and disable glove mode to bring it back to normal functioning.please help is there any solution to it or is it a hardware problem?
First,you are in the wrong section.Secondly,I have to tell you that the touch problem is a very common issue for the SP,I have read a lot about it.The touchscreen does not work when the phone is laid on a flat surface,but when in hand it is ok.I recommend taking the phone to a sony repair center.
Moved. 
but the touch problem even occurs while in hand.is it some hardware problem then?
If software repair/update did not resolve the issue, most likely it is a hardware issue.
Contact your local Service Centre to have your phone checked.
