How can update my c4 in 6 version

[gunaji]

i am also facing same touch pad problem with my xperia c4 dual.

i had done repaire using pc companion but problem solved by this is just for small time again same problem start.

i had update mobile 5 to 6 times using pc companion but the problem is still remain. touchscreen goes wild when touch.

Even sony service centre not helping in this issue. I dont expect such service from SONY . very disappionted with sony service. please check your update on pc companion and c4 dual model and rectify problem. This issue is damaging your image in mobile market from very long time.

if such things continuos i will suggest that dont buy such product from sony.

 please look into matter and let me know.

regards

gunaji
