Touch does not respond properly

[Mechosive]

Dear sir,

The touch in my sony xperia j does not respond properly and seems to lag a lot.Random windows open automatically.

Even though i have updated it, the problem still persists.

Please resolve the issues as soon as possible.

We are looking forward to you.

I suggest that you try to run a software reinstall using SUS.

If the problem still remains you should contact your local support team, to have the phone examined and fixed at an repair center.
