Xperia L touch screen problem

[Bhoopendra]

My Xperia L was working just fine. I updated the android to the latest 4.1.2 build number 15.0.A.2.17 a few days after which i started experiencing this problem,

 When i put the phone for charging the touch screen doesn't work properly. If i press alpabet A it just clicks many words all by itself.. Moreover i cannot unlock the pattern lock unless i remove from the charging. My phone does not recognize the touches when it is charging.. I did a facrory reset and the problem started again, I did a software reinstall using pc companion and the problem started again after 5days!! Please help me!

Is it a bug?

is anyone facing a similar problem?

This may be your chargers problem. Try 1. charging from PC via USB and 2. Charging from any other Wall Charger of Xperia phones( if not available try with other android phones charger). This problem should not occur.

Hello, my Xperia L does this too

If issue happens only when phone is on charging try another power supply or connect phone to a computer with USB cable
