[Q] Xperia P - random scrolling, opening of apps etc
I have a problem with my Xperia P. Sometimes, it randomly starts to do things when the phone is unlocked, even if I am not touching the screen. It seems to register a touch, when there actually isn't any. Because of this, it randomly starts opening apps, scrolling and sometimes even moving widgets (it somehow registers a long touch followed by random scrolling).
I figured it was some sort of software error, so I used the PC companion program to repair my phone (wiping all settings but not the SD card) and for good measure, I reset the phone from the Android menu, also wiping the SD card. Then I reinstalled my apps etc and everything seemed fine, but after about two days the problem was back.
Is this a software bug that more people have, or is it a hardware defect? Also, I read using a third party charge could cause this. I use the official Sony charger of my old Ray, but it is rated to have the same voltage and less mAh, so that can't be it, right?
