I noticed that multitouch does not work properly in some games. The display reacts weird in landscape mode when you place both thumbs on the screen and move them at the same time. This is especially evident in apps/games where you have to look and move at the same time (for example Dead Trigger or WoT Blitz). I did a factory reset but the issue is still present. I did not have an issue like this on my previous phone Xperia L1. Could this be a software or hardware problem?
I tested the touchscreen with Sony's own support app which comes preinstalled on the phone. According to the test everything is fine. The touchscreen works without any issues in most apps and games which I have installed. In the game WoT Blitz, the touchscreen acts a bit weird, when you move one thumb to look around while you use the other thumb to move around your vehicle. It is not a big issue because most apps/games seem to work. For example on Pubg Mobile I don't have any touchscreen issues. I find it odd that this particular game WoT Blitz seems to have problems with the touchscreen.
