Touchscreen becomes wierd using two fingers, either it recognize as one point when two fingers are not that close or it can't track both fingers well. This could be shown easily when turning on the pointer location.
And I found this problem the moment I switched from Xperia Z to Z3+. This issue may not affect daily use but will ruin gaming experience like DJMAX TECHNIKA.
Hope this could be solved with other problems in the next patch 😆
