After the PUBG Mobile 4.2 update on iOS, I am facing a serious joystick and touch input issue that happens ONLY while the phone is charging.
There is NO overheating at all (I use a cooling fan and device stays cool).
This issue did not exist before the 4.2 update.
The joystick starts misbehaving (drag, delay, random movement) only during charging, and the problem immediately disappears when I unplug the charger.
I have already tested with a new cable, different chargers, and proper settings.
This clearly seems like a 4.2 iOS charging-time touch/joystick interference bug, not a hardware or user issue.
Please investigate and fix this problem in the next update.
