Multi touchscreen bugs

ZF Model: ZB602KL
Firmware/APP Version: PKQ1.WW_Phone-16.2017.1910.059-20190920
Frequency of Occurrence: Often
Rooted: No
APP Name: Life after

It seems so confusing everytime I played Life After, the touchscreen seems doing as its own will..
E.g: when I tried to run, then suddenly it opens my bag or inventory though i didn touch the bag icon.
