I have a Samsung Galaxy Note 8 running Oreo 8.0 and have started to notice an odd issue when playing games.
Whenever I'm in a shooter game like PUBG Mobile, Bullet Force, Critical Ops etc. I encounter choppy touch input when trying to aim by swiping my finger around the screen; I would drag my finger and get no response for a split second then a 'jump' to where my finger is. Also, this seems to be more of an issue in the top half of the screen than the bottom depending on how I rotate the phone in landscape mode.
I tried reflashing the stock Oreo firmware with Odin and factory reset the device twice, all to no avail.
What else can I try to fix the problem or at least identify whether it is a hardware or software problem?
Thanks in advance.
