I have had this problem since I got this phone 2-3 weeks ago. It really only happens when I am playing games and never when in an app. The issue is that the phone has difficulty operating on more than one finger on the screen at a time causing the camera on Cod Mobile or Roblox to jitter making it almost impossible to play in any way other than one finger at a time putting me at an unfair disadvantage that shouldn't really be there to begin with. 

I would love any help concerning this problem. Thank you in advance.
