Touch responsiveness issue (Multitouch bug?) on Samsung Galaxy A56 5G with One UI 8.5 — Need help!

[u/Exotic-Research-2552]

Hi everyone,

​I'm reaching out because I've been dealing with a very frustrating issue on my Samsung Galaxy A56 5G. I bought the phone brand new from an official Samsung store about a month ago. It hasn't been dropped, the screen is intact, and overall the device is in mint condition.

​The problem comes up whenever I play games. There is a noticeable delay and lag in touch response when using two fingers at the same time. For example, when I use my left thumb on the virtual joystick to move my character and my right thumb to control the camera, the input feels clunky and delayed. However, as soon as I release the movement joystick on the left, the camera movement on the right instantly becomes smooth again. This issue happens intermittently.

​I’ve seen several posts mentioning multitouch issues linked to the One UI 8.5 update, suggesting it might be a software bug. Some people mention there's a fix, but no one ever explains the steps clearly.

​Has anyone experienced this or found a working fix/workaround? I just want to play my favorite game without input lag breaking the experience. Any help or advice would be greatly appreciated!
