Xiaomi 15T Pro Overheats and Lags While Playing Call of Duty Mobile

I have been experiencing severe overheating and related lag issues while playing Call of Duty Mobile on my Xiaomi 15T Pro for approximately six months. The problem has become much more frequent over the past month and has completely ruined my gaming experience.

As the device heats up during gameplay, an app called Joyose starts running, causing severe lag in both the game and other applications. The problem does not go away even when I use a cooling fan. When Joyose starts running, I exit the game and close the app. After launching the game again, the issue seems to improve temporarily, but after a few minutes, Joyose starts running again and the same lagging and freezing problems return.

In Call of Duty Mobile, I give basic directional commands such as right, left, and forward, but the device does not register them correctly. It behaves as if the screen were wet, making random movements and triggering actions I did not intend to perform. When I reported the issue to the seller, I was only told that it might be related to game optimization, but no concrete steps were taken to resolve the problem.

I believe that the excessive overheating I experience while gaming, Joyose repeatedly activating on its own and causing severe lag, and the touchscreen detection problems may be related to a software issue. I request that the device be thoroughly investigated and that the problem be resolved through a software update or that a permanent solution be provided.
