Olimpiyat Testing - Roblox Studio (gyazo.com)
As you can see in the second video, it works as intended for 2-3 seconds after you tap the screen, but after that the character starts to automatically turns. Is this normal?

A solution that I found that might fix this is going to StarterPlayer and set DevComputerCameraMovementMode to classic and DevTouchCameraMovementMode to classic
