I have a Asus X202E Notebook and I recently updated to Windows 8.1. Everything was normal before the process meaning, in Windows 8 there are no phantom problems whatsoever, even in the process stage/ installation page of Windows 8.1. After the installation is finished, it first led me to the start screen. It was very shaky, I can't control It I try battlin it but I can't so I used the desktop key in my keyboard to skip to the Desktop. There I saw the phantom/ghost touches. It was like a possessed mouse. Please help me. Notebook is relatively new(3 months old). I disabled the touch screen so the Notebook can work properly.
