Flicker Gate

I purchased surface pro 4 device soon after it first came to market. I highly anticipated this device because I have a physical disability, and writing on paper for me is quite problematic, so the digital pen support and windows 10 support were ideal in my case for make notes during lectures. About one year ago I occasionally started noticing stone flickering issues, especially when pro 4 got a little hot. I thought that the problem is probably temporary and will be soon resolved by ms. However, the problem still exists, and worse, the screen flickers even when idle now. I am highly disappointed with my (quite expensive) purchase, and I am now in a problematic situation when I need a performance device for studies, but cannot afford purchasing another computer. If only I knew that things will turn that way when I purchased that thing…
