Microsoft knew about the screen flickering issue on Pro 4 and arranged to extend the warranty to 3 years. Unfortunately, my Surface Pro 4 is just past the 3 years. I feel that since my Surface was registered when I bought it that Microsoft should have notified me that my Surface was in the batch of known hardware defects. Had I known about this issue, I would have taken care of this issue immediately. Instead, I was left to discover this on my own over time.
My surface Pro 4 really works well for me. Just the screen flickering problem stop me from continue my works.
Microsoft should take up the responsibility to inform all the registered users since Microsoft knew that this is a major problem to their users.
Hope Microsoft will take action.
