Hi Mohd Faizal,
Malaysian user here in Sabah, my unit (warranty expired) is replaced with refurbished unit (Free of Charge) under Advanced Exchange Program by Microsoft Surface Team back in end of June 2017. Lucky me.
Screen flickering is not happen yet until now (touch wood) as my usage of this machine is at least 8 hours per day, everyday.
However, I just using it for YouTube, Netflix, browsing and Microsoft Office, and I dare not to install heavy software to stress it after i got this refurbished unit.
Pity me but I do change my mind now, I shall install PhotoShop and AutoCad in near future for learning purpose. In case of the screen flickering coming back, what I was thinking now is, to standby an external monitor with the mini-display adapter (not surface
one because lost confidence and not wanting to support Microsoft hardware anymore)
Think this is the only cheapest way I can do with this premium and failed product from Microsoft, because hardly sell my unit in my small town here, and also not afford to get another laptop/tablet as well.
I suggest you to get the refurbished unit since the current unit of yours is not use-able when flickering happens and it is Free of Charge, better than doing nothing. As I am prepared if my current unit screen issue come back again for the worst case scenario
like I said above.
