I got mine replaced earlier this year and the new one is working fine so far, and has been posting in this thread before. As this seems to be escalating to #flickergate I just wanted to share my story, because it's strange to see that hat people here had
to pay for their replacement and that there doesn't seem to be any clear policy regarding support for this issue.
Mine was a month or so Out of Warranty, but I had the flicker issue before mine went out of warranty waiting for a software fix. I'm in a country with no official Service Centre or Microsoft supplier (Malta). After finally getting in touch with the UK branch
of the support, they were aware of the issue and offered me an Out of Warranty replacement.
I got mailed UPS tracking receipt to print and put on the package. UPS picked up the faulty device at my doorstep, and I got a new one delivered to my door a few days later. I didn't pay a single cent for my replacement, except for the cardboard box to send
it off in.
I was amazed and really happy with the support and the speed of the change, and this is what I would expect everyone with the same issue would get.
Maybe I just got lucky or something? Who knows? But If everyone with the same issue got the same kind of service I got, I doubt this would be much of an issue, and people would be praising Microsoft for awesome support instead.
I hope Microsoft take notice and you would get your devices fixed or replaced, with the same kind of speed and service that I got.
