I had purchased a Google pixel mobile on 27/05/2017. First time when I visit to service center in the month of June at htc service center of Google in htc service center I had visited more then 3 time they had changed the mother board n battery at htc service center.
But still the mobile gets heated then I had call to Google customer care they had changed mother board again but still the issue was not solved now then I had call. I had given the mobile three time to the customer care now still there is a problem.
