Abhi Dahiya , via OnePlus 7 , Oct 21, 2019 : I recently ordered OnePlus 7, 8+256 variant from Amazon India. I was upgrading from OP3T. Upon receiving it, i found it okay. And then after 1 day of usage and setting up, i discovered it to have uniformity issue. On Dark Grey backgrounds (in apps), top half and bottom half part of display would have different hue. Top would display light grey and bottom dark Grey. Being very particular about displays, i ordered a replacement from Amazon. But even the replacement unit had the same uniformity issue, just that it was now from left half of screen to right half. After this i decided to visit OnePlus service centre. I showed them the problem, and despite having received a replacement already from Amazon, they out of courtesy provided another replacement unit. And guess what! To my surprise even the 3rd unit has the same uniformity issue. And it's even worse. I am not even sure what to do anymore. My 3T had a great screen. No such issues. I don't think it even matters to have another replacement whatsoever. It might end up anywhere! And if i go for a refund, who to ask about it? Started at Amazon and now have a OnePlus Store unit. And not just OnePlus 7, even 7T owners are complaining about reddish/greenish tints on their device and it's even worse. What has happened to OnePlus QC? Are they letting literally any kind of display pass through their manufacturing? No checks and balances at all?
