Any of you guys have had dead pixel issues with the quest 2, switched mine on today and after a while I noticed like a cluster of three or so green off centre right side on left lens, really annoying. The one year warranty is due to run out on 28 of this month, though I do have an extended warranty.
I took it back to a well known high st store who eventually exchanged it for me for a new headset, I got a refund on the extended warranty, their way of doing things, and had to buy a new after care warranty, a £10 extra as price had gone up, but at least the whole guarantee starts afresh.
I do sit by window at times and the bright sun does affect the controllers, but I am careful not to let sunlight directly into lens of quest, I take it there is no way sunlight can affect the front of the quest, causing dead pixels etc.
