Anyone has any update if oneplus is oow and if they are offering exchange coupons on oow phones same like in-warranty phones?
do newer models still have this issue?

From what I've seen, this seems to be an issue most common with phones released from 2020 to mid 2021 (OnePlus 8T, Realme X7 pro, redmi note 10 series etc)
