prad1382 , via OnePlus 7 Pro , Jun 12, 2021 : Got Oneplus 8T couple of weeks ago and he'll lot of issues. Have sent it back for replacement, not sure how much time that would take. But have a made a mistake by buying Oneplus phone. I can see almost all of its models are having lot of issues after update to Android 11. I have been using Oneplus for many years but this is the worst phase and not much is being done to correct it. Should I have invested in some other brand???
