SudipBasuRay , via OnePlus 7T , Apr 17, 2021 : They really messed up with the new android os 11 update. got the update today . below are the things are facing issue . 1) screen refresh rate 90hz is feeling pathetic. 2)messed up wrap charging. now taking too long to get full charged. 3)hotspot getting disconnected after a certain time. previously was updated my phone through oxygen updater. today got the hotpatch . but its look like they are now focusing more about 9 series. will wait for the next update if the issue will fixed then its okay . if not they i will exchange this phone and buy samsung next . they are really very good in terms of monthly update. i know some moderator will close this thread soon. cheers to them also.
