C1573401245902 , via OnePlus 6T , Oct 23, 2020 : Ma alert slider ain't functional from last 10 days and it is stuck on Ringing mode. Though i use d slider to put d phone onto Vibration or Silent mode but it doesn't work . I updated ma latest version to 11 as well, but no luck. Dis is pretty disappointing malfunctioning from OnePlus team. And I wonder how come the team ain't worried bout d customer issue. Inappropriate customer handling. Do v hav solution for this issue???
