Ubaid142 , via OnePlus 7 , Aug 8, 2020 : Hi Everyone, I recently had an issue with the alert slider in my device. I usually don't play around with the slider and my phone will always be in the ring mode. Few days back I casually checked the slider and it did not respond at all. I tried different methods but none helped. It works in one situation only which is that I need to keep the slider in the vibrate mode then restart the phone, then the phone will be in vibrate mode. If I need the ring mode, I have to move the slider down to ring mode restart the phone then the ring mode will work. Can anyone please help me with this.
