Ravipaladiya3421 , via OnePlus 5T , Aug 5, 2020 : When i call through phone application and record the same call via inbuilt call recording, the recording of the call is distorted and in slow motion. I thought it might be because i was talking through my bullet wireless z but, same problem even in speaker mode and handset mode. I then tried third party appilication but there the same issue as well. I think there is a bug. Now i have switched back to the android 9 , and there is no such issue. And there was one more issue. In android 10, the camera app was not able to switch from 4:3 and full screen to 1:1 frame. Even in protrait mode. Please check. I will be updating back if the problem is solved. I have seen so many complaints on community app, but i think oneplus now means new customers and does not think about old customers. Very much disappointed.
