I got a One Plus 3T. It's a brand new phone. But suddenly when I tried to record a video it showed that "There was an error recording the video". And in the gallery I couldn't play the video it said "Couldn't play the video". After that I checked every app that has the camera and it didn't record videos. Sometimes the normal picture taking was working. And sometimes it won't even take a picture. At that time all my notification sound stops too. After I rebooted the phone it started to work fine. But after a couple of hours the problem starts again. I did a factory reset and cleared cache. But the problem still exists. Please help. I would really appreciate that.
