So I'm curious if anyone knows what is going on. Whenever I record a video using the default camera app, any 3rd party camera app, or Instagram, it sounds like there is a bunch of static and ruffling when I play the video back. But when I use snapchat or Facebook to record a video, the sound is crystal clear. Also calls are clear on both ends and voice recording apps come out clear. I have cleared cache/data, started my phone in safe mode, and finally factory reset my phone to no avail.
