This has been a recent problem with my phone, I never had any issues with it when I first got it. Basically, when I record a video the sound is extremely muffled when I play it back. I just recorded a video of my record player with the volume turned up very high, and upon playback it's barely audible. I transferred the video to my laptop, and on my laptop's speakers there's no sound but some ambient hiss. I know it's not my phone's speakers because I can play music through them and they sound fine. It's just an issue with videos. The voice memo recorder is fine, as well. Any ideas what it could be?
