Noise in videos iPhone 6s Plus
Today I noticed the noise in the video (from the iP6s Plus). I shot videos through Instagram, Snapchat, Facebook, and there's still noise there. The dictaphone is fine, it does not bother in recorded sounds. I turned on the YT video (https://goo.gl/uyjG8P) which is no sound, I put the volume on the max, and the noise was heard when attached to my ear. Video noise is even when I record from the selfie camera. I uploaded a video (w/microphone from headphone) and the noise there is also heard.
