1.) SOUND QUALITY - The sound quality from the camera itself is not very good BUT when you watch videos through a phone or other device the sound quality is excellent. for some time. Fixing this is easy as all you have to do is remove the SD card and hold down the power button until the camera turns off. Once the camera is unfrozen, you can reinsert the SD card into the camera. Overall this is a great camera and while the audio and video quality may seem sub-par, both are excellent when viewed on a phone or other device. The E-commerce Hero7 comes with a protective case, charging cable, camera, two stickers and a screw to fix the camera to the bracket.
