Like everyone else here, worst experiance with a camera ever. Hero 8 black lost connection with app whilst updating firmware. Now wont turn on. Rang customer service and told it was the fault of the SD card I was using. Rubbish! App is useless, experiance over last two years as follows camera works when it feels like, touchscreen is hit and miss, very slow to upload when it worked and now apparently unfixable. Better off using a smartphone than this piece of junk. Shame as on the rare occasion it worked the picture quality was good. However if relying on it for those once in a life time moments forget it. Could go on about poor battery life and other stuff but no point. Camera bad,customer service bad. Avoid like the plague and spend your money elsewhere!
