Sorry but no - if by underwater you mean diving, and not putting your hand 0.5m underwater or similar depth snorkeling. Gopro has tiny sensor and crappy lens and it shows, even if you set the bar of quality as low as phone screen-only. You can end up with reasonably nice pictures from time to time, I've ended up with dozens from all activities I've mentioned (and that's using gopro hero 2 with custom housing in the past, now newer variants), but you will lose many more moments due to rather poor device performance.
