Got my GoPro Hero 4 wet in the pool. I walked in the pool with the waterproof case but it had the opening in the back since I got the digital touch screen added on. Off ourse this was the last day of my honeymoon and I forgot I didn't have the full waterproof case on!! Anyway it was submerged for seconds but clearly soaked. I tried turning it on right away by mistake saw the red ligh heard the beep then it went completely dead. I went right to the Internet for answers. I didn't have rice so I took the battery, digital screen and memory card out right away. I put tissue all around the GoPro and stuffed tissues inside the battery slot. Then I put the GoPro and the digital screen separately wrapped inside a ziplock and placed them in the sun/heat for hours.. Nothing worked then when i I got home 2 days later i put everything in rice and a sealed tubber ware. I tested the GoPro every other day to see if anything improved but no life... Then a over a week later I plugged in the GoPro for a test and the red charjng light came on!!! It charged but still would not turn on.. Finally another week later I check the GoPro after a charge and it turned completely on even the display screen worked without any issues!!!!!!!! So the moral here don't give up!!! It took over 2 weeks for mine to completely get back to life but it happened and I couldn't be happier!!! Saved myself from spending the money over again and I am happy I was patient!!!!!
