I entered in the pool with the watch knowing its waterproof but I stayed a bit longer with it after about 50 the screen went black, I quickly put it in a bag of rice and after pressing some butons it vibrates for 1 sec. And after some time of pressing it stars to vibrates for much long, now it vibrates continuously without stop, sometimes the screen reopens and shows just "Garmin" on it. . . Is there I can solve it ?
