My phone was submerged into the water when I was washing my hands, the phone didn’t die and I thought that was fine, I was testing it’s camera and speaker to see if it was fine, they were. And then suddenly the phone’s screen had that purple filter on about 80% of the screen. My phone is a Samsung A21s it’s now in the uncooked rice for about 6 hours now. Will this do the trick? If not, how much would a repair cost?
