My phone was in my pocket and fell in the toilet and I instantly took it out and dried it but it had a case on which I couldn't remove. I tried to turn it on and it worked but it went white for about 2 seconds and went back to normal. I had no time to fix it so I left and when I came home 7 hours later I put it in rice. So is there a chance my phone will work? And if not I should get a battery replacement right?
