Dropped phone in water, works fine but battery makes sizzle noise
I accidentally dropped my phone in water (toilet), immediately took it out, washed/rinsed it quickly, and took out the battery and SIM card and dried it. After a while, I tried the phone, and everything works fine except the SIM card being undetected and a constant sizzling sound whenever the battery is in. I tried putting in another battery to see if the battery was the problem, but the sizzling sound was still there. I don't think there is any liquid corrosion damage, as the phone was in contact with water for less than around 30 seconds and the back inside of the phone was barely wet, but I think there might be something wrong with the place where the battery connects in the phone (the four yellow pointed things). For now im going to let it dry and try the battery again. What should I do?
