I dropped my 4-month old Galaxy S5 into the pool and retrieved it right away, wiping all the water off immediately. The phone works fine, but when I lock it, it would unlock right after! So every time I press the lock button, the screen would turn black, but then would just end up opening again to the lock screen. No matter how many times I do this, it doesn't lock. I've also restarted my phones a couple of times, and nothing has changed. Currently, my phone is sitting in rice in case there is any water left on the phone. How do I fix this bug? Please help!
