Let's see. You knew you could not afford another phone. Yet, you wanted to test it by going swimming?
I don't know about the alcohol, but maybe the phone will come around once it's fully dry.
But regardless, I hope you learned your lesson here. Although these phones and some cases are supposed to be resistant, that doesn't mean we should be taking our phones in showers or going swimming with them around here. Every phone is not built the same, or how it should be, and someone's phone eventually was going to fail.
