Hi. I have a Samsung Galaxy S3 Mini. Today I dropped it in water. It wasn't really that deep so the phone wasn't in water all the way. I picked it up right away and looked if something happened and it seemed like it was working. But now, I was about to charge it but I realized that I can't. The phone doesn't charge. I tried different charger and everything but still nothing. I guess it's because water got in the USB port. I haven't any other option but to send it to repair because I flashed custom roms so guarantee or the original service wouldn't do it. I'm wondering what is to be done, if I can do it myself, and if I can't, how much will it cost? Thanks.
