Exact same occurrence after my wife dropped the phone on a beach in Mexico. I bagged in rice and then no more response. I bagged the phone in ISOPROPYL RUBBING ALCOHOL 91% for 12 hours to clean up the salt and bagged it in rice again for 48 hours. It now turns on, turns off, I was able to charge it, I was able to connect to wifi (I know this because I have my photos auto save on google photos and I noticed on my computer that all the photos from the day the phone fell in the ocean are now online. I was also able to take pictures, video, use the flash. Here's the punchline. The screen does not work. As far as I can tell the only thing not working is the screen. At this point I'm going to try to replace that.
