MY cup of water leaked while my phone was on the same table, and now my phone keeps leaking water! It's an Incipio case with a gap at the near bottom. (Not a feather case)
iPhone 6s, iOS 9.3.2, Incipio case
Sorry, but you should switch off the phone as soon as possible and put it into a bag of rice for a couple of days. Or visit an Apple Store or Apple Authorized Service Provider and see if they can save at least some data. In most of the cases, water damage will cause your device to fail sooner or later.
Are you saying you can't get the case off? If so, try a bit harder. It's keeping the water in contact with the phone.
Water leaked into my case and I can't get it off!
