So I dropped my phone in water and now my fingerprint won’t work. Also every time I try to press the off and on button it screenshots. It also doesn’t let me on apps? HELP!

Your phone is water damaged. You need to back up your phone ASAP before it fails. Back up on a computer with itunes. Then you can take it to a shop to check but iphone 6 are really cheap used. You can buy another and restore your data to it.
