Iphone 7 short circuit?

So yesterday i dropped my phone in a puddle. I turned it off for about 2 hours then powered it back on. Later that night it cut off and keeps going through this phase of the apple logo appearing then shutting back off. I have restored this phone twice. It is still doing it. Help please! Should i just suck it up and file an insurance claim? I have asurion through sprint.

How much will my iPhone repair cost?

I have an iPhone X and the screen needs replacing but everywhere I have asked has recommended I take it to the Apple shop for repair. I've booked in for repair but some places say it'll cost £280 for repair whereas on the website it says with Apple care it's £25. I'm unsure to how much it'll cost as they're very drastic differences. As to whether I have Apple care, when entering the serial number it says:
'Your product is covered for eligible hardware repairs and service under Apple's Limited Warranty.
Estimated Expiration Date: 20 November 2018'
Could anyone tell m how much it will cost?

Why Are Pictures On My iPhone X Unediting Themselves?

So for a couple of months now, the photos on my X have been randomly unediting. I'm not doing this myself. My portrait pictures are reverting to normal pictures, my cropped pictures are being un cropped, any way I edit my photos, they are being changed back to the original. There's no way this is a storage issue because more than half of my storage is unused. Is this happening to anyone else? I know it's a first world problem, but please help!
