Hello, My iPhone 6 Plus has water damage to a certain extend, and the screen comes on fine but is not responsive. The battery port works perfectly fine. How much would this be to fix?

Hi Donny Banks, kindly do bring the device in for a free diagnostic service. With water damage it's always best to bring it in as soon as possible to see if water got into the internals and to effectively clean it. Thanks.

They give free estimates, I'd take it in. Their prices are reasonable, I had a smashed screen on a brand new tablet they had it fixed the next day for $80 total.
