What do I do? Do I get it replaced? And If I do how much will it cost?

First off you need to clean the phone completely . The blurriness is likely moisture between the lens and the lens cover on the case. But the phone itself need to be cleaned or it will corrode and die This guide will help with the teardown https://www.youtube.com/watch?v=2wliGGHr…. Clean every connection with a soft toothbrush. As well clean the logic board; use a 99% isopropyl alcohol for all cleaning. Now is the time to start drying out the phone. Set the screen in a desiccant or silica gel leave it in for several days moving it from time to time to get the max effect from the desiccant. Use a blow dryer on a low heat setting to dry the rest of the phone. Only use a hair dryer once you have cleaned the phone completely with the alcohol. Do not attempt to dry the phone if it’s still wet with water with the blow dryer as this only spreads the water. Replace the battery with a new one considers the old ones done. Clean your camera lens and the lens cover on the case .Clean again with isopropyl alcohol let dry and when you think everything is clean and dry reassemble the phone (make sure to clean the contacts on the screen after removing from the desiccant). Once you’ve reassembled the phone it’s time to power it on. Hold your breath and hope for the best
