How to fix my iPhone 12 Pro Max touchscreen not working after water damage?
Partially dead screen, iPhone 12 Pro Max. I dropped it into water briefly. Touchscreen.only works in some areas now.

There is no way to fix a water damaged iPhone. Water damage is irreversible. Schedule an appointment at your Apple Store Genius Bar, where you'll be offered the opportunity to purchase an Out of Warranty replacement phone (for about 60% of the cost of the phone when it was new) or buy a new iPhone (honestly the better solution). Apple won't attempt to repair a water damaged phone at all.
