Water Damage - No Wifi. Does Replacing Wifi Antenna Work?

It was raining outside one day. I ran into the house but dropped my phone outside the door. The next morning I opened the door and saw my iPhone soaked in water. I dried it with a hair dryer. It turned on. Everything's okay except it always shows no wifi and the lock button doesn't work. I'm wondering if replacing the wifi antenna will fix the problem?

Answer this question I have this problem too

Is this a good question?

I wouldn't go that far and would say thet the logicboard is toast.

since you didn't wrote anything about opening and cleaning the iPhone - the problem could come from shorted parts inside the phone.

the only useful way to handle somethig like that is cleaning the logic board.

get some isopropyl alcohol (>90%) or some electronics cleaner and a soft paintbrush. also get some tools to open the phone properly.

use the logic board guide to open the phone, the needed tools are listed in the guide.

chek the logicboard and all connectors for fluid residue - clean them with the alcohol/paintbrush

let it dry (don't use the hair dryer!!)

after you're done, reassemble it and try it again

It happened a few months ago.. I opened it before and cleaned everything with a Q-tip. Wondering if it's still useful to clean it with alcohol again?

Is it possible that only part of the logicboard is toasted? Only the wifi and lock button don't work.

it's always good to do that after a fluid damage - and since the damage was in that area - i would not hesitate - both parts are in the same area - so i would concentrate my "search & clean job" on that area
