Keyboard letters and numbers: k, i, m, unlock screen 9.

Hello everyone!

So I made the mistake of thinking my iPhone 11 Pro would be resistant to sea water. I was in the ocean in Hawaii and I wanted to snap a few photos. At one point my phone did become submerged, but not for very long. Maybe a couple of seconds. I have dropped it in non salt water before, fully submerged, but didn’t have issues after.

After the salt water incident, my phone seemed to be working except for a few keys. When typing, I couldn’t use certain letters in the bottom right if my screen. For example, I would press on k, and would have zero response. I also notice my phone would become slower when using multiple applications.

I am thinking I may have to replace the whole screen. Has anyone came across a similar issue? If so how did you go about repairs?

Thanks for the help!

@ray914b you know appear to have a water damaged device. You should treat it that way.

The very first step I would take is to disassemble your phone. Use these guides iPhone 11 Pro Repair to help you disassemble your phone. Take a careful and close look at all components and connectors. Truly assess the damage. Look for major corrosion, evaluate the pins in the connectors etc,. Take a look at all connectors as well as cable ends. You will have to remove all the EMI shields. If you do not remove the shields, you are not cleaning the board. Once you got the gross contamination cleaned, use 90%+ isopropyl alcohol and clean your parts some more. For a proper cleaning, use this guide. It was written for an Apple iPhone 3G but it is still pertinent to your phone as well. I can not stress the importance of a good cleaning enough, so do it over and over while replacing the alcohol after each cleaning. Do not use compressed air for the cleaning since that can drive liquid as well as corrosion particles into areas that will cause trouble later on. If you need to use water to clean the gross contamination, do not use drinking water, use sterile water. Also, you do not need to leave it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. It would of course be best to get it professionally cleaned in an ultrasonic cleaner, but this should at least get you in the vicinity. Do not forget to replace the battery. This is a must and not an option. It will fail if you do not take care of it now. After that, reassemble your phone and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Yes it is possible that you will need to replace the display assembly to get your keyboard working again but it is also possible that this is due to failed components/corroded connectors etc. Keep in mind that water damage is the hardest to troubleshoot and to repair.
