iPhone 6S screen burn in/shadowing after water damage

[MKB_UHD]

iPhone 6s was splashed by water. I didn't notice that untill I plugged it in and it didn't charge. I turned it off, opened it up and let it dry for 24 hours. I didn't notice any traces of water inside the phone.
After the 24 hours , the phone was charging with no problems and everything seemed fine. But then I noticed that any static screen if left for 3-5 seconds it will appear as a burn-in in the lock screen (or any solid color screen) for few seconds.
It looks exactly like what OLED screen shows when they burn in, except in my case it
appears so fast (3-5 seconds of static image) and disappear as fast.
I tried Google but I couldn't find one thread similar to my problem.

Thank you

There is nothing you can do, there is damage to the logic board, which is shorting out your phone. Even if it continues to work ‘normally’ for a period of time, it will just intermittently fail at random times until it completely powers off.

Thanks for replying. But there was hardly some water in the lightning port and when when I opened the phone I didn't find any water or even moisture.

I feel that the image retention means that it's a screen problem. Or maybe something with the cables.

The problem is very characteristic (image retention that come and goes fast) but I couldn't find any source with similar description on the internet.

Rest assured, water did indeed get into your phone. Just because you can't see it doesn't mean it's not there. It tends to seep into the the bottom side of the logic board, beneath the shields. Water damaged phones tend to develop latent issues but sometimes they do recover fully without further intervention. However, because you have screen issues, it's clear there is water related damage somewhere.

It could just be water inside the layers of the screen assembly or it could be related to the LCD driver circuit, which is near the screen connectors, underneath he CPU shield. If you want to diagnose this further, then try a replacement screen to see if that clears up the issue. If it doesn't, then you should have your phone looked at by a shop that does micro-soldering repairs.

Replacing the screen did clear up the issue. Thank you very much.
