Hi! I want to check if my iphone was damaged by liquids, can anyone know where are they placed? Thanks!

The most obvious one I believe is the sim tray slot. Eject your sim card and shine a light down it and see if it’s pink or not. There are usually others around the top of the phone as well. If the sim slot doesnt show water damage, that doesnt mean other indicators arent pink it just means the liquid didnt reach that spot.
