My iPhone fall in water I pick it up due to it water resistance , I charge it and it work perfect but later in the day I notice water trace on it screen .. So I dry it and still use it and charge suddenly it just off and on… But now it didnt show the apple logo again all screen white but it shows charge indicator when low.. I check the water damaged indicator but it still water that mean it don’t suffer from water damage …please what can I do to it should I try to dry it again or change it screen…
Take it to a reputable phone repair shop for liquid damage evaluation, it’s the best chance of getting a liquid damaged phone working. From those symptoms liquid has gone inside the phone.
