Hi @rismose ,

Sorry to disappoint you but mobile phones do not have separate video cards.

The graphics handling is done by the CPU.

Since it appears that the phone has gotten wet, was it properly and thoroughly cleaned?

By that I mean was it stripped down and the shields that cover the ICs removed so that any water and corrosion that may be under them has also been removed?

Water and electronics and electricity don't mix well and problems can occur if it hasn't been totally cleaned as the corrosion is ongoing.

If you want to save the phone open it up and thoroughly clean it as described before or contact a reputable, professional mobile phone repair service experienced in liquid damage repair and ask for a quote.

It may be that the phone has to be placed in an ultra-sonic bath to ensure that it is totally free of any corrosion.

My only advice after this is never trust that an electronic device is totally waterproof.

The waterproofing integrity may have been compromised at some stage due to handling etc without you knowing. A slight dent or crack in the case that has gone unnoticed may be enough to allow the water in .

Here’s a link to the ifixit [[Topic:Huawei P20 Pro]] guides which may be of some help
