Screen cracked then dropped in water, told its fried

@shenanigans602 depends on what you want to do with it. Do nothing and hoping for a miracle does not sound like a very productive idea. I would suggest the following.

For now stop continuing to try to charge, sync or otherwise use your phone. This potentially can make a bad situation worse.

The very first step I would take is to disassemble your phone. Use Samsung Galaxy Note9 to 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. 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. Do not use drinking water, if you need to use water, use sterile water. Also, you do not need to leave your phone to dry, Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. If you can, get it professionally (ultrasonic)cleaned 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. Keep in mind that water damage is the hardest to troubleshoot and to repair. After all that, reassemble (you will most likely need a new display assembly as well) and then re-evaluate. Hope this helps, good luck.
