I have a Samsung A20 that got water damage and now it just gets stuck on the Samsung logo when tried on and when I put it on charge it shows the not charging logo. Is the motherboard broken? or can I still get fixed??
John Uitzinger you have not told us what you did about the water damage. So this answer is assuming you have not done anything. Yes, if you have put it in Rice it is the same as not doing anything. You do want to stop turning it on, trying to sync or trying to charge it. that can make a bad situation worse. The very first step I would take is to disassemble your Samsung A20. Use something like this video to help you 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. If you do not remove the shields, you are not cleaning the board. 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 it to dry for a day. Isopropyl alcohol in the higher concentration will evaporate quickly and dissipate the water. The importance here is the cleaning. It would of course be best to get it professionally cleaned with an ultrasonic cleaner. 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. After that, reassemble your A20 and re-evaluate. For as long as you have not cleaned your board and replaced the battery, everything is just a guess. Keep in mind that water damage is the hardest to troubleshoot and to repair. It does not matter if is was exposed for 2 seconds or 2 hours, what matters is where the water (particulates) did the damage. If you see something odd or find something that does not look right, you can always post pictures with your question for further help. Adding images to an existing question
