My phone was submerged into the water when I was washing my hands, the phone didn’t die and I thought that was fine, I was testing it’s camera and speaker to see if it was fine, they were. And then suddenly the phone’s screen had that purple filter on about 80% of the screen the apps and background is still visible. My phone is a Samsung A21s it’s now in the uncooked rice for about 6 hours now. Will this do the trick? If not, what are the things I can do? I’m only a student and short on money so I don’t have anything to get the screen replaced
Hi, It seems as though the display has been damaged by the water (hopefully that’s all) and it may need to be replaced. The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone’s operating design and could damage the components. The corrosion starts immediately and is ongoing until it is completely cleaned away. Rice does not fix the problems caused by corrosion Rice is for dinner, not repair First do not try to charge or to turn on your phone and then remove the battery as soon as possible from the phone to minimize any further damage. Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use “rubbing alcohol” as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board. Remove the shields that may be covering some components as the water may have got in under there. The ends of any flex cables and their connectors need to be cleaned as well Hopefully after you have done all this the phone might possibly work correctly again. Here is a link to a teardown video for the phone which may help. If cleaning the phone with IPA doesn’t completely fix the problem then initially as a DIY repair all you can do is to replace the display assembly and see if that is all that is wrong with it. Replacement assemblies (supplier example only to show cost) are available online. Just search for Samsung A21s LCD display replacement to find suppliers that suit you best. If this process seems too daunting, take your phone to a reputable, professional phone repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
take it out of the rice now! rice can get into nooks and crannies in the phone and cause more problems. if u havent already pull the battery. water + electricity = corrosion and blown components. if you can leave the phone by a heating duct and let it air out for a day or 2. the screen being purple might mean that its already got some irreversible damage. but you wont know for sure until you open it. if youre capable of atleast opening the phone that would help in drying it out fast and you can take some rubbing alcohol and clean it out a bit as well. ive heard that you can use desiccant to dry it out instead of rice. but im not sure about that one.
