My samsung galaxy 531h touch is not working and it has a little water inside of it
Water and electronics and electricity are not a good mix.
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 start immediately and is ongoing until it has been properly cleaned away.
First do not try to charge or to turn on your phone and then remove the battery as soon as possible to prevent any further damage. Even if the phone is off, there is still power available at various points on the systemboard. The phone’s power on/off button is not a power isolating switch. Think of the phone as being in an extremely low power state when it is off rather than being off and disconnected from any power source.
Then you need to disassemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available from electronics parts stores) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is <70% IPA, 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 concentration (%) 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 boards. You will also have to remove any shields that may be covering some components as the water may have got in under them as well. Also disconnect any flex cables and clean the ends of the cable as well as the connectors that they were plugged into.
Hopefully after you have done all this the phone might possibly work correctly again.
If after properly cleaning the phone, the touchscreen still doesn’t work, it may have to be replaced.
Here’s a video that may help with this. Replacement touchscreens (digitizer) are available online. Just search for Galaxy SM-G531H digitizer to get results for suppliers that suit you.
If this process seems too daunting, take your phone to a reputable, professional mobile phone repair service, experienced in water damage repair and ask for a quote for a repair.
If you decide to do this, do it sooner than later. It’s not going to get any better by itself.
