dropped into water?

"Hi,

As you know liquids and electronics and electricity are not a good mix.

The impurities in the liquid 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 process starts immediately and continues until it has been cleaned properly

First do not turn on your phone and then you need to remove the battery as soon as possible from the phone to minimize further damage.''

Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ to remove all traces of corrosion and water. Do not use ""rubbing alcohol"" as in some cases this is only 70% and is not as effective. If you do check the label to verify the amount

Here is a link that in general, describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the board.

Hopefully after you have done all this the phone might possibly work correctly again.

Here is a link to a video that shows how to dis-assemble your phone, which may be of some help.

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."

"Hi @muggiestevens77,

Use the directions in the Chosen Solution (see above) to try and fix the phone.

If your phone is not a Galaxy J7 Prime, search for your model phone in the ifixit search box (top of page) to see if there is a repair guide for it which will help you to dis-assemble the phone."

I disassembled phone, left it that way for three hours. Dried off parts with tissue. Put in a container of rice and made sure lid was on tight. It was in the rice for 8 hours. I put the phone back together. Now the phone works fine. No issues.
