Got my S7 wet - problem getilng it to boot

[jshaw42]

I was in the Caribbean for abut three minutes. Didn't realize I had the phone with me for a few more minutes. Dried it completely and everything was okay until I tried to charge the battery. After plugging the charger cord in and not seeing the battery charging, I took out the charger cord out and put it back in a couple of times until it showed that it was charging. Then I got this screen:
S7message.jpg
and it would not let me use any of the buttons to close the screen or anything.

I allowed the battery to fully drain then started a new charge. When it was fully charged, I powered down and took out the SD card just to make sure I saved the files on it. Then the S7, booted fine.

Then I powered down and reinserted the SD card and got the above screen again.
I am letting the battery drain again to see what happens.

Any ideas what I did wrong?

Have you moved any apps to the SD card before the dunking?

your first mistake was trying to use the phone period without letting it get thoroughly dry.

and there is ONLY ONE WAY to be sure that is done properly and that is with a vacuum chamber.

bags of rice are too slow, and ineffectual for deeply buried moisture.

There is a small chance, that it will still be usable if you use a vacuum to dry it out.
Harbor Freight and automotive supply stores all carry the cheap hand vacuum pumps with a small dial type gauge on them.

you can use almost anything for the container, a glass jar, a paint can, etc...
rig up a way to connect a hose from the container to the pump, pump it down to 26 inches of Mercury and keep it there for about 24 hours....

open the phone up, remove the battery, SIM card, etc....

If it is going to work at all, it will work when you take it out of the vacuum chamber.

Isn't the S7 supposed to be IP68 water-resistant? Have you checked with Samsung about warranty?

It was in the Caribbean Sea? For saltwater damage, you might be buying a new phone otherwise.

Thanks for all the suggestions.

AZg1500, one can not open the S7 to remove the battery without a great deal of work.

mikedt, I was aware to the water resistance of the S7 and hoped for the best.

Things went better than expected. The S7 still works perfectly after using a hairdryer. I damaged the SD card somehow (probably inserting and removing the power cord to quickly).

Copied everything from the SD card and reformatted. Copied music, docs, etc. back to the SD card and have had no further problems.

My advice would be to take time to let things happen rather than react in panic mode as I did.

For one thing, all of this isn't applicable in the S7. It's already water proof and sealed. All you have to do to it is wipe it down, let it dry for a couple of hours, then it's good to go. Often times you can just use it again as is.
