Ip68 with S21 Ultra ???

[Al-001]

According to menaul , Galaxy S21 Ultra supports standard of ip68, unfortunately, my daughter's S21 Ultra doesn't power up anymore after dropped into water for about 2-3 minutes, 

With ip68 how long can the S21 Ultra be in water?

It's actually ip68 (ingress protection), and it means that With an IP68 rating, they are water RESISTANT in fresh water to a maximum depth of 1.5 metres for up to 30 minutes, and are protected from dust.

That's water RESISTANT, NOT waterproof! 

No idea what cp15 is in relation to Android.

Thanks for thd correction, yes, it's ip68. But my daughter only dropped the phone in sea water with 1 feet deep in about 2-3 minutes, and the phone is totally dead.

Sea water is different, and the ip68 rating refers to fresh water only. 

If this happened recently, put the phone in a baggy half full with uncooked, raw rice, ie: not instant rice, but something like basmati rice over night. 🤞🏻

Yes, we did the exact same at the resort, which provided rice per our asked. Unfortunately, it doesn't work. After coming back to Toronto, we went to samsung Store, and technicians do not recommend fixing it at all. Sadly, We have to buy a new S23 without a trade-in option.

I would rinse the usb port with rubbing alcohol.
I have seen lots of pros say rice is a waste of time. The alcohol will dry out the water.
The ip68 rating is defeated if there's ant cracks in the back glass or anywhere else or if the rear glass has ever been removed.
Sorry for your trouble.

Actually, if someone is going to use alcohol, they should be using isopropyl alcohol and not rubbing alcohol, as rubbing alcohol also contains water. 99% isopropyl alcohol contains virtually nothing else, while rubbing alcohol can contain as much 30% water. 

Silica Gel packs are also a good option. 

You are correct in saying that if the device has any cracks, it would likely no longer maintain it's ip68 rating & protection. Samsung stores are also in the business of selling new devices, so I'd possibly take the phone to an independent Samsung authorized service center.. for a 2nd opinion.

Actually dipping the device in fresh water is better than nothing. I would use any type of alcohol readily available is better than nothing. The alcohol will evaporate any water and hopefully rinse away residues of salt.

My daughter's s21 ultra is in pretty good condition as like as a new one. By following instructions on how to open the back cover, I opened the back cover and ensured it's already dry. Unfortunately, it doesn't power up and can't be changed anymore, either.
Thanks for your kindness.

Happy New Year! I wish you and your family keep safe , healthier, and wealthier in the New Year!
