But if the phone has less assessment than previous ratings, or no assessment, you should prepare for the bad thing if it is exposed to water in any way, so instead of trying to save the phone when it falls into the water in conventional ways, such as: shaking it hard to try to get the water droplets inside, here's the right way to do it.
1- Extract the phone at full speed:
After the phone falls into the water, take it out quickly, the longer the phone is in the water, the more likely it is to be damaged, then turn it off immediately, and don't try to press any of the other buttons or touch anything, just turn it off.
2- Quickly remove the phone battery:
Remove the battery quickly if the phone supports a removable battery, in order to prevent power from the device as quickly as possible to prevent the possibility of any short circuit, as some smartphones, such as: Samsung, Nokia 1.3 and some other smartphones allow you to remove the battery, while most modern smartphones come with a non-removable battery that can essentially be powered by Ingress Protection's water and dust resistance at a high rating rate.
3- Do not dry the wet phone with the dryer or put it in the oven:
Heat can damage the microelectronics components inside, instead quickly clean the phone with a dry cotton cloth, and make sure the water does not enter the charging port, SIM card slots, MicroSD or headphone jack.
If you notice that there are still drops of water in the outlets, try to dry them using the compressed air can but with caution by directing little air and quietly towards these outlets.
4. Let the phone dry completely before using again:
Do not try to use the phone after wiping the water off it or if the water drops are gone, instead leave it to dry completely, as you can wrap the phone in a dry cloth and put it in a bag with rice in it and then close it for 12 to 24 hours, where the rice helps absorb the moisture superbly.
Use of specialists:
If you find that the phone is still wet even after you have used the previous steps or that the phone is not working well, it may be better for you to turn to a maintenance center for help, as some retail stores offer dedicated services to fix smartphones that have fallen into the water by using tools specifically designed to draw water from them.
How to be prepared in case the phone falls into the water:
At times, it is good to be prepared for these cases, and the best way to do so is to keep packages containing white granules that you find in new bags, new shoes or electrical tools - known as Silica, where they help absorb moisture quickly and efficiently.
You can buy them in bulk, and then the next time your phone or any family member's phone falls into the water, simply put this phone in an airtight packaging containing these granules and leave them for a day or two to absorb the moisture in the phone.
You can also buy custom bags, such as: Nine Lives Wet Phone Fix, or Nanoflow X which is a ready solution you can keep at home, all you have to do is put the phone in the water inside this bag and close it tightly, and then wait 12 to 24 hours for your phone to dry.
