This is one of the worst mistakes you can make after dropping your phone in water. Putting it in the cold of a freezer is a definite no, just like wrapping it in a towel and thinking that will remove the moisture from inside.
3. Don’t rush your decisions:
You don’t want to make a bad decision — but you also shouldn’t wait too long to act. Up next, we’ll look at the correct steps to take. Otherwise, the damage could become permanent and irreversible.

Steps to Save Your Phone
Fortunately, there are things you can do to prevent your phone from being permanently damaged:
1. Turn off the phone:
The very first thing you should do is power off your phone, even if it seems like it’s working normally.
If you see water droplets on the surface, it’s best not to move it around too much. You want to avoid letting any water reach the internal components.
2. Take the phone apart:
Next, carefully remove the SIM card, battery (if possible), and SD card. Then gently remove any excess water or liquid.
Be extremely careful not to use tools like screwdrivers, as opening the device improperly could void any warranty.

3. Use the rice trick:
Once your phone is turned off, a widely recommended trick to absorb moisture from the internal circuits is to use uncooked rice.
Place the phone in a bag filled halfway with rice, making sure the phone is completely covered and the bag is sealed. Then, leave it in a dry, moisture-free place.
It’s best to leave it there for about 48 hours. The key is to let the rice absorb all the moisture. After that, check to make sure there’s no remaining water inside. If there’s still any moisture, put the components back into the bag and repeat the process.
Finally, if your phone still won’t turn on after this, the only remaining option is to take it to a repair technician.
