Dropped the mobile phone in water?
The video above has some tips on things you can do to save your wet cell phone from damage due to water.
First remove the phone’s battery and the SIM card that may have your contacts data and the call logs (the good news is that SIM cards can often survive water damage).
Dry the phone with an hair dryer and then put the phone in an air tight container with some silica gel and let it dry. It might work as the silica crystal will absorb the water moisture.
