save a wet cell phone

Firstly, it is a good thing that you took out the memory card, SIM and battery from the phone immediately after getting it out of water. It is advisable that you should take the phone to nearest Samsung authorized service center, so that it can be repaired. But before that, there is a home remedy you can try which was also found very useful in the past. Take a bowlful of uncooked, dry rice and dip your mobile inside the rice on bowl. Be mindful that the phone is completely covered with rice and also make sure that the rice is dry enough before that. Keep the phone on that position for some 3 to 4 hours and take it back. Affix your SIM and battery on the phone and check if it is working, and most likely it will. Dry rice is a great desiccant that absorbs a lot of moisture, and thus works perfectly for absorbing water droplets from your phone. If the phone still does not turn or or showing artifacts after turning on, it is better to give the phone to a service center.
