If you have an android phone you can set your ringer to quiet down when you pick up your phone. This feature is especially helpful when your phone rings at the office or in class. Sometimes it takes a while to silence a call but with this feature enabled all you have to do is move your phone and it'll quiet down. Just go to Settings > Sound & Displays > Quiet Ring On Pick-up.
Place the battery and phone in a zip-loc bag of dry rice and leave it overnight
Remove your phone from the rice and reinsert the battery
The rice should absorb small amounts of moisture that seep into your phone. If your phone was submerged in water for any length of time, say if it went through the laundry, the damage may be more extensive. If the rice trick doesn't work you may need to visit a service center and inquire about water damage repair.
