@ninamarie , Nina, If phone did not experience liquid or physical damage, unresponsive screen may either be caused by a glitch in the firmware or hardware and can be fixed by factory/hard reset according to the forum link #1 below. If after reset still not cooperating probable defective screen/digitizer or loose/bad plug/wire connection. Clean with a Qtip dampened min. 90% Isopropyl Alcohol and make sure all connections are seated well. You can use the links below to disassemble your device and clean the cable connections and reseat them to make good connection and try phone. Still a problem probable defective screen/digitizer replacement required. Link #3 is a replacement screen assy. which you can also do a search for better pricing perhaps. Good luck.
I hope this helped you out, if so let me know by pressing the helpful button.

Putting a wet phone in rice is one of the worse things one can do! While it is true that rice will also cause a film to develop on the phones circuit board; which will in turn cause circuitry interruptions. For example, you're in the middle of writing a text message, and all of a sudden your screen has a minuscule burp, and your text message is lost.
Proper treatment for a phone that has been dropped in water is to dry it as best you can with a towel. Then place it into isopropyl alcohol to dissipate all water. Re-dry it with a towel. Then preheat your oven to 250° next TURN OVEN OFF, and lay your phone in the declining heat of the oven. repeat this process until the phone is thoroughly dry.
Now your phone is as good as new! Turn it back on and once again use it.

A shop vac is also another great way to dissipate moisture in a cell phone!
