My cell phone went through the washing machine. help!?

it only took me 2mintues after i started the wash that my cell phone was in my sweaters pocket. took the battery out and put them both in a bag or rice overnight. this morning i stuck it in the freezer for 15-20 minutes. then i put it back in the rice bag to thaw out. i was hoping that when it thawed the water from under the screen would get soaked up by the rice. it mostly worked but theres a tiny spot in the middle still there, and when i turn it on the screen is white with the LG logo. i dont if i should leave the phone on untill it works or what ?
