If your teenager  has dropped their cell phone in water or toilet and it won’t work ,  remove the battery and put the rest of the phone in a bowl of dry rice for an hour or even a month. I have a Teenager who is notorious for dropping their phone in the toilet.  After the purchase of a smart phone, and the destruction of an iphone, I stumbled across this tip from my friend Peggy from church.  I bought another Iphone for the teenager for christmas from another friend for only $50.00 which the teenager has paid us back for the other phones.  But to our amazement the old iphone started working.  Now the younger teenager has an iphone also.  :O)  Thanks Peggy
