Oh, Dave - I am SO sorry to hear this! The suggestion from Rus is a keeper! Rice does restore cell phones that have gotten wet.
My grandaughters have dropped their phones in the toilet and sink full of water - and the rice in a baggie with the phone, make them workable the next day!
Now, about your injuries - did you have to get stitches in your knee? I hope you had a doc check you out - to make sure that no injuries are serious!
Prayers for you, FRiend!
Going to the Dr on Thursday. Just the surface skin was pealed off. Sutures wouldn’t work on that injury. Meanwhile my foot and knee area are pretty bruised and sore. Put ice on the foot today. Also my lumbar area is more painfull.
