did that work for you?
okay, take your time. Let me know if you need anything.
this sounds like the phone may have water damage, that is the usual symptoms. If that is the case then the repair will be very expensive. It will involve all of the main circuits and the main board in the phone. I am sure it can be repaired though.
do you have a local smartphone repair shop?
