I came home and charged the phone (plugged in the USB cable), left it for an hour or so and tried to turn it on. I got a "spinning" black and white wheel (which is actually frozen). Next comes the grey image of an empty battery which doesnt show charging (filling with green) even when the phone is plugged in. The home, back, etc. etc. buttons flash white for a moment and the phone turns off. Try again, same thing.
I thought maybe the USB wast connecting or charging so i took the battery out and charged it on an external charger which shows that it is full. Put it in, same thing.
Tried hard reset but cant complete it because samsung logo screen doesnt come on, only "empty battery" image.
Phone doesnt show up on my mac. etc. etc.
I am out of ideas...
btw no kind of water contact or dropping.
I really hope someone has another suggestion or can point me in the right direction.
Thanks for reading.
