My Galaxy SII has just crapped out on me. Battery was pretty much fully charged today. Went to the movies this afternoon. Came out and sent a couple of texts. Heard a response to a text. It actually made the response a couple of times. Seemed like the first one was normal then briefly afterwards there was back to back tones like someone sent extremely short messages. Went to check the message and the phone was powered off. Tried to power on but it only shows SAMSUNG for a couple of seconds and then shows it again. There is a momentary flat line across the screen just after the second SAMSUNG logo. Then nothing.
I think I am out of luck but hopefully someone can help.
