Problems started yesterday. First it refused to connect to computer via USB, then it didn't load battery using it's own charger and then I switched it off. The front leds didn't turn off so I removed battery. Then I put it back in and tried to reboot. No any sign of life and seems bricked to me. Battery still had about 30% power left when I turned it off. Strange here is that I haven't rooted it, so why it does this and how to fix it?
at least you didnt root it as you wont have any problems to have it checked to samsung service center...make use of your warranty
