Never had any problems, but just today, my phone just shut off. When it shut off, it kept vibrating, just small pulses over and over until I took the battery out. When it shut off, it had 100% battery, so I put the battery back in hoping it would turn back on. The samsung logo/boot screen came up, then it just shut off. It does this repeatedly. I tried putting it into recovery so I can reset it, but it doesn't boot into recovery or download mode.
Strange things: Whenever I hold down the volume down key, it does the vibrating pulse thing until i take my finger off it. And when it's on the charger, it does the vibrating thing the whole time until I unplug it, even if the battery isn't in it.
