Ok so I ran into an issue here I've never had before. While I was using my phone, it rebooted on me. Not all that uncommon, but this time, after it turned off, it started vibrating and the camera LED started flashing on every vibrate. I've never seen this before. Holding the power button did nothing, and I had to pull the battery. However, this still didn't solve the issue. As soon as I put the battery back in, it would immediately vibrate, flash the Samsung logo, and then nothing. Holding the power will not do anything. Plugging the phone in for charging will just make it continuously vibrate every second.
I'm really stuck here. This is my only phone and not much idea what is going on. I have not changed anything on my phone in months. I'm somewhat led to believe this is the stuck power button issue, since it will immediately vibrate as soon as I put the battery in. But it would seem odd as I didn't touch the power button when it originally went into that odd LED reboot sequence.
