Within this last week, my phone started crapping out. The screen would spontaneously go black and it would repeatedly vibrate on pulse. Eventually, it would restart. This started happening with increasing frequency. This prompted me to go get a new phone, which I had been thinking about lately anyway. The old one doesn't seem to want to run for more than 5 minutes before it restarts again. Still not sure what's wrong with it... my best guess is that the battery doesn't sit right anymore.
But anyway, new phone! S5!
