Zero.
It was irritating at the time, but remembering it is funny. I'm not sure what made it start glitching, but it was doing so much random goofy stuff, mostly graphical glitches, and then it sent that text and died. I happened to have spare phone of the same model sitting around, and I was able to switch to it easily with my phone service. It didn't even last a month before it glitched itself to death as well, though not nearly as dramatic as the first one. I had a third spare one, but naturally avoided it and bought a better quality model instead.
