Ever since ICS it's been a little wonky but very fast and mostly very satisfying. But, and it's a very big but. At least once a week my Maxx would spontaneous lockup and then reboot. Not sure what caused it, I couldn't make it happen. It started to crash every day and now several times a day. So I bit the bullet and FDR'd and only added the minium about of apps, (177 is probably too many.) Today it was running fast and snappy and then blam, not only a reset but a continual reset. Grrr, I got it to stop after a bit. and then it was fast and snappy again for about a hour and then. Stuck in a boot loop. Verizon store for sure.
