March 28, 2017: AT&T sends out some update. Screens displays update is complete. Phone reboots and, and, and...... nothing! Bricked phone. AHHHHHHHHHH! I had it charging so after the phone stayed at the AT&T globe logo for an inordinately L-O-N-G time, I unplugged it and attempted a hard reboot. Nothing! I started hyperventilating. I got up and got some ice water (to pour over my head and stop the volcanic eruption about to take place). But when I came back, why, the phone had rebooted again and it was fine. Good thing, too, I was ready to race over to AT&T and give them a piece of my mind. As near as I can tell, after the mess, it was a security update because the phone is still Android 7.0.
