This update totally broke my settings! :-\
I just did the update and when I rebooted, the setting for apps and battery completely crash the settings. From what I understand, the update was to help with battery and it supposedly optimized the apps as it was installing. what a joke, now my new phone is trash, thanks T-Mobile. Don't worry I tried to reboot, do a complete shutdown and all that crap, still has the same problem. My phone was great before this and now I got the "battery settings crash" like on Verizon not that long ago with a number of their phones.
