My wife's phone (Kyocera Torque with Android 4.1.2 on Sprint) received a bunch of updates, after which she can no longer get battery percentage level. Instead she gets a message saying "Unfortunately, Settings has stopped" or something like that. Even when I go to menu > System Settings > My Device > Battery, it gives the same error message, though other selections there work normally (e.g. Storage). So for now, the only battery level indication she has is the tiny little green partial battery in the status area, right side of top bar. At least that seems to be working roughly accurate.
