19. A non-transitory computer readable storage medium storing one or more programs, the one or more programs comprising instructions, which when executed by an electronic device, cause the device to: while the device is operating with a first setting in a first state, detect, at a first time, a change in settings of the device to change the first setting from the first state to a second state that is different from the first state; while the device is operating with the first setting in the second state, receive, at a second time that is after the first time, a user input that corresponds to a pattern of user behavior, wherein the user input is a user voice input; in response to receiving the user input: compare the pattern of user behavior to a plurality of predefined conditions that, when met, indicate that the user is having difficulty with operating the device, wherein a predefined condition of the plurality of predefined conditions includes the user voice input containing one or more predetermined words associated with user difficulty; in accordance with a determination, based on the comparison of the pattern of user behavior to the plurality of predefined conditions, that the device changed the first setting from the first state to the second state within a predetermined time period prior to receiving the user input, restore the first setting to the first state; and in accordance with a determination, based on the comparison of the pattern of user behavior to the plurality of predefined conditions, that the user is not having difficulty with operating the device, maintain the first setting in the second state.
