There is provided a mobile device comprising: one or more sensors; a plurality of additional sensors; and logic configured to: obtain one or more first data outputs from the one or more sensors when the mobile device is in a first state; obtain one or more second data outputs from the one or more sensors; determine whether there has been a transition from the first state to a second state, based on a difference between the one or more first data outputs and the one or more second data outputs; obtain one or more third data outputs from the plurality of additional sensors if there has been a transition from the first state to the second state; and compare the one or more third data outputs with stored data outputs obtained using the plurality of additional sensors in a third state of the mobile device, the third state being a state prior to the first state, thereby determining whether the mobile device is in the third state. |
