An ``unlock`` episode is considered as the time between an ``unlock`` event and a ``lock`` event. iOS recorded these episodes reliable (albeit some duplicated ``lock`` events within milliseconds from each other). However, in Android there are some events unrelated to the screen state because of multiple consecutive ``unlock``/``lock`` events, so we keep the closest pair. In the experiments these are less than 10% of the screen events collected. This happens because ``ACTION_SCREEN_OFF`` and ``ON`` are "sent when the device becomes non-interactive which may have nothing to do with the screen turning off". Additionally in Android it is possible to measure the time spent on the ``lock`` screen onto the ``unlock`` event and the total screen time (i.e. ``ON`` to ``OFF``) events but we are only keeping ``unlock`` episodes (``unlock`` to ``OFF``) to be consistent with iOS.

Otherwise, it is defined as active status. One active/sedentary bout is a period during with the user is under ``active``/``sedentary`` status.
