BBC - Aug 9 - Android Pie, Google's latest version of its mobile operating system, has been released. One of the new software's headline features is its new Digital Wellbeing controls. These are in part a response to criticism that smart devices can be "addictive" and disruptive to our sleep patterns. Users can see how much time they spend on their device, with a breakdown of the hours and minutes dedicated to their most popular apps. Timers can then be set to limit usage of specific programs. When the limit nears, users get a warning - and when it is reached the app's icon becomes greyed out to prevent it from launching. The lockout can, however, be overridden.
