Android currently reigns supreme in the global smartphone arena, underscoring the fact that the Google platform has been generating satisfaction among the hundreds of millions subscribed to the system since its inception.

The ecosystem's vast apps collection plus the attractive and powerful devices make for Android's main appeal, experts said.

But there's more to discover and to love about this mobile OS, the latest version of which, the JellyBean 4.2, further highlights its rich and powerful features being rendered on popular Android handsets such as Samsung's Galaxy S3 and Galaxy Note 2, HTC's Droid DNA, LG's Optimus G and Google's signature smartphone, the Nexus 4.

What follows below are Android functions sparsely used but could further enhance users' interaction with the Google environment, in aid of course of their preferred handset.

Camera attributes that come with Android phones range from decent to near-superior, experts said, but beyond the tech specs Android camera is blessed with interesting characterictics that will surely make 'shooting sessions' more enjoyable.

In Galaxy S3 for instance, the camera can be launched from the Lock Screen, according to Yahoo blog Upgrade Your Life. To enable this, follow this route: Settings>Security>Lock>Screen Options, then check Camera Quick Access.

To try out, press and linger on the S3's Lock Screen then rotate the device 90 degrees to bypass your way into the camera app.

Note, however, that this feature is unavailable on older Android versions but there are app solutions on Google Play store. One of them, according to Upgrade Your Life's Becky Worley, is Widget Locker, which allows users to personalise their handset's Lock Screen including of course on ways of launching the camera.

Android camera is also programmable for voice control and on the side, users can record pics, artworks and almost anything beamed on their screen through the Screen Capture function, Ms Worley said.

Android offers provisions too for users to take control of their handsets thanks to the system app Task Manager. When launched this tool shows the running applications and presents to users the choice to kill apps they don't need at the moment.

This is Android's way of battery and RAM management, which is accessible in most Android smartphones by pressing down the Home key, Upgrade Your Life said.

And when your phone suddenly goes funky and forced reboot has become essential, simply hold down on the Power button until the device restarts, hopefully correcting its previous erratic behaviour, Ms Worley said.
