If you thought that the Android L operating system released on 15 October by Google is all about the new ‘Material Design’ user-interface, think again. The number of security features available in Android L is pretty extensive.

So if you are planning to use the Android L OS (after receiving Google’s latest OS upgrade via the over-the-air mechanism) then you will benefit from having a smartphone/tablet that can not only do more but is also now much more secure thanks to the ‘kill switch’.
Kill switch works a little bit like a factory reset, and ensures that your phone does not get reset, without keying-in a password.

Together the factory reset protector and remote lock features form a kill switch combination, and add extra levels of security to your devices running Android L ‘Lollipop’.

Just imagine you have lost your precious Android smartphone and the thief has your expensive device in his hands. The thief resets your phone, before you could remotely find your device and lock it.

In such a scenario, Android’s remote find/wipe/lock features become worthless, as the thief has already factory reset your device.

This is where the latest kill switch combination comes into picture, and once this is enabled (optional for now) within your device, you get multi-layer protection.
