Locking More Than The Lock Screen: Top Security Apps For The Smartphone


Location Service

Before adding any apps, it's a good idea to know what a device can already do right out of the box. Devices running Android 4.4 Kit Kat or above come with Android Device Manager, which constantly tracks device location and can plot it on a Google Map. It also can ring the phone at full volume (even if it's silenced), lock the screen and/or perform a factory reset (erasing all data). Apple's devices have had similar capabilities for several years.
