Locking the gizmo is cinchy: Press and release the Power/Lock key. The display goes dark; your Android is locked.

 The device spends most of its time locked. The gizmo still works while locked; email comes in, music continues to play, alerts bleep, and alarms clang. Phone calls arrive. Yet while the device is locked, it doesn’t use as much power as it does when the display on.

 Some Androids may not turn off the display while they’re locked. You may see the current time and notifications displayed, albeit on a very dim screen. This feature doesn’t impact the device’s battery life, and in many cases this setting can be changed if you don’t like the always-on touchscreen. See Chapter 21 for details.

 Press and release the Power/Lock key to lock an Android phone during a call. The call stays connected, but the touchscreen display is disabled.

  Locking doesn’t turn off your Android.

 The phone or tablet locks automatically after a period of inactivity, usually 30 seconds. You can set another timeout value, if you like. Refer to Chapter 21.
