Nokia Lumia 925 getting "Peek" feature to quickly see the time15
As with any other phone, pressing the power button will bring up the lockscreen on the Lumia 925, and Nokia has added an option so you can simply double-tap the screen to also bring up the lockscreen. But, there is also a new option, which Nokia is calling "Peek", which brings up the "Glance" screen by waving your hand in front of the display. Currently, bringing up the Glance screen just shows a black screen with the time as well as a notification showing if your phone is in silent/vibrate mode.
There isn't much to it now, but this could easily be a good spot for some quick toggles, like silent/ring mode, airplane mode, WiFi, and Bluetooth toggles. Although, it's unclear if that is the plan for the future.
