Looks like the Nexus 6 is eliminating the need for you to press the Power/Lock and Unlock button when you pick it up from your desk. According to Android Police, the Motorola-made Nexus 6 has an Ambient Display setting that will wake the screen when the device is picked up or when notifications arrive. This isn’t really a new feature as Moto X already carries a similar feature. However, the good news is Ambient Display might be part of Android 5.0 Lollipop update. So, there could be more Android devices that can wake this way.
