When the Nexus 5X and the Nexus 6P were announced, the phones were thought to have come with a double twist feature. Basically what this means is that by flicking your wrist twice, you will be able to launch the phone’s camera without having to press any buttons or turn on the screen.
This is a feature Motorola has incorporated into its phones. However before you start flicking your Nexus 5X and 6P handsets, Google has since confirmed that the feature is no more. Qualcomm had initially published a post on its blog claiming that the feature was part of the phone, but they too have since updated their blog to reflect the changes.
According to Qualcomm, “The feature to launch the camera via double-twist of the device was replaced by double tap of the power key.” While Google did not state why they decided to discard the feature, they did tell the folks at Android Police that they were initially looking at double twist or double tapping the power button as camera shortcuts, and ultimately the power button feature won.
We’re not sure why, but perhaps Google doesn’t want phones flying out of the hands of its users. Basically what happens now is that if you want a quick way of launching the camera without turning on the screen, you can just double tap the power button of the phone to do so.
