You no longer have to give up some of the Moto Xs voice commands if you want to rely on security codes. An update to the smartphones Touchless Control app lets you speak a PIN code to unlock the device; as long as youre not worried about eavesdroppers, you can check private messages without poking at the screen. You wont even have to unlock the phone as often as before, since the upgrade expands the range of Google Now voice instructions that work while the handset is sleeping.
