Update to Motorola Assist allows you to send a text using your voice
An update to the app includes a very useful feature. Now, in addition to listening to your phone read you your texts, it will allow you to send a text using your voice. This way, your messages get out without you having to divert your attention from the road. In addition, the update improves how well Motorola Assist detects that you are driving, using Bluetooth. And while you are driving, Motorola Assist will now launch your favorite music app.
The Driving Mode capabilities are available for the Motorola Moto X, Motorola DROID Ultra, Motorola DROID Mini and the Motorola DROID MAXX. The update is waiting for you at the Google Play Store.
