Android 4.4.4 is right now being pushed out for the Motorola Moto G in Brazil and India. The Motorola Moto E is receiving the same update in Brazil, France, Canada and the Asian Pacific market. In the U.S., Motorola says that it is in the process of updating the Motorola DROID Ultra to Android 4.4.4.
No mention was made of the Motorola DROID MAXX and Motorola DROID Mini, both of which are supposedly part of a soak test of Android 4.4.4 being sent out to members of the Motorola Feedback Network. Once the test is concluded, both models will be added to the list of the manufacturer's handsets that are receiving the Android 4.4.4 update.
