As just announced on Motorola's official blog, the company will begin rolling out Android 4.4.3 KitKat to unlocked Mot X, G, and E owners this week. Motorola has made a point of rapid updates since it was acquired and subsequently sold by Google, with Punit Soni acting as the public face of Motorola's software update team.

This update will be rolling out to unlocked (T-Mobile) Moto X owners, the unlocked Moto G (including the new and old 3G variants, as well as LTE the version), and the Moto E. This does not include the AT&T, Verizon, or Sprint Moto X, or the Verizon prepaid Moto G at this time. Those devices must go through carrier certification, though Motorola has historically been quick to update them relative to most other carrier-branded Android devices.

The update to 4.4.3 brings a few things, as detailed by Moto below:

Motorola users will also enjoy:

  • Improved camera image quality for Moto X including better consistency of exposure, more realistic flash coloring, and improved photos in low light conditions using front camera.
  • For Moto X and Moto G, pausing for video recording with a convenient pause/resume button on the viewfinder.
  • Motorola Alert in this update for Moto X and Moto G users. This new app helps give peace of mind by sending periodic messages to the contacts you choose.
