The original Moto G is getting an over-the-air update to Android 4.4.4 right now. If you have the XT1032 mode, What are you waiting for? Open your settings Menu, update and start exploring the new Android 4.4.4!
A few users over on XDA noted the update, and one was kind enough to post the ZIP file. If your phone is still running the stock Motorola recovery partition, you can download and flash it right away, though any root-level modifications of the software might fudge things up. Motorola has posted an update notice (version 210.12.61) for “all US Retail users,” meaning that other versions if the phone sold in the United States might be getting 4.4.4 very soon as well.
Of course when it comes to updates, the current focus is on Lollipop. Motorola has committed to a Lollipop update for the original Moto G, including the LTE version, though predictably there’s no date. That may or may not include the customized models released for Verizon and AT&T.
