The online-only T-Mobile variant of the Moto X was the first to get the surprise update, followed quickly by Sprint. Now AT&T is next out of the gate, leaving Verizon trailing behind. We probably could have pre-written this, and maybe we did. You'll never know.
This appears to be mostly the same update that hit the other devices, but AT&T changed up the wording of the changelog. Here it is for your consideration:
- Enhanced camera auto-white balance performance and color accuracy.
- Improved exposure when taking photos outside or backlit, and improved clarity in low light.
- Faster touch-to-focus time and reduced unnecessary refocusing in low light or scenes with continuous motion.
The update notification should pop up on all devices in short order, or you can head into the settings and manually check for the update. Well, AT&T says that, but maybe it will actually work. You better start checking very few seconds just to be safe.
