In our review of the Moto X, we determined that while its ClearPixel camera was decent, its performance was hit or miss. Fortunately, Motorola has taken a lot of feedback and has cranked out a software update with improvements to the camera's performance, specifically in the areas of exposure, color accuracy and focus speed. The refresh, which is so far getting pushed out to T-Mobile phones -- we expect it to roll out to other carriers as soon as each one is done testing the new firmware, though nothing is currently confirmed -- appears to make a rather substantial difference in several scenarios, such as reducing noise in low-light and eliminating haze in outdoor shots. Anandtech's Brian Klug had the opportunity to take the updated shooter for a test run and declared it to be "nothing short of the biggest [improvement] I've ever seen come across in an OTA update."
In addition to the camera improvements, Motorola also threw in a few other enhancements as well. Users who have downloaded the update should expect increased Touchless Control accuracy, a fix for the choppy audio issue some have experienced in voice calls and an improvement to Moto Assist as well.
