Motorola’s VP of Product Development, Punit Soni, has already said camera improvements were coming soon to the Moto X and it looks like the company is indeed working on them. An XDA forum member posted files from Android 4.3 for the Moto X on Friday and says that although the device runs a little slower than it did on Android 4.2.2, the camera seems improved.
Android Central, which originally found the XDA posting, notes that if you have an unlocked Moto X, you can install the software yourself. I wouldn’t advise it because it was dumped from a test phone. Clearly, the software update is still a work in progress. It’s good to see that progress, however: The inconsistency of image quality from the camera is the phone’s Achilles Heel based on my usage.
