Moto X camera capabilities was never really good enough compared to the competition. A software update did help in improving things immensely, but the camera software was still partially broken. The touch to focus feature in the Camera app, always focused in the centre, and did not expose the images accordingly.
This led to out of focused, blurry images, with lost details. Thankfully, with the KitKat update for the Moto X, Motorola has tweaked the Camera app to greatly improve the touch to focus capabilities of the handset.
As shown by Jerry Hildenbrand of Android Central, the Camera app in KitKat has a new touch to focus mode that needs to be activated manually. The user can then drag the reticule anywhere on the screen to focus, and the camera app will not only focus on the selected subject, but also set the exposure level correctly.
While this small change will not make the Moto X camera stand out from the competition, it will greatly enhance the overall image quality and color, preserving your memories.
