Cons
Con Requires Android 4.4+ (KitKat)
The Google Camera app system requirements do require Android 4.4 (KitKat) or better, as a result this does leave out a lot of older phones and tablets. The app does take advantage of features of higher end phones, so you will need to upgrade if your device has an older version of Android.
Con Limited device support - Only available for Google Nexus and Pixel
In 2016 they stop providing Google camera for non google devices. You can download APK and install. But it crashes and most likely the video camera will not work.
Con Photo Sphere does not work on all CPUs
For example, Android-Lenny 4.4 does not support this.
Con Potentially confusing amount of options and settings
Con Cluttered Interface
The interface can be somewhat clunky and difficult to use
