Motorola has been great lately at keeping their pretty tight to the AOSP vanilla Android standard, however they are not perfect when it comes to this and while they may be the cleanest OEM skin there are still bits and pieces of their firmware that strays from AOSP stock. There are plenty of roms available for the Moto G but the most popular rom seems to be the C-rom and for good reason. Not only does it bring full AOSP stock Android to the Moto G it also brings a good set of features to the device. Features include performance tweaks, Pie launcher, Holo, Appbar, Dark C-Rom theme, Active display, floating windows, Gesture anywhere, On The Go Mode, Animation Controls, Lockscreen notification, Implemented App sidebar, and many more features. This rom is stable and should present no bugs. To install this your device will need to be bootloader unlocked with custom recovery installed. Head to the link below for the download.
