The Google Nexus range of devices come with a stock version of Android out of the box anyway, so many people do not understand why bother with installing a custom ROM on the device. We can tell you that there are still plenty of reasons. The main reason to install a custom ROM on any Android device is actually to update the operating system and not to run a stock version of Android — although the stock experience is enticing and is still one of the more popular reasons. But the fact is that for as long as our smartphone carrier networks refuse to update our operating system as our devices get older, the number one reason why anyone looks in the direction of a custom ROM will likely always be to check out newer Android software updates.

These are the best custom ROMs for the Google Nexus 7 2012 tablet so you can update your Android operating system and run newer software instead of your old version:

Google Nexus 7

Harmony ROM:

The Harmony ROM is the latest built custom ROM for the Google Nexus 7 which is based on Android 4.4 KitKat. The Harmony custom ROM is based on the CyanogenMod 11 ROM for performance and features.
