Important Notes

The first tablet from Google, the Nexus 7 is unlockable by the user and is available in 16GB and 32GB sizes (previously, there was also a 8GB version available). The price of $199 for the smallest variant was a big advantage, also having the strong NVIDA Tegra 3 quad-core processor and the 416 MHz twelve-core GPU in mind.Please note that you need to have Android 4.2.2 (exactly) on your Nexus 7 in order to be able to use LuneOS !
