I gave my son my Nexus 7 16 GB and bought a 32 GB at Wal-Mart. Perfectly sealed in the package. When I powered it on, it didn't prompt me to sign in to a Google account. It also has the apps AtCmdSender, Dev Tools, GPS Test, Log Tool, Log Tool 3.1.0, NFCReader Test, and WLan RF Test Tool. The model number states Full Android on Grouper. Sooo... do I just need to return it?
