When Google commenced rolling out the latest update of Android 4.4 Kitkat OS - the 4.4.1 - to in-house devices, such as Google Nexus 5, Nexus 4 and Nexus 7 LTE (2013), the Wi-Fi version of Nexus 7 was left out.

It has been reported that the Nexus 7 Wi-Fi version is yet to receive the OS update Over-The-Air (OTA), though users can install it manually.

If the users are comfortable with flashing the system recovery files etc, then it can be done with a few simple steps. But if the users are not confident enough, it is recommended that they should wait for the OTA update. The OTA update is speculated to happen soon enough, since we know that the factory image is available for download.
