Google has started rolling out Android 4.4 KitKat updates on the Nexus 7 2012's and Nexus 7 2013 WiFi-only versions. Some users have already received the update, but one week after Google's announcement, the Nexus 7 Android 4.4 KitKat update is still missing for some.

Google debuted the Android 4.4 update on Oct. 31, just a few days before the Nexus 5. However, Google remains mum on the release dates of udates for Nexus 4, Nexus 7 and Nexus 10. On Nov. 12, Google announced the start of Nexus 7 WiFi and Nexus 10 Android 4.4 KitKat update distribution. However, even though all are aware that the update process could take more than a week, a lot of Nexus 7 users still haven't seen the OTA updates.

Usually only a few are left without the Android 4.4 KitKat update after the end of the first week, but Google's Nexus Google+ page has been receiving many complaints, as Nexus 7 users have already started asking for Google's reason for the delay.

Fortunately users with a bit of know-how have a way to get the software update, as users could just install software themselves. Owners can pull the updates from Google's servers directly, so they could manually install it and skip the OTA. The Android 4.4 KitKat updates for Nexus 4 and Nexus 7 LTE and HSPA+ are also available via Google's developer site. Those OTAs will begin soon now that the Verizon Moto X Android 4.4 Kitkat update has already begun.

The manual update only takes four steps: downloading the OTA update directly from Google, downloading ADB/Fastboot files, putting the device into Bootloader mode and Recover mode, and transferring the file to the phone.

Android 4.4 KitKat has full voice control, faster multitasking and wireless printing. Moreover, the new caller ID system feature can make a guess at who an unknown number calling is with the use of businesses listed on Google maps. KitKat devices can also send documents directly to printers using the Google Cloud Print or HP's ePrint system. Quickoffice has also been redesigned to find files easier, editing documents and spreadsheets simpler.
