A Twitter user named Romario Fernandes posted an image that shows the 'Android 4.4 System Update' notification on his Nexus 7 Wi-Fi+3G tablet. Fernandes said on Twitter, "Just got the OTA for my nexus 7 Wifi+3G."
The purported Android 4.4 system notification on the Nexus 7 (2012) tablet reveals that the update is about 186MB in size and can only be downloaded via Wi-Fi. Further, the notifications said "via Wi-Fi only until November 23", which suggest that later it might be downloaded over 3G network. The update notification also includes some new features namely colourful Emoji keyboard, and new Print feature.
The Android 4.4 KitKat iteration brings some new features to the Nexus 7 tablets such as a new translucent menu bar, which is located at the bottom of the screen; new Emoji keyboard for emoticons in the native Google Keyboard; unified Hangouts messaging app; smarter Google Now integration; better support for cloud printing; and new Quick Settings notifications menu toggles include a 'location settings' toggle.
Earlier on Friday, the Nexus 4 reportedly started receiving Android 4.4 KitKat update in India. As of now, there is no official word from the search engine giant on the Android 4.4 rollout for both Nexus 7 tablet (Wi-Fi+3G) and Nexus 4 smartphone. But recent tweets suggest that Google might be rolling out the update in phases for the Nexus devices.
Earlier this month, Google officially announced the rollout of Android 4.4 KitKat for its Nexus 7 and Nexus 10 tablets (Wi-Fi only models), available OTA. The search engine giant confirmed the news via Android's Twitter and Google Plus accounts. Google had also said the Nexus 4 and Nexus 7 3G models would be receiving their update soon.
