The Samsung Galaxy Note 2 is a pretty powerful device, but its title of "flagship" has been recently taken by the newer Note 3. As such, this will also affect the time in which the Note 2 will receive the latest Android KitKat update. The Note 3 is on the priority list at this point, whereas the Note 2 will be a latecomer.

Fortunately, you can always rely on the developer community to deliver solutions to your problems. In other words, if you want to experience the Android 4.4.2 OS on your AT&T Samsung Galaxy Note 2, you can do so by using a custom ROM. OmniROM has recently started launching nightly builds for the AT&T Note 2, and this guide will allow you to install the latest OmniROM on your device.

Please note that this release is not an official Android / Samsung update. It's a custom ROM and it's not final, hence the "Nightly" title. Nightly builds are not really stable, but they are developed on a daily basis. As such, a bug today can be fixed tomorrow with a new release.
