According to the Australian carrier Telstra, the Samsung Galaxy Note 2 will not be receiving the Android 4.2.2 update. Luckily there is no reason to fret though. The reason for this is because it will be skipping that version and will instead go straight to Android 4.3. Here's a quote from the carrier on the subject,
Although this has not been officially confirmed by Samsung, we have been hearing rumors that several Samsung devices will go this route. It's great to see a third party pseudo-confirmation of this. We will keep you updated as soon as it becomes official!"Samsung have elected globally to skip the 4.2.2 update for this device and will instead go to a newer version of Android. No schedule has been provided for this update."
