If you’re a Galaxy Note II owner, you’ve been probably wanting to get your hands on some of the new software features that debuted on the Galaxy Note 3, without having to actually upgrade your device. Some of those features should arrive on the Note II with the Android 4.3 update, but if you’re unwilling to wait and are okay with flashing custom ROMs, then you can get some of those software features right away.
A team of XDA developers have ported over some of the Note 3 features, such as Air Command, S Note, Sketchbook, S Planner, gallery, and more, to the Note II, by adding the necessary files to the pre-release Android 4.3 firmware that leaked for the device. These features are working well for the most part, though a few minor issues persist, such as the one hand operation feature working only for a few apps, Air View appearing twice in the settings, but these should be ironed out in the future with a few updates.
As always, flashing custom ROMs is risky, so make sure to take all the necessary precautions before attempting anything. The source link has all the details you need to get a taste of the Note 3’s software experience on your Note II, so go ahead and get right down to it.
