Google recently announced Android 4.4 KitKat alongside the new Nexus 5, but while doing so, the company dropped support for the Galaxy Nexus. The device is a couple of years old now, so Google’s decision does seem reasonable. The Galaxy Nexus still has the power to run KitKat, having enough RAM (KitKat requires minimum 512 MB RAM) and while the processor might be powerful enough too, there’s no support from TI, the SoC maker, possibly one of the reasons why Google decided against providing an update.
It would have been a good demonstration of KitKat’s efficiency had Google updated the Galaxy Nexus, and would have also acted as a message to other OEMs regarding supporting their devices, but unfortunately, it was not to be.
Fret not, though. XDA is a wonderful community, bringing together devs and enthusiasts alike. As of now, there are two Android 4.4 KitKat ROMs working, and there’s another ROM that’s going to show up any time now.
There are some graphical and UI glitches here and there, but the said ROMs are still in alpha, and more like a proof that Google could have tried to update it rather than turning a blind face, but anyway. Things should get a whole lot better as time passes, since the devs are constantly working to iron out the issues.
Note that these ROMs are for those who know what they’re doing, so if you don’t have an idea, read first. I cannot stress this enough. If you want to play with KitKat on your Galaxy Nexus, but haven’t flashed a ROM till date, go through the forums on XDA. Read as much as you can, then try and flash a CyanogenMod ROM first (most failsafe). If that seems alright to you, go ahead and give these two ROMs a try.
