Despite all of Sony’s recent developer-friendly awesomeness, a few relatively recent devices have fallen through the cracks and have been left without official Android updates. While most of these devices generally have found vibrant aftermarket development communities that have filled these gaps, this isn’t the case for every device.
One such instance is the Sony Xperia Ion, a device that was only officially updated to Android 4.1.2 and never received stable aftermarket builds of Android 4.2 or 4.3. Now thanks to hard work by XDA Senior Member MrGezz and Recognized Developer RaymanFX, a nearly fully functional Android 4.4 KitKat build has appeared for the device. This release comes in the form of an unofficial CyanogenMod 11 release, and it builds on work originally created by FXP for their CM10 builds.
There are currently two known bugs: The LED indicator does not light up when charging, and the battery percentage does not initially show properly in the status bar. The first bug is only a minor inconvenience, as the battery still charges even though the light does not come on. The latter, while annoying, has a functional workaround that is accomplished by changing the battery status style in CM settings.
If you’ve got an Xperia Ion and want to give KitKat a try, head over to the original thread and get in on the action.
