A new chart from Samsung has revealed that the company is currently testing the Android 4.4.3 update for its flagship devices like the Galaxy S5 and the LTE-A variant of the Galaxy S4. Another chart has revealed the availability of the Android 4.4.2 update for some older devices such as the Galaxy Grand (both models), the Galaxy Note II LTE and the Galaxy S4 Mini. (lsu79.org)

As for the upcoming Android 4.4.3 update, there’s not much info on what this new version of Android will bring to the table, but it has been rumored that Google could introduce redesigned navigation keys at the bottom with sleeker looking icons.

There’s obviously no confirmation of the feature, so we’re holding onto it with a grain of salt until the I/O event next month where Google is expected to make the update official. It’s a bit out of the ordinary for OEMs to get the source code of an upcoming Android version even before it’s made official. Perhaps it’s a sign we’ll finally see updates being rolled out simultaneously to Nexus and manufacturer skinned devices.

Check out the chart below for more information on the rollout of the Android 4.4.2 update. And as revealed before, the standard variant of the Galaxy S3 will not receive the update with the status being “unstable”.
