Samsung
It’s now been six months since Android 4.4 was released, but there’s still a host of Samsung phones which are still yet to join in the Chocolatey Multi-fingered goodness. Sammobiles has obtained a leaked document which outlines which phones will receive the update, as well as when the update is due.

The list, includes variants for the Samsung models shows a time frame for Android 4.4 updates which begins last month with the Note II and continues all the way to June with the Galaxy Grand 2 (which was never released in Australia) and the Galaxy Mega 5.8 and 6.3.

There’s some bad news though, people who purchased the original Samsung Galaxy S3 which included only 1GB of RAM will see that the GT-i9300 has been pulled from the schedule of devices getting KitKat due to ‘unsolved problems’. The LTE variant which came with 2GB of RAM is apparently fine though, and will see its update released this month.

These dates are really only a rough guide due to the fact most updates will need to be tested by carriers, but at least you have some idea of when Samsung is aiming for.
