Owners of older Samsung devices are likely wondering when they might see another update, and a newly-leaked document now sheds some light on this matter.

Android 4.4 KitKat is not exactly brand new anymore, yet the latest version of Android has yet to see a wider adoption. Top-notch flagships and other devices debuting now generally come with KitKat out of the box, but what about older devices that have yet to receive an upgrade to the new Android flavor?

While the wait may seem to take ages for older Samsung devices, the folks over at SamMobile have obtained what looks like an internal Samsung document, detailing when various devices are scheduled to get the latest chocolaty treat. According to the leaked chart, the Galaxy Note 3, Galaxy Note 3 Neo, and Galaxy S3 LTE are set to get an upgrade to KitKat this month. All three of them have already received an update on Sprint's network, and it's about time they got the new Android flavor.

The chart further lists other Samsung devices such as the Galaxy S4 Mini, Galaxy S4 Mini LTE, Galaxy Grand 2, Galaxy Mega 5.8, and Galaxy Mega 6.3, all of which will apparently receive updates in June.

As always in such cases, the dates listed here are most likely subject to change, and it wouldn't be a big surprise if the update arrives sometime before or after the estimated dates. Meanwhile, plenty of other popular, yet older Samsung devices don't appear on this list. This doesn't necessarily mean they will never see an update, but it will likely take a while longer.

It's also worth pointing out that while the Samsung Galaxy S3 LTE is listed as getting an update this month, the non-LTE version is MIA from this upgrade schedule. The device has reportedly faced some issues and it will likely take some time before it will get an upgrade to the KitKat flavor of Android. After the buggy Android 4.3 update, Galaxy S3 users are likely among the most anxious ones to get a new update that will hopefully make things right again. For the time being, however, it seems that only the LTE version of the Galaxy S3 will get the new treat.

At the same time, keep in mind that this is a leaked document, not an official upgrade schedule provided by Samsung. While it offers some likely timeframes and brings hope to owners of older Samsung devices, nothing on this list is confirmed. If the dates turn out to be accurate, we should hear more about these updates soon enough.
