If your smartphone is part of the list below, it should not take long to migrate to Android 4.4.4 KitKat. Perhaps it is already available.
While the arrival of Android 5.0 or Android L which is more imminent, a document relayed by JustAboutPhones website allows you to review the migration of smartphones from Samsung to Android 4.4.4 KitKat operating system.
If you own Galaxy Note 3 and Galaxy S5 smartphones, you should not be delayed to be served with this update or are perhaps already at the time these lines are written. The document indeed indicates that the new firmware has spent the last tests successfully and they must be organized from this month.
If you own a Galaxy Note 3 Neo, a Galaxy S4, an S4 Galaxy Mini, a Grand Galaxy 2 or a Galaxy Note 2, you will have to wait a little bit against by. The document refers indeed about firmware being tested more or less advanced for deployment scheduled during the month of November. It would be the story of a few weeks before the first notifications.
At this rate, many would probably accept a few weeks or months to just go to Android 5.0/Android L, which many of the smartphones mentioned will likely be eligible. Now it's nice to enjoy the improvements and bug fixes as soon as possible that tarnish the user experience.
