Wondering which of Samsung devices will be getting the update to Android 4.4 KitKat, and when? Well, thanks to an internal document that we obtained from a tipster and have confirmed to be legitimate, we have a list of the Samsung phones that are getting the much awaited update. As you can see in the image below, the devices confirmed to be getting KitKat include the Galaxy S III LTE, Galaxy S4 mini (and S4 mini LTE), Galaxy Grand 2, Galaxy Mega 5.8 and Galaxy Mega 6.3. We've already known that these devices will be getting updated, but today's leak also reveals that the update is expected to start rolling out to those devices sometime in June, though that is just an estimated time frame instead of a concrete one.
The document also reiterates something that we had hoped wouldn't be the case – the international Galaxy S III (GT-I9300) isn't getting KitKat, due to “unresolved problems”, which we're guessing has to do with the fact that it only has 1GB of RAM (the LTE and US models have 2GB.) However, our tipster has said that Samsung is under pressure when it comes to its third-generation Galaxy S flagship, as Google has apparently warned it that the device was less than 18 months old when Android 4.4 was released, though we're not sure Google has a say in these matters, so we'd suggest taking this with a grain of salt.
Our tipster also tells us that Samsung has started testing Android 4.4.3 for the Galaxy S5 thanks to images of the new build of Android sent in by Google, and that some of the devices in the list might upgrade directly to 4.4.3 instead of 4.4.2, which hints at the possibility that the updates might take longer to arrive. Devices like the Galaxy Note II and Galaxy Note 3 Neo are already on Android 4.4.2, but we'd expect these will also be hopping on to 4.4.3 somewhere down the line.
UPDATE: The tipster has now sent us a developer report of Galaxy S3's Android 4.4.2 KitKat test build. As you can see in the screenshot below, it looks like Samsung is having a bit of trouble implementing its TouchWiz applications, which is stopping the device from loading system apps. At least one thing is clear that RAM is not an issue with the Galaxy S III. For now, the Android 4.4.2 KitKat upgrade has been cancelled by Samsung's dev team until further notice.
