Leaked Android 4.4 KitKat Firmware For AT&T Galaxy S4

We have just told you that the Samsung Galaxy Note 3 KitKat firmware is rolling out globally, but now it seems that the company is already focusing its efforts for bringing the latest Android version on its Galaxy S4 in the near future too. Even more, we can actually talk about a leaked Android 4.4 KitKat firmware for the AT&T Samsung Galaxy S4 (SGH-i337) version having the I337UCUFMLD build number and a size of no less than 1.51 GB. You can only imagine that it is able to offer all those Android 4.4 KitKat improvements that we are dreaming of, the latest TouchWiz, better RAM management, new status bar icons, a much faster UI and so on, but there is something else that you should also know about it:

We want to tell you from the start about the existence of several reports from those that have already installed this firmware regarding a potential issue with the video player and a certain video codec, which makes the smartphone crash and reboot several times. And who would want anything like that to happen with its device? We all know the answer to that.

Even more, as our source informs us, you should also take in consideration that this Leaked Android 4.4 KitKat firmware contains a new bootloader, which means that once you go to KitKat, there is no easy way of going back to the Jelly Bean OS version. And to be honest, that is all that we know for the moment, but we cannot guarantee that there is no other issue waiting to make its appearance and cause even more discomfort.

In case you still decide to try it, you can find the download links here. But, although we are also sure that you are anxious about receiving this KitKat update on your AT&T Galaxy S4 as soon as possible, what do you feel about waiting for the official update? From what we know at this point, this official KitKat ROM will reach on late February or March, so you should just have a little more patience.
