Owners of several recent Samsung high-end devices who are itching to get their hands on the latest Android 4.3 version might now have their need satiated, that is if the devices were purchased from AT&T. Several builds for Samsung's Android 4.3 update have been leaked and are ready to serve the AT&T Galaxy S III, Galaxy S 4, Galaxy S4 Active and Galaxy Note II.
The firmware collection comes from Android developer DesignGears and only covers AT&T variants of the devices. Considering that it was just recently leaked that the official Android 4.3 update will be rolling out in a few days, the leaked images might be unnecessary. However, of the major US carriers, only AT&T's schedule is still unknown, so eager beavers might opt to not wait for weeks and try their luck with these unofficial updates.
One reason such users might be excited to update as soon as possible could be the fact that this update brings in support for the Samsung Galaxy Gear smartwatch. Last week, Samsung officially announced which smartphones, aside from the Galaxy Note 3, will be receiving support for the wearable device via an Android 4.3 update. However, of those included in that list, only the Galaxy S4 Mini, the Galaxy Mega 5.8 and the Galaxy Mega 6.3 still don't have any leaked Android 4.3 firmware, so owners of those devices will just have to wait for the real deal.
As these are pre-release builds, great care must be taken in installing and using the firmware, as bugs might still be present that have already been addressed in the final builds. Those who really can't wait, for one reason or another, are, of course, free to proceed at their own risk, hopefully with a proper backup and recovery image at hand.
