If you're rocking an international 3G version of the Galaxy S3 (GT-I9300) or the Galaxy S3 mini, we've got some bad news. Samsung has officially declared that both the international Exynos-based Galaxy S3 and its smaller cousin will not be making the jump to Android 4.4 KitKat.
In a statement given to SamMobile, Samsung stated that the memory requirements of either device prohibit them from running KitKat effectively:
In order to facilitate an effective upgrade on the Google platform, various hardware performances such as the memory (RAM, ROM, etc.), multi-tasking capabilities, and display must meet certain technical expectations. The Galaxy S3 and S3 mini 3G versions come equipped with 1GB RAM, which does not allow them to effectively support the platform upgrade.
As a result of the Galaxy S3 and S3 mini 3G versions' hardware limitation, they cannot effectively support the platform upgrade while continuing to provide the best consumer experience. Samsung has decided not to roll-out the KitKat upgrade to Galaxy S3 and S3 mini 3G versions, and the KitKat upgrade will be available to the Galaxy S3 LTE version as the device's 2GB RAM is enough to support the platform upgrade.
Samsung's statement that 1 GB RAM is insufficient to effectively run KitKat is curious considering that many other devices run the OS on 1GB or less of RAM; Samsung's own Galaxy Ace Style, launched earlier this year runs Android 4.4.2 on just 512MB. However it's worth mentioning that the GS3's RAM has to accommodate not only the barebones OS, but all of Samsung's flagship-level software features too.
As per Samsung's statement, this restriction shouldn't affect the Qualcomm Snapdragon-based U.S. Galaxy S3s, which also carry 2GB of RAM. Sprint's LTE variant of the Galaxy S III made the switch to KitKat earlier this month.
