According to Samsung, the Galaxy S III and the Galaxy S III mini are
not capable of running KitKat smoothly as both have only 1GB of RAM,
which has apparently not been enough to get KitKat working properly on
either device. Here’s the official statement that
sammobile received from Samsung:
“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.”
