There has been alot of talk recently about whether or not the S3 i9300 will get kitkat
This was leaked


Samsung stated this
“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 Mobile UK
I really don't understand this, the 4.3 update works fine on 1gb of ram so why cant Kitkat, Especially when it uses less ram, Google stated kitkat was designed to perform better on devices with 512mb ram
