If you own the global 3G version of the Samsung Galaxy S3 , the bad news is that KitKat, the latest Android 4.4 update will not be coming your way.
According to a statement posted on the SamMobile blogsite, the company says the S3 and S3 Mini only have 1GB of RAM, which “does not allow them to effectively support the platform upgrade”.
However, Samsung has said the KitKat update will be made available for the Galaxy S3 LTE, which sports 2GB of RAM.
Interestingly, KitKat does run on phones with only 512MB of RAM, and KitKat is present on newer phones such as the Galaxy Ace Style which has 512MB RAM.
