I have a Samsung S3 smartphone purchased in Hong Kong. The phone currently has Android version 4.0.4. I am unable to upgrade vis Kies which tells me that the device canno0t be upgraded via that means. using the Settings menu update tab also draws a no software available response.

Is there an upgrade to a higher version of Android, & if so how do I access & install same ?
