The Galaxy S III Mini has a 4 inch screen - compared to its big brother's 4.8 inch size - as well as scaled-down computing power inside.
It runs on Android's 4.1 Jelly Bean operating system and is powered by a dual-core processor - about half the kick of the quad-core chip in the full sized version.
There is no mention, either, of LTE connectivity that would allow it to run on the soon-to-be launched 4G network in the UK.
In comparison, the recently-launched iPhone 5 has a similarly-sized 4 inch screen but, with a screen resolution of 1136 x 640 pixels, is sharper than the Mini's 800 x 480 display.
And at 5 mp, the Mini's camera loses out to the 8 mp version present on both the S III and the new iPhone.
So it's probably safe to assume that the Mini will be priced significantly lower than its higher-end competitors.
Samsung confirmed it'll go on sale in Britain in November.
