Samsung Galaxy S4 Mini to run on 1.6GHz dual-core Exynos 5210 processor

We've known for some time that Samsung has been working on variants of the Galaxy S4. Thanks to OLED-Display, we now have some more details about one of the variants – the Galaxy S4 Mini. While we already knew that the S4 Mini would be running on a 1.6GHz dual-core processor, we now know that it will be an Exynos 5210 chip.

There will be two variants of the S4 Mini – a regular one with 1GB of RAM and an LTE-enabled one with 2GB of RAM. The LTE-enabled version presumably has more RAM because it will be forced to use a weaker processor because of the need for an LTE chip. It will run on Android 4.0 out of the box and all of this will be kept alive by a 2100 mAh battery. Those interested in photography will probably like the S4 Mini's 8 megapixel camera, which would be the same shooter as the one on last year's Galaxy S3.

Will probably end up being a bigger version of the S3 Mini with more contemporary hardware

Earlier today, we saw a photograph taken with another one of the S4's variants – the camera-centric Galaxy S4 Zoom. The photo, titled Morning View, was taken by Shahriar Hossain, who incidentally works with Samsung. It seems to have been edited using the SnapSeed photo editor.

Of what is known at the moment, the S4 Zoom will have a 4.3-inch Super AMOLED screen with a qHD resolution, which is considerably smaller than the 5-inch full HD screen on the S4. The S4 Zoom is said to have 8GB of internal storage and a microSD slot that can be used to expand memory up to 64GB. Connectivity options include Bluetooth 4.0 LE, Wi-Fi and A-GPS. It will come with Android Jelly bean with Samsung's own TouchWiz Nature UX.

Another S4 variant, the Galaxy S4 Active recently obtained its Bluetooth certification and had shown up on the website for the Bluetooth Special Interest Group.

The S4 Active is said to be a ruggedised version of the S4. It will have a shock-resistant design and will bear the IP certifications to make it waterproof and dustproof. The handset's codename is GT-I9295 and, as per an earlier report, it will be available in Metallic Orange.

All of this – the waterproof and dustproof design – put the Galaxy S4 Active in direct competition with Sony's flagship Xperia Z as well as the recently-announced Xperia ZR. If Samsung manages to avoid Sony's missteps, the company could have a winner in its hands.
