Although the Samsung Galaxy S3 hasn’t really be out all that long, the Android smartphone has quickly become a hugely popular handset with the Android faithful, and will no doubt drag in a large amount of cash for old Sammy. However although the Galaxy S3 isn’t all that old, the mobile space is already looking towards Sammy’s next big handset in their Galaxy line, the Samsung Galaxy S4.

We have already posted several articles concerning the Samsung Galaxy S4, which some say might release to the mobile space sometime early in 2013, but no one really knows just what specifications the SGS4 will sport, or even what the device will look like.

However, as usual in the mobile space, when a new device gets mentioned, more often that not designers get to work on coming up with concept designs on what they think that smartphone should look like.

Naturally as anything on the Samsung Galaxy S4 is big in the mobile space, we have a couple of concept designs for your consideration today, kicking off with a Samsung Galaxy S4 and Galaxy S4 mini concept via concept-phones.

These have been designed by Ben Ling, with the Galaxy S4 sporting a 5-inch full HD Super AMOLED Plus touch screen, along with Corning Gorilla Glass 2, with a 2500mAh battery, LTE connectivity, a 13 megapixel rear camera with LED flash, 1.9GHz quad core processor, and 9.1mm thick, so nothing too unpredictable.

However the Samsung Galaxy S4 mini is a new fresh idea, with the handset sporting a 4.55-inch Super AMOLED TFT HD display, a 13 megapixel rear camera with LED flash, an 8 megapixel front facing camera, and a 1.5GHz quad core processor and a 2100mAh battery. Whilst both devices include such things as 2GB RAM, NFC, Android Jelly Bean 4.2, and come in 16GB, 32GB and 64GB versions.

Then there is the Samsung Galaxy S4 with TouchWiz 6, a design created by Nikolai Prettner, which brings a revamped version of TouchWiz to the Samsung Galaxy S4. However this time the device runs Android Key Lime Pie 5.0 along with TouchWiz 6, with S Note, S Music, S Voice, and S Gestures.

This concept of the Galaxy S4 has the device sporting a 5.1-inch Super AMOLED Flexible 1080p display along with a 1.9GHz quad core processor, a 12 megapixel rear camera and 4.5 megapixel HD front camera, LTE, HSPA+, wireless charging, a 2650mAh battery and in 16GB, 32GB, and 64GB flavours and weighing in at 10 grams less that the iPhone 5 at 102 grams and 0.1mm slimmer than the iPhone 5.

Then we have the Samsung Galaxy King concept designed by Shahin Jazirian, which does offer quite a unique shape for a smartphone, a device with sharp corners and a slanted design, so we are not too sure just how well that would work in your pocket.

However the Samsung Galaxy King concept specs aren’t too bad, with the device sporting a 5-inch Super AMOLED 1080p display along with 2GB RAM, 13 megapixel main camera, Android 5.0 Double Burger (not sure why it’s called that), and an Exynos 5450 quad core Cortex-A15 processor running the show.

The SG King would also come with TouchWiz, active noise cancellation with a dedicated microphone, S Voice, MHL, and Swype input. But really for me anyway that sharp angular design just doesn’t cut the grade.

Anyway, there you have three new concepts of Samsung Galaxy Devices, would you like to see one of the above become a reality in the mobile space in the future?
