Designed for the "young social explorer", the smartphone has a 4.5-inch Super AMOLED Plus screen, with a resolution of 480x800 pixels.
Powered by a 1.2 GHz dual-core processor with 1GB of RAM, the device runs Android 4.1 Jelly Bean and has a Li-ion 2,000mAh battery.
Users get just 8GB of internal memory, although that can be increased to up to 32GB via a microSD card.
As the phone is NFC-enabled, users can access AllShare Play for remote sharing of content on other Samsung devices, as well as S Beam for transferring movies, photos or music to another S Beam device.
There is a 5MP rear-fitted camera on the Galaxy Express capable of shooting HD 1080p video, along with a 1.3MP front-facing camera.
The Galaxy Express will be available to purchase in the UK in the first half of 2013. Pricing has not yet been announced.
