Samsung's A series of devices have always been solid offerings. To keep the trend going, the South Korean manufacturer has refreshed its trio of A series smartphones for the new year. The three devices hit different size and specification points, starting with the 4.7" A3, then the 5.2" A5 and larger 5.7" A7. 

All three devices feature a similar design, with a metal frame and glass back cover, akin to the Galaxy S6 when it was first debuted. Added to this will be a choice of four different colours per phone - Black Sky, Gold Sand, Blue Mist and Peach Cloud. At this stage, it's unclear which colour options will be made available in South Africa. Also amiss is the local release of the 2017 A series, with only Russia being detailed by Samsung to be the first to receive them later this month. 

As far as specifications go, all three devices are Cat 6 LTE compatible, with the A7 and A5 sporting Full HD Super Amoled displays and A3 featuring an HD variant. The A7 and A5 also share a similar 1.9 GHz octa-core chipset, with the A3 a slightly slower 1.6 GHz version. The two larger devices have the same 3 GB RAM and 32 GB onboard storage options, as well as a 16 MP camera on the rear. The lesser specced A3 drops the RAM  and megapixels to 2 GB and 13 MP respectively. 

All three will be setup for Samsung Pay, but the recommended price of each device is yet to be disclosed.
