Samsung Galaxy A3, A5, A7 (2017) release date: When is the new Samsung Galaxy A series coming out?

A UK release date has not yet been confirmed by Samsung. The company has said the phones will go on sale in Russia in early January, and then will be expanded to global markets.

Samsung Galaxy A3, A5, A7 (2017) UK price and pre-order: How much is the Galaxy A3, Galaxy A5 and Galaxy A7?

Neither has Samsung confirmed official pricing for the Galaxy A series 2017, though our friends at MobileFun have confirmed that the Galaxy A3 will be available from £299 and the Galaxy A5 from £399. At a guess we'd estimate the Galaxy A7 to therefore cost around £499.

Both Galaxy A3 and A5 are available to pre-order now via the MobileFun website, though we suggest at these prices you also consider Samsung's outgoing flagship Galaxy S7 (now £452 at Amazon) and the Galaxy S6 before it (£369 at Amazon).

Samsung Galaxy A3, A5, A7 (2017) specifications: What's the difference between Galaxy A3, Galaxy A5 and Galaxy A7?

Samsung's upgrades to its Galaxy A series for 2017 include a bump in storage (from 16- to 32GB), microSD support (from 128- to 256GB), a new always-on display, IP68 waterproofing, a USB-C port and improved cameras.

All three models feature a fingerprint scanner and the now-familiar metal frame with glass front and rear. The Galaxy A series will be available in Black Sky, Gold Sand, Blue Mist and Peach Cloud.

As in previous years, the key differences between the three Galaxy A-series models are their screen sizes and resolutions, battery capacity and performance.

The Galaxy A3 is the smallest, least powerful of the trio, with a 4.7in HD screen, a 1.6GHz octa-core processor, 2GB of RAM, 16GB of storage and a 2,350mAh battery.

The Galaxy A7 is the largest, most powerful device, with a 5.7in full-HD screen, a 1.9GHz octa-core processor, 3GB of RAM, 32GB of storage and a 3,600mAh battery.

The Galaxy A5 sits in the middle, and is expected to have similar performance (and battery life, given the smaller battery but also smaller screen) to the A7. Full specifications are provided in the comparison table below.
