Moving on to actual specs, the less-featured of the three, the Galaxy A3 (2017) sports a 4.7-inch Super AMOLED display with HD (720p resolution, along with fingerprint sensor and USB Type-C port.

The Galaxy A5 (2017) has 1.9GHz octa-core processor at its heart, coupled with 3GB of RAM and 32GB storage (expandable up to 256GB). It's also powered by a larger 3,000 mAh battery, and, just like the Galaxy A3 (2017) features fingerprint sensor and USB Type-C port.
The Galaxy A5 (2017) and Galaxy A7 (2017) benefit from fast charging technology, and all three features IP68 certification for dust and water resistance. They come with premium metal frame and 3D glass back.
Sadly, the Galaxy A (2017) series phones ship with Android 6.0.1 Marshmallow operating system onboard. Hopefully, Samsung will deliver Android Nougat updates to all three handsets in the future.
