Samsung Launches the 2016 A Series: A3, A5, A7

Samsung Galaxy A7 (2016)

The Samsung Galaxy A7 (2016) is the biggest of the bunch, since there's no A8
yet. It boasts a 5.5" Super AMOLED screen with 1080p resolution and an octa-
core processor running Android 5.1 Lollipop.

The bezels around the screen of the new A-series have been shaved off,
making the phones impressively narrow. Their bodies are constructed of metal
and glass, just like the flagship Galaxy S and Note series. The Galaxy A7
measures 7.3mm thick (thicker than both the old A7 and A8) and weighs 172g
(that's heavier too).

  

On the plus side, the battery is now bigger at 3,300mAh battery and it
supports Fast Charging. You get an extra gig of RAM, 3GB total, though the
storage stays at 16GB. Good thing Samsung kept the microSD slot.

Also, the 13MP camera has a wider aperture, f/1.9, and features OIS. The
selfie camera also has an f/1.9 aperture, that sounds like the Galaxy S6
setup.

The Samsung Galaxy A7 (2016) has a fingerprint reader and Magnetic Secure
Transmission (the tech to emulate magnetic strip cards). The new chipset
brings LTE to Cat. 6 speeds (300Mbps, double what the old A7 got), a dual-
SIM option will be available.

Samsung Galaxy A5 (2016)

This one has outgrown its predecessor, it comes with 5.2" Super AMOLED
display with 1080p resolution (old A5 screen had a 5" 720p screen). The old
quad-core processor has been left behind in favor of an octa-core one
(Samsung is stingy with exact chipset model). RAM and storage remain at
2GB and 16GB respectively.

The Samsung Galaxy A5 (2016) is thicker too, 7.3mm up from 6.7mm, and
heavier, 155g up from 123g. The battery has grown too, 2,900mAh.

It uses the same camera as the A7, 13MP with OIS on the back and 5MP on
the front. A fingerprint reader and Samsung Pay with MST are on board too.
The Samsung Galaxy A5 (2016) will come in dual-SIM flavor as well.

Samsung Galaxy A3 (2016)

The Samsung Galaxy A3 (2016) got the biggest upgrade of the three. The
wimpy qHD screen has been replaced with a bigger 4.7" Super AMOLED unit
with 720p resolution.

Also, the camera bump to 13MP is significant, both it and the 5MP selfie cam
have f/1.9 apertures (no OIS here, though).

The processor remains at four cores and the RAM at 1.5GB, same for the
storage – 16GB. The battery goes up to 2,300mAh, once again at the cost of
thickness (7.3mm) and weight (132g). Dual-SIM will be available as an
option, LTE is set at Cat. 4 (this is market dependent though).

The Galaxy A3 (2016) is the only member of the new lineup to lack a
fingerprint sensor.
