This represents an interesting change over last year's A series and their screen sizes, as well as resolutions. Here is how Samsung has changed the display sizes:
- Galaxy A7 (2016 vs 2015): 5.5" Super AMOLED displays with 1080 x 1920-pixel resolutions on both
- Galaxy A5 (2016 vs 2015): 5.2" vs 5.0" Super AMOLED displays with 1080 x 1920-pixel resolution on the 2016 model and 720 x 1280-pixel resolution on the 2015 model
- Galaxy A3 (2016 vs 2015): 4.7" vs 4.5" Super AMOLED displays with 720 x 1280-pixel resolution on the 2016 model and 540 x 960-pixel resolution on the 2015 model
This is quite a significant change for the more affordable Galaxy A5 and A3 models that brings them up to date, as keeping last year's resolutions would have definitely been a critical flaw in today's market.
The other major change is that now all three new phones come with 13-megapixel rear-facing cameras and 5-megapixel selfie cameras, both wide-aperture, f/1.9 lenses. We do suspect that there will be differences in the actual image quality, but it would be interesting to see whether that's in fact true and to what extent.
The other two key areas to look for are processors: the system chips inside the new, 2016 Galaxy A series have been updated, and battery sizes vary between models, so that the A7 has the larger battery (and possibly, the best battery life of the trio). For the rest of the specs and all the details, take a look at the chart below.
