On paper, as already indicated, nothing changes: a 12 megapixel sensor with dual Pixel, autofocus, optical stabilization with 26 mm and f/1.7 aperture. Both also have a single LED flash. And, in fact, the behavior on both phones is similar, but not identical. There has been a good improvement in software management with encouraging results. The Galaxy S8 Plus manages to create sharper and more contrasting images, and improves from the point of view of white balance and cleanliness. At night the step forward is particularly evident, while during the day you have to see the photos on a PC to appreciate the difference.

As for the front camera, there is a considerable change here. Now it's a slightly less wide, but more defined sensor, which in fact goes from 5 to 8 megapixels. Equipped with autofocus and recognition, these features are often a success for selfies. In this case, the superior quality is much more tangible, while at night the improvement is less evident. As for the video, it has been subject to minor adjustments, a bit in contrast management and stabilization able to better mitigate the rolling shutter effect.

A certainly important aspect that relates to battery life and affect the final decision of all those who intend to renew their phones (especially on top of the varied offer).

In this regard, the Samsung Galaxy S8 Plus is proving to be able to withstand comparison with its predecessor, improving a bit with better and lower battery (100 mAh are not many, but still represent a decrease compared to the past, at least at a purely technical level). Fortunately, the optimization supposedly made by the chipset has favored the Samsung Galaxy S8 Plus.


The price of the Smasung Galaxy S8 Plus is now around $ 1,000, while the price range of the S7 Edge varies between $ 490 - $ 917. In any case, it is expected that in the coming months prices will fall and the Samsung Galaxy S8 Plus will be more accessible for many more people.

The Infinity Display, the improvement of the photographic section, the optimization of the CPU and a really unique design win the title of winner in this comparison. However, the Galaxy S7 Edge, to date, is still a very good device, especially at the current price, but if you want the best of the best, it is obvious that you should go directly for the Galaxy S8 Plus.
