Samsung Galaxy A71, A70 and A70s: What has changed?

Samsung Galaxy A71, A70 and A70s

The Galaxy S71 was formalized this morning, only 3 months after the arrival of the Galaxy A70s. Let’s take this opportunity to discuss the differences between these models.

The Samsung Galaxy A70 was formalized in April 2019, the Galaxy A70s in September 2019 and the Galaxy A71 in December 2019. Three very close dates for a very popular smartphone, the Galaxy A70 remained for a long time among the most wanted smartphones between May and September 2019.

This Galaxy A71 therefore belongs to the new generation of Galaxy AX1, with a Galaxy A51 also announced at the same time. We are interested in the changes between these generations.



It is not easy to mark clear differences between several generations of smartphones when the ads are linked every 4 months.

For the A71, Samsung has chosen photography. So we take advantage of four cameras instead of two, that’s a lot, with a new mode that was not available before: macro mode which allows close-up shooting. We take this opportunity to evoke macro photography which is not simply a close-up shot, we speak of macro photography when the size of the image formed on the sensor is at least as large as that of the subject photographed. In short, let’s go back to our A71.

Samsung also took advantage of the A71 to change the main sensor of its smartphone: it goes from 32 to 64 megapixels with an opening f / 1.8 (which was already the case on the Galaxy A70S). The ultra-wide-angle camera also goes from 8 to 12 megapixels, and the third 5 megapixel camera does not evolve. This latter camera still serves as a depth of field camera for portrait mode. Finally, as we have already said, the fourth camera is new and specialized in macro photography, with an optical that opens at f / 2.4.



The other big difference is the arrival of the Snapdragon 730 in place of the Snapdragon 675. The Snapdragon 730 uses an 8nm engraving (compared to 11nm on the S675), with a processor based on Kryo 470 hearts which should allow gain 20 to 25% more performance. We should also expect better graphics performance thanks to the Qualcomm Adreno 618 (instead of the Adreno 612).

The rest is aesthetic:  the Galaxy A71 has a hole in place of the notch on the top of the screen. It is also a little lighter, 179 grams against 183 grams.
