Samsung Galaxy S9 vs Sony Xperia XZ3.


The Samsung Galaxy S9 is an excellent smartphone, the stunning design and cameras of excellent quality. However, it should not be under-estimated, the Sony Xperia XZ3 which is newer and cheaper, maybe it will be to your taste.

We have used both the phones and have consolidated their differences, strengths and weaknesses.

Price of the Samsung Galaxy S9 and the Sony Xperia XZ3.

In France, the Sony Xperia XZ3 is sold from €799, a price that we can qualify decent for a flagship phone released in 2018. It is less costly than the Galaxy S9 which is to 859 €.

Design of the Samsung Galaxy S9 and the Sony Xperia XZ3.

The Galaxy S9 looks a lot like its predecessor, the S8, which is rather a good thing. Its design has even been mimicked by other models, and by the XZ3 to a certain extent.

The S9 has a screen, Infinity edge-to-edge that covers the front of the smartphone. This provides a sense of immersion rather than a flat screen.

The screen of the XZ3, Sony is curved and its edges are similar to those of the S9, but its back is curved.

Side connection, Samsung has made the choice to keep an output Jack on the S9, what we particularly appreciate. By contrast, the XZ3 does not have one, you’ll need to use a dongle USB Type‑C or a Bluetooth headset. In addition, the two phones are equipped with stereo speakers, a first for the brand in south korea.

To the rear of the XZ3, we find the fingerprint reader, but this one is oddly placed in the middle. Also, unlike the S9, the sensor of the XZ3 takes a rounded shape.

All in all, the S9 is slimmer (8.5 mm compared to 9.9 mm for the XZ3), and its edges top and bottom are a little thinner. The Samsung Galaxy S9 is also much more lightweight, it weighs 30 grams less than the XZ3.

The Galaxy S9 uses different processors depending on the country where it is sold. In the United States, for example, it works with Snapdragon 845, just like the Xperia XZ3, but in France, the S9 uses the Exynos processor 9810 (slightly faster).

The RAM is the same on the two models, 4 Gb. There is a version with 6 Gb, but it is only available in Taiwan.

Once again, depending on your country, the S9 is available with 64, 128 or 256 Gb of storage space. In France, it has a capacity of 64 Gb, the XZ3 is, him, available with 64 Gb. However, on both phones, it is possible to extend this space up to 512 Gb with a microSD card.

In regards to the screen, the Sony is 6 to 18 inches:9 so that the S9 measure 5.8 inches 18,5:9. They are virtually identical, but we find the S9 a little easier to hold in one hand.

For images, the objective variable opening of 12 Mp of the S9 adapts to the lighting conditions. The XZ3 is equipped with a device 19 Mp, but Samsung has devices, of a superior quality.

The S9 and the XZ3 have a water-resistance rating of IP68, which enables them to survive a dip coincidental.

One or the other offers very nice performance, and are lightning fast. To tell the truth, their technical characteristics are quite similar. Your choice will depend largely on your tastes.

Operating system of Samsung Galaxy S9 and the Sony Xperia XZ3 .

The XZ3 and the S9 work (since the bit to the Samsung) Android Walk 9, like the Google Pixel 3.

Added to this, the Galaxy is equipped with interface Samsung Experience and the assistant Bixby, which you don’t really see the usefulness.. anyway, it is possible to disable it.

With the S9, you can create Emoji and on the XZ3, you have the 3D application Creator, it allows you to scan your face in 3D. We do not have a preference, the two programs we like.


The Galaxy S9 is a safer buy because Samsung is a guarantee of quality. However, Sony remains a competitor not to be taken lightly, its XZ3 features a stunning design and it comes with Android Walk 9. In addition, the S9 has a better camera and it has a headphone jack. This is, without doubt, the only real differences between these two models.

In summary, it will rather be a question of know which design you prefer and if you want to take advantage of the interface Samsung.
