Test: Samsung Galaxy S7 – Le Journal du Geek

Like last year, Samsung offers two versions of its flagship range with the Galaxy S7 and Galaxy S7 edge .

After testing the Galaxy S7 edge, we tackled the Galaxy S7 classic with its flat screen and especially to those who are always looking for a top smartphone range but in a volume more content. With a screen of 5.1 “, the Galaxy S7 offers the same size as an iPhone 6 / Apple 6s.

Apart from the aesthetics and grip, the Galaxy S7 offers an almost similar user experience to the Galaxy S7 edge test which can be found HERE. Also, for the detailed parts such as the photo, the afficahge, TouchWiz or other, I can not redirect you to test the Galaxy S7 edge HERE.

As for the Galaxy S7 edge, the MicroSD slot is indeed back for our pleasure. With an internal memory of 8GB to 32GB which are occupied by Android and TouchWiz, support for MicroSD cards is a real plus for the storage of its multimedia content. By cons, as a reminder, Samsung has opted not to support the Storage Adoptable Google technology.

As a reminder, Adoptable Storage allows merging the smartphone’s internal memory with a memory card. The advantage is that it allows you to have a single internal memory and this, transparently to the user since it is Android 6.0 which will manage at best. The downside is that if your memory card is not fast genre, it could possibly slow your smartphone. In addition, because it would be formatted in a certain way, it will be impossible to use normally in another device. It is for these two reasons besides that Samsung has chosen the party not to incorporate Google technology. Now Samsung offers the ability to install applications on the memory card, the only requirement was to install the first on the internal memory and transfer them afterwards on the memory card. As for the Samsung Galaxy S7 edge, I just wish to have a choice.

the new Samsung Galaxy S7 still offer USB Type-C but continue with the classic Micro-USB port. According to Samsung, this is simply because for now, the adoption of the USB Type-C has not yet passed a strategic course. it is not wrong in absolute terms but leaves to innovate, as there now go and impose the standard, especially with Samsung’s strike force. This is all the more surprising insofar as it is currently testing the new Galaxy Tab Pro tablet S and you might expect, no Micro-USB port but rather a USB Type-C.

packaging side, there is a box that folds now. inside, there are the eternal micro-USB cable, USB charger, headphones / hands-free kits Earbud with a flat cable in a box and the operating instructions for a first grip. Nothing original so well if not the headphones that are doing quite well and I found quite comfortable. For its price, count € 699.



The Design

We will keep it simple around the Samsung Galaxy S7 design is a Galaxy S7 edge smaller and with a screen dish. We have not known in France but the Galaxy Note 5 Galaxy S7 also incorporates the principles, ie obviously flat screen but also a curved back on the sides. So, with the slices in aluminum was a mix for grip. The rounded back gives a softer grip and aluminum slices prevents smartphone slide too. This is completely subjective and subtle enough but to have it presented to several different people, all have preferred taking the Galaxy S7 iPhone 6 / 6s or Galaxy S7 edge.

the design is in itself always nice, finesse with two glass sides and an aluminum contour. Now it is clear that the flat screen finally makes it Galaxy S7 fairly standard in design. If you have been seduced by the curved screen of the Galaxy S7 edge, see the Galaxy S7 will give the impression of having a smartphone everything from classic. Too same ! to use the Galaxy S6 edge + for a while, I got used to the fact that the curved portion was synonymous screen. so, with the Galaxy S7, I often look back at the back of the smartphone while I thought I had the screen. as the Galaxy S7 edge, Samsung has modified some aesthetic elements such as Home button that offers more chrome surround. the aluminum outline offers clean curves, in line with design. The whole gives a sober and elegant overall appearance. The back glass, also curved, is very nice and as you can imagine, outside the white version will require attention to fingerprints. The side of the device volume, I was amazed at how Samsung has managed to contain the size of the Galaxy S7 with a screen of 5.1 “. Just compare the Galaxy S7 iPhone 6 / 6s with its screen of 4.7 “to see that they have the same footprint.

in terms of physical description, found the top of the first speaker with screen, at his side, an integrated notification LED in plastic, videocall camera with a 5 Megapixel sensor and proximity sensors and light. Just below the speaker is the Samsung logo. at the bottom of the screen are the physical home button that integrates the sensor biometric and two touch buttons. As with the previous Galaxy, we find left the application button that provides access to multi-task. however, a long press will start the menu option. on the other side is the back button.

samsung-galaxy-s7-live-03

About the Home button, I remind you that it incorporates the same biometric sensor than previous Galaxy S6 and you just have to put your finger to unlock the smartphone. In daily use happens without any worry and you can save up to 5 fingerprints. On the back we find the NPC in the top center with, at his side, the LED flash and the heart rate monitor. The Samsung logo is at the center of the back. We can always blame the overcoming of the camera in the back, but Samsung has made a big effort for it to be as thin as possible. This does not particularly bother me, but some may not like the fact that the smartphone may not rest flat on a table.
On the left spine are the two volume buttons on the side of slice right, we find the power button and / or standby. The nano-SIM port with Micro-SD slot is located on the top edge. You will find the 3.5mm jack port, the Micro-USB port, a second microphone and multimedia speaker on the bottom edge. As you will notice, the USB 2.0 port is not covered and I remember you and the Galaxy S7 is IP68 certified.

the screen and sound

Samsung will not change a winning formula. the screens of the Galaxy S6 and Galaxy S6 edge + were references the last year and still are today. the new Galaxy S7 and offers a slab Super AMOLED 5.1 “with a resolution Quad HD is 1440 × 2560 with a so 577ppp density. it’s a little late than its big brother, the Galaxy S7 edge. Quite honestly, you will not see significant differences with the naked eye. by cons, if the Gear VR you very interested, I can only advise you to prefer the S7 the S7 edge. with a smaller screen and the definition, you will see less pixels on the S7 with the Gear VR.

a side and no big surprise, the Samsung Galaxy S7 screen is simply excellent. The display is impressive finesse. With OLED technology, you guessed it, blacks are very deep and the colors jump out at you. And we know for a few generations, Samsung is doing with honors in color. Colorimetry is perfectly mastered. The viewing angles are very good and I did not have any problem of visibility in bright sunlight. A new benchmark with the Galaxy S6 last year.

samsung-galaxy-s7-live-02

Because it’s a flat screen, you will not have the feeling to have an image that comes out of the screen as the Galaxy S6 edge / edge and + Galaxy S7 edge. Similarly, no Edge UX function. Now, honestly, as the aesthetics of the S7 edge may miss, so the Edge UX function, I had turned off anyway.

in terms of multimedia speaker, as you can see, there is on the bottom edge, like on the Galaxy S7 edge. I was pleasantly surprised by the sound quality output as the speaker speaker arrives filtering and really do not saturate. it is roughly the same as what we had with the Galaxy S6. whether series of videos or Youtube videos, the sound remained clear. Now, it remains speakers and it will never replace a good helmet, good headphones or an external speaker. The DAC is similar to other Galaxy S6 and S7 edge, allowing to have enough power to enjoy your multimedia files, especially with the HiRes FLAC and other audio files.

samsung-galaxy-s7-live-10

as for the Galaxy S6, Galaxy S7 supports HD Audio as proposed increasing its competitors. Samsung always offers the Ultra High Quality Audio (UHQ Upscaler , UHQ-BT Codec) and the presence of an equalizer for better sound processing. I am not a specialist either and I’m sure that most audiophiles of you will find a use more in keeping with what offers Samsung. on the side of the application is fairly standard in the absolute, except it is not installed by default, download the app Samsung Music if you do not use Google Play Music, installed by default. Note especially that Samsung still offers navigation through folders. as for the sound quality during phone conversations, I have no particular problem and I got to clear conversations and a good reception general.

In use, TouchWiz UI and Gear VR

Performance and Battery Life

and to complement, we also launched the same benchmarks and here are the results, quite similar in itself:

<- see gallery_shortcode (! ) in wp-includes /> media.php ->

the Samsung Galaxy S7 offers a battery of 3000mAh and obviously fast charging and the wireless charging Qi-compatible and PMA (PowerMat). As you can imagine, the wired charging will go much faster than wireless charging. With the supplied charger, going from 0% to 100% in less than 90 minutes by Wired, this is awesome! In wireless, it will take two hours and smaller as for older Galaxy S6, Samsung promises 4 hours of use with only 10 minutes of charging. I remind you that with the wireless charging base, when the smartphone will be charged at 100%, the load will stop automatically.

autonomy, all of course depends on your usage . As was the case with the Galaxy S7 edge, I held a day without problems and I’m sure you can easily take on the day and a half or more. I used the Galaxy S7 in the same way connected with Gear S2 but also the Parrot Zik 3 for music and all the multimedia side.

samsung-galaxy-s7-live-08

Regarding autonomy benchmarks, the Galaxy S7 necessarily in doing with honors but the big problem of these benchmarks is that they are not the reflect a real daily use. as we have seen with our tests the autonomy varies between weekdays and weekends. So, it was found that during the weekend, with more use WiFi and video, Galaxy S7 showed excellent battery life, much better than a week with usage around emails, web, social networks and more.

Here is the status of the battery of Galaxy S7 after different days such use, this allows you to see how, with different types of use, the Galaxy S7 was rather steady:

And here still use a similar but I had to use the S7 HotSpot WiFi mode for a little over an hour:




Photo and Video

I had a little doubt, in case, but overall, I had the same performance, photo and video. The autofocus is super fast, clean and detailed pictures.

The Samsung Galaxy S7 offers and a backlit sensor of 12 Megapixels (1 / 2.6″ and 1,4μm) with a dual-LED flash and autofocus news generation, all accompanied by a wide-angle lens 26mm with an aperture of F / 1.7 and an optical stabilizer that will serve you greatly for photos in low light of course but also for videos.

Basically, this technology doubles the number of photodiodes per pixel and thus uses every pixel of the sensor to the development. So, the focus is really super fast. Now, honestly, to the eye one, you do not particularly see any difference with the Galaxy S6 that were already super fast in terms of development.
