Samsung Galaxy S7 edge review

After many years of the not so good plastic-clad design, finally we saw a new Samsung design on the Galaxy S6 and S6 Edge. Replacing the plastic covering, the new S6 series gave us a metallic frame placed between a glass front and back.


The Galaxy S6 Edge is a wonderful device; the design is near perfect with the curved edges. It successfully wins the market and has tons of praise throw to them. Even with the lack of removable battery and microSD slot the galaxy S6 Edge is still a high end device that stands out from the competitors. Now with the release of the Galaxy S7 edge, does it make enough changes to impress us like its predecessor? We will see at the review of the Samsung Galaxy S7 Edge.


The most noticeable difference you will see is the phone’s size. The Samsung Galaxy S7 Edge has a 5.5-inch display, making it appears larger than the original Galaxy S7. This big display gives you more fantastic experience for all the gaming and multimedia needs. The camera bump is reduced when compared to its predecessor, make it less bothersome.

Next, the S7 Edge is somewhat thicker than both the S6 Edge. Sound like a bad thing, but actually it helps with grip, as the S7 is larger. One improvement is the curved glass helps reduce the ‘sharpness’ issues like what Galaxy S6 Edge user said.

The other element has no special changes. On the front side, you will find the typical home button, on the left there is a recent apps key, and to the right the back button. All the sensors and front camera are on its usual place. You will also find the volume keys on the left side of the phone are and the power button on the right side. On the top, there’s a SIM/SD Card slot. On the bottom, you will find the

headphone jack, the microUSB slot, and the single speaker. The microUSB slot is probably the most surprising aspect here.

Overall, the Galaxy S7 Edge is not totally different from its predecessor, but with some improvements and minor difference, the Galaxy S7 looks like the most attractive handsets in the mobile phone world.


It’s hard to beat Samsung when it comes to display quality. While the S7 Edge’s Super AMOLED display is very similar to its predecessor the S6 Edge, Samsung expanded the size of its new device, from 5.1inches to 5.5inches. While this makes a pixel density lower (534 ppi vs 577ppi), you will not see any major differences, the larger size means watching movies, gaming, and anything else you want to do is better.

Every positive aspects of AMOLED screen are here in the S7 Edge. Vibrant and saturated colors, awesome viewing angles, precise blacks color, and brightness that is good enough even when on the outdoor environment.  The AMOLED displays are also efficient on energy consumption; it doesn’t take so much from your already good battery.

Performance & Hardware

The S7 Edge is released with the Exynos 8 processor. It packs with 2.6 GHz Mongoose quad core plus quad-core 1.6GHz Cortex-A53. Powered with a Mali-T880 MP12 GPU and 4GB of RAM. In some area (the United States and China), the Galaxy S7 equipped with a Qualcomm Snapdragon 820 processor that consists of a dual core 2.15 GHz and dual core 1.6 GHz plus Adreno 530 GPU.

So is there any difference in performance of these two processors? Exynos and Snapdragon. We ran a couple of benchmark tests, the AnTuTu, GeekBench 3, and 3Dmark.

On the GeekBench 3 test, the Exynos device scored a 2107 on a single core test and a 6397 multi core test, the Snapdragon 820 scored a single core score of 2210 and multi core score of 5230. The Exynos 8 is surely scored better at multi core test because the chip is an octa core and the Snapdragon is a quad core. For the single core test, the Snapdragon 820 is a little better, but the difference isn’t too much.

On the AnTuTu test, it also shows that there is no great difference in performance, the Exynos scored 127,507 points and Snapdragon 820 scored 127,938.

3Dmark tests the graphic performance, while the processor’s performance is not showing such a big difference there is a noticeable difference when we talk about the GPU. The Mali T880 GPU scored 2157, the Adreno 530 GPU on the other hand successfully outperformed it with a score of 2528.

Eventhough the Snapdragon 820 device statically performs better than the Exynos 8890 in terms of their GPU; you will not notice it in your everyday use. Both phones is still working nicely, they handle everything from general usage of multi-tasking and even gaming smoothly. The overheating problem is not a problem anymore in these two devices.

On the hardware aspect, Samsung also has a few noticeable elements of hardware:

MicroSD card slot

One of the most controversial changes on the Galaxy S6 and S6 Edge was the absence of microSD slot and replaceable batteries. While the removable battery is still absent in the Galaxy S7 Edge, themicroSD slot has returned! It allows you to expand up to 200GB of memory.

The water resistance

The Galaxy S7 Edge now has an IP68 rating waterproof; it means that the S7 Edge can be submerged for up to 30 minutes on the three feet depth of water. It is very useful for, just in case, the worst happens to your phone, it will still able to handle it.

Fingerprint scanner

The scanner mostly remains the same as the previous Samsung device, but the fingerprint sensor on the S7 Edge feels a lot faster and more accurate. It is very rare to have this scanner not reading the finger print in the first attempt.

Speakers and connectivity

If you are often using the built-in speaker, you must be prepared because it’s far from what we used to experience. The speakers are far from the front-facing speakers like the one that HTC or Motorola has.

The Galaxy S7 Edge features Category 9 LTE, it supports up to 450Mbps connectivity speed. The Category 9 connectivity also offered in the Note 5 and Edge Plus. The Galaxy S6 Edge also already featured Category 6. Some of the newer device might also featured Cat 9 in the near future.

Battery life

Samsung finally put the proper battery size and life with the Galaxy S7 Edge. Specifically, the 3600 mAh battery equipped in the Galaxy S7 Edge makes you can get through the day with enough battery, and with a lighter use you can make it through more than a day without charging. Plus, the removable battery makes almost everybody happy.

If you have the Snapdragon 820 version you will find Quick Charge 2.0. While you don’t have the newest version the 3.0, the charging speed is not much different. The Exynos model gets Samsung’s Adaptive Fast Charging standard. Both of the models also support Samsung’s fast wireless charging.


Samsung decided to put something different with the Galaxy S7 Edge. It has a 12MP camera instead of the 16MP like its predecessor.

While the pixels may be lower, the low-light performance has increased, similar to what we saw from Nexus. The Galaxy S7 has an f/1.7 aperture lens on it camera, LED flash, optical image stabilization, and phase detection autofocus. The result is the S7 camera has a faster autofocus, especially in low light compared with another smartphones.

As for the picture quality, it still pretty good overall. Pictures are very detailed and look good in both bright indoor and outdoor environment. For video recording, you have a plenty of modes here. The ability to record 4K videos and OIS feature to reduce the shaky when recording the video. 5MP front camera performs just how you would expect. Low-light images look less smooth, but in good lighting, you can have some good shots. A special thing about the front camera is that you can record video at QHD resolution.


The Galaxy S7 Edge, the combination on software is still the same. Despite being built on Android Marshmallow, it looks very similar to the previous version. But there are also some changes, such as the notification lights, and animation effects.

I personally have no big complaints about the UI performance. I even found TouchWiz to be a nice UI overall. Even though it’s a subjective thing, but if you’ve have no problem with TouchWiz previously; you will not have something to complaint. 

Pricing and final thoughts

Samsung has done quite a great job with the S7; they refine and evolve the galaxy S6, the winning formula. Mission accomplished. With a few changes and improvement, Samsung successfully fix each and every negative aspect S6 has and deliver a wonderful S7.

If you miss the microSD slot, Samsung brought it back in Galaxy S7; you even have the waterproof feature, something you already see on the Galaxy S5. Samsung brings every good aspect they have ever made onto one device.

One thing to complaint is the lack of a removable battery. But Samsung also puts a little remedy on it by combining a great battery life and fast charging feature.

So overall, the Galaxy S7 Edge is not a ‘perfect’ phone, but it’s pretty damn close. If you have no problem with the TouchWiz and want a well-performing phone with astounding appearance and a complete feature, Samsung Galaxy S7 Edge should be on our list. Please remember that Galaxy S7 isn’t the cheapest phone out there, with the $800 price tag mark, even though it’s totally worth it, price should be in your consideration.
