Among the many smartphones released in the Samsung Galaxy series by Samsung in 2015, the Samsung Galaxy S6 followed by the Samsung Galaxy A8 cannot be missed out.

The Galaxy S6 rolled out along with an almost similar looking Samsung Galaxy S6 Edge rolled out in March 2015 with the Galaxy A8 making its presence felt a couple of months later in July. Both devices are ideally good choices for those who are looking forward to own medium priced gadgets. With the two handsets earning good ratings, it becomes necessary to do a comparative study on them to choose your right smartphone. Like most present day smartphones, you cannot remove the battery in them.

Dimensions, Weight, Control Buttons and Body Material

The size difference is just as obvious as the weight. With the A8 being taller and wider than the S6, if you expect it to be thicker as well, then you are in for a surprise. The S6 is at the forefront when it comes to the thickness quotient. The Samsung Galaxy S6 sizes at 143.4 x 70.5 x 6.8; whilst the Samsung Galaxy A8 has a measurement of 158 x 76.8 x 5.9. The Galaxy S6 weighing 138g is also not as bulky as the 151g Galaxy A8 smartphone.

The two smartphones have a volume control button on the left and a phone lock/unlock button on their left and right sides respectively. Regarding the material used for designing the devices, the S6 primarily has a glass body with aluminum accents. On the other hand, both the body and the accents of the A8 are made of metal.

Verdict: The all metal body and accents give the Samsung Galaxy A8 without doubt a posh and classy look. But if you want a smartphone that feels effortless when you hold it in your hand, we feel that you had better go in for the Samsung Galaxy S6.

Screen Display and Pixel Resolution & Density

Samsung is well known for adopting the Super AMOLED display technology as its mantra in most of the manufacturer’s devices. It is no different with the Galaxy S6 and the Galaxy A8. However, while the former features a Quad HD display; the latter comes equipped with a Full HD display. But owing to the overall smaller size, the 5.1-inch screen size of the S6 is smaller than the screen of the A8 that has a 5.7-inch screen. Despite the screen size shortcoming, the Samsung Galaxy S6 has an excellent pixel resolution and a pixel density of 1440 x 2560 and 577ppi. In contrast, the Samsung Galaxy A8 has normal 1080 x 1920 pixel resolution and 386ppi pixel density. Additionally, Samsung has ensured the screen protection of its Galaxy S6 with a Corning Gorilla 4 glass.

Verdict: There is no confusion here as to which Samsung device has a better screen. Although the screen is a tad smaller, the higher pixel resolution and pixel density result in the S6 displaying sharper images and text with enhanced clarity. Also, the display screen is not susceptible to scratches as much as the A8. However, if you are going to do a lot of browsings, extensive reading or movie watching; then you may find the Samsung Galaxy A8 favorable.


Both snappers are almost identical in the two Samsung Galaxy smartphones. Each device has a 16MP rear snapper with a single LED flash. However, the Galaxy S6 camera has a couple of features more than the Galaxy A8 camera that includes manual focus and optical image stabilization. While the S6 camcorder records 1080p HD and 720p HD videos, the A8 camcorder records 1080p HD videos. Even as the two camcorders can be used for video calling, the Samsung Galaxy S6 camcorder supports HDR, optical image stabilization, and simultaneous video recording and photo taking. As far as the front snappers are concerned, there is a 5MP snapper in each smartphone. Pressing the home button twice on either gadget launches the camera app directly.

Verdict: The optical image stabilization feature in the Galaxy S6 makes its rear snapper a better option if you intend capturing low light shots. Similarly, the ability to shoot both videos and photos at the same time can make using the S6 camera more memorable. These two features are not supported by the A8 snapper.

Configuration Setup

The two Samsung Galaxy smartphones come set up with Exynos octa-core processors of different clocking frequencies. The Galaxy S6 processor clocks at 1.5GHz as against the 1.8GHz processor in the Galaxy A8. It is also to be noted that the S6 houses 3GB RAM whereas the A8 has only 2GB RAM. As for the storage criterion, the Samsung Galaxy S6 has 32GB ROM without any way to expand externally with a memory card. Other variants of this device are available with 64GB and 128GB ROM. But, going for the high-end options increases the gadget price also greatly. The Samsung Galaxy A8 comes with only 32GB of internal storage. The manufacturer provides for externally expanding this up to a 128GB limit.

Samsung has chosen to integrate Android’s latest Lollipop with the TouchWiz UI for user customization in the two Galaxy gadgets.

Verdict: The higher clocking frequency of the A8 processor does not render a very fast performance compared to the S6 processor. But the fact that you can enhance the memory with memory cards makes it more feasible and economical to consider it over its counterpart.
