Samsung Galaxy S7 vs Galaxy S8: how do they compare?

Samsung Galaxy phones

The Samsung Galaxy S8 has been heralded as one of the best new smartphones on the market, but how does it compare to the innovative Galaxy S7? We take a closer look at what sets the S8 apart from its predecessor – including its new additions, enhanced features, and jaw-dropping design.


The S8’s striking edge-to-edge screen is bound to catch your eye – at 5.8-inches, it’s distinctly larger than the S7’s 5.1-inch screen. Samsung retained the metal and glass design and premium finish, but with curved edges and ultra-slim bezels. The physical home button has been removed, and the fingerprint sensor now sits on the back of the phone, next to the camera.

Despite its increased screen size, the S8 is only slightly taller than the S7, thanks to an 18.5:9 Infinity Display and impressively high 83.6% screen-to-body ratio.


The Galaxy S7 is known to have one the best displays on any smartphone, but Samsung managed to make the S8’s display even more remarkable. Boasting Super AMOLED technology, the S8’s screen resolution is 1,440 x 2,960 QHD+ resolution – replacing the S7’s 1,440 x 2,560 QHD display. This provides a sharper, brighter, and more vibrant image.

With HDR Premium, the S8 also supports mobile playback of HDR content, which is available from services such as Netflix and Amazon Video.


Speed and efficiency are ultimately two of the S8’s standout features. This phone is powered by the Qualcomm Snapdragon 835 chip or Samsung’s Exynos 8895 processor – depending on your location. This produces a noticeable difference in the S8’s processing speeds: apps launch faster, battery life is improved, and power consumption is reduced by 20%. Both devices are loaded with 4GB RAM, but the S8 boasts 10% greater CPU performance compared to the Galaxy S7.

S7 vs S8


Apart from the newly added ‘multi-frame image processing’ feature, the S7’s impressive 12MP rear camera is identical to the S8. However, this new feature drastically improves image quality: it quickly captures three photos, combining them to create a sharper, highly-detailed image.

The front-facing camera has been upgraded to 8-megapixels with autofocus and facial recognition technology, while the S7 has a 5-megapixel camera with fixed focus. This means your selfies will turn out clearer and more refined than ever before.

Fun photo editing options have also been added to the S8, with a range of new filters and stickers available – similar to those on Snapchat and Instagram Stories.


Bixby is one of the biggest additions to the S8; this virtual personal assistant can help you complete a number of tasks – everything from checking the weather to sending a photo from your phone’s gallery – with a simple voice command. Initially, it will only work with a small number of pre-installed apps, with others set to be added in the future.

The Verdict

Should you overlook the Galaxy S7? Absolutely not. It’s still touted as one of the most incredibly innovative and powerful smartphones on the market. However, Samsung has managed to take the most impressive aspects of the S7 and enhance them to create a truly ground-breaking phone with the Galaxy S8.
