Verdict:

In terms of design, the Galaxy S8 is clearly the winner here. It brings a refreshing design change with bezel-less display, offering more viewing real estate. For a large 5.7-inch display compared to iPhone 7's 4.7-inch display, Samsung does a great job at packing in larger display in a compact form factor at mere 155 grams.

 

The S8 has a higher display resolution, but there has never been much to complain about the iPhone 7 display either. On camera front, the S8 gets a dual camera setup, which is limited to only the larger and more expensive iPhone 7 Plus model. Samsung is powered by the most recent Snapdragon 835 and Samsung's own equivalent Exynos that is based on 10nm process.

 

Samsung is among the few devices running Nougat, and we assume it will get the Android O update, whenever it is released. Apple device runs on iOS 10. Samsung has also introduced Bixby to compete with Siri. However, Samsung has added other goodies like Dex, Connect and VR Oculus.

 

Samsung also takes a step ahead with biometrics with support for fingerprint, iris and facial recognition. This will further work in tandem with Samsung pay, the mobile wallet that was recently launched in India. Apple misses out of these aspects. Moreover, Samsung has bundled a high-end earphone, putting Apple to shame that expects people to buy its new AirPods for a whopping ₹15000.

 

 

Finally, Samsung has doubled the battery capacity, but Apple won't disappoint either with the capabilities of its battery supported by iOS.

 

On paper, Samsung definitely has an edge over the iPhone 7. However, let's not forget the iPhone 7 is Apple's 2016 model and is likely to launch the alleged iPhone 7s, iPhone 7s Plus and iPhone 8 later this year.
