As for Samsung's flagship, the Galaxy S6 features a 16MP primary shooter with LED flash and f/1.9 aperture, which is the same as the LG G4 but even lower f/1.8 aperture for LG's flagship.

On the front side of the devices, the OnePlus 2 and the Samsung Galaxy S6 pack identical 5MP sensors, while the LG G4 is a step ahead with its 8MP shooter.

Processor

All three smartphones have different type of processors. Samsung takes the lead with its home-grown Exynos 7 series Quad 2.1GHz + Quad 1.5Ghz octa-core SoC, which has the highest benchmark score in the industry.

The OnePlus 2 is powered by an octa-core 64-bit Qualcomm Snapdragon 810 v2.1 SoC while the G4 smartphone gets treated with a 1.8GHz 64-bit hexa-core Qualcomm Snapdragon 808 chipset. Given the high-end processors, you can bank on any handset for an exceptional lag-free performance.

Software

All three smartphones are powered by Google's latest Android Lollipop operating system. The LG G4 customizes the OS with its new human-centric UX 4.0 to include features such as Quick Shot, Smart Notice, Event Pocket and more. The Samsung Galaxy S6 comes with its own TouchWiz UI. As for OnePlus 2 smartphone, it runs an entirely different OxygenOS based on Android 5.1 Lollipop.

Battery

The OnePlus 2 leads in the battery department. The combination of a 3,300mAh battery along with use of LPDDR4 RAM guarantees lasting smartphone usage. Comparatively, the Samsung Galaxy S6 packs a 2,500mAh non-removable battery and the LG G4 gets a 3,000mAh unit.

Although the current prices for both the flagships have dropped since the release, they still fail to match the competitive price of OnePlus 2.

The OnePlus 2 16GB variant costs ₹22,999 while the 64GB model sells for ₹24,999.

Availability

Both Samsung Galaxy S6 and LG G4 smartphones are available through various online and offline channels. But the same cannot be said about the OnePlus 2, which is sold only via invites.
