OnePlus 3 the latest flagship device by Chinese manufacturer OnePlus is the holy grail of smartphones in the hardware department. OnePlus has been popular for providing over specced devices at a lower price point as compared to other flagships in the market. OnePlus 3 continues the tradition and has top of the line specs at just under $400.

OnePlus 3 boasts a 5.5 inch SAMOLED 1080p screen with a full metal body. It is powered by the Snapdragon 820 with whopping 6 gigs of RAM. The rear camera has been upgraded to 16MP with EIS and OIS for clear and noise free images. The battery capacity may have been reduced to 3000mAH but the Dash charge technology more than makes for it. Dash charge technology can juice up your Oneplus 3 to 60% in just 30 minutes. On the software front, OnePlus 3 runs the latest iteration of Oxygen OS. Oxygen OS has been improved a lot since the Oneplus 2 days but if you want a simple UI with the amazing performance you have to try H2OS for once.

The ROM also includes a command center-like menu for the toggles and other shortcuts. The performance of H2OS feels snappier than stock Oxygen OS. The ROM also supports dash charging out of the box.
