In this guide, you will be able to learn How To Install OxygenOS 3.5.6 on OnePlus 2 : The OnePlus 2 was released almost an year ago, and while it didn’t at all live up to its expectations, it was still considered to be a crowd favorite. Sporting the best specs in any phone at that time, the OnePlus 2 rocked a Snapdragon 810, 4 Gigabytes of RAM, Adreno 430, a great camera, and an amazing build. In spite of the crazy sepcs and the good build, it did manage to fall down way below under the price bracket of $400.
