Install OxygenOS 3.5.6 on OnePlus 2

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.

Very recently, the OnePlus 2 got an update to OxygenOS 3.5.5, which introduced a new UI with a ton of new features. However, many users (including me) have been facing annoying network drop issues while using both the SIMs. Being a dual SIM device, the OnePlus 2 is facing issues where the network drops to zero while activating both the SIMs. The only way to counter this was to disable one slot, or downgrade your device.

However, OnePlus released a fix for this issue, and you can follow our instructions on How To Install OxygenOS 3.5.6 on OnePlus 2.
