If you have been using the OnePlus One for a while, you must have known about OxygenOS – the community-sourced after-market firmware for the OnePlus devices.

The OnePlus One comes with CyanogenMod as its default OS, which embeds a lot of features and regular updates. But, not everyone likes a huge list of features, that they might render useless at the end. So, for some users, stability is a factor that they like to keep at the upper hand. OnePlus definitely didn’t overlook this, and finally decided to take it to its own hand and announce OxygenOS in 2015.

Install OxygenOS 2 on OnePlus One

OxygenOS is basically AOSP compiled for OnePlus devices, with some added features. This makes the users move more close to the stock AOSP behavior, without any bloated stuff. OxygenOS doesn’t offer a huge list of customization options, like CyanogenMod. It is basically limited to changing wallpapers, navigation control, Double tap-to-wake, custom gestures, Shelf, etc.

One thing that I can assure our readers – OxygenOS is stable, with no major bugs or crashes that you have to deal with. The latest for OnePlus One is OxygenOS 2.1.4, which has been released here.

However, you must note that OxygenOS is still based off Lollipop 5.1.1, so it does make it a simple choice for the users. If you are well fond of features and tweaks, you go for CM, or else if you want close-to-stock experience and stability, you opt for OxygenOS. Now, without much waiting, we will help you Install the latest OxygenOS 2.1.4 on OnePlus One.
