Today OnePlus has finally released their new Android ROM for the OnePlus One. The OnePlus One originally shipped with CyanogenMod 11S, and in most regions there will still be an update to CyanogenMod 12S. The development of OxygenOS began after conflict arose between OnePlus and Cyanogen, with some of the conflict coming from to an exclusivity agreement between Cyanogen and Micromax in India which prevented OnePlus from shipping future updates and devices running CyanogenMod.

OxygenOS is OnePlus's solution to the problem of relying on another company for software. It's a version of Android for the OnePlus One which is built by OnePlus themselves, giving the company more control over their device as a platform. However, the update will not be coming to most devices as an over-the-air update. Users who wish to install OxygenOS at the moment will have to download the ROM from OnePlus, unlock their bootloader, and flash the new recovery and ROM via fastboot. Thankfully, OnePlus has provided an installation guide on their forum for any users who are not familiar with flashing custom ROMs on Android.

    Nope, not in the slightest - OnePlus just nicked the name, but judging by the size of their ROM download, the name Oxygen isn't correct - LeadOS would be more appropriate. :p

    I didn't even realise that an XDA forum wiki existed for Oxygen...it was fun developing that...

    Is there a review of the new OS planned?

    It's stock Android L, but it would be useful to hear how stable or buggy it is.

    I'm going to take a backup and install it today. As a long time Nexus user, I'm fine with stock, but I have a sneaking suspicion that future updates will come out quicker for OxygenOS than Cyanogen can manage. I guess we'll have a better idea when the 5.1 updates come out.

    good. they were all a bunch of filthy sellout thieves who stole a bunch of contributed work meant instead for the benefit of everyone, not meant for the benefit of a few who had control of the name 'CM' anyhow.

    It's 5.0.2, but with some annoying quirks, like the inability to set a new home screen (or reset which screen the home button takes you to), or having to reboot the phone to get your widget window to update after several new apps are installed. Coming from CM11, those are a bit annoying to adjust to. As is that persistent search bar at the top of every screen. And the Google Now page that you cannot link to the home button long press, as it is in CM11.

    Otherwise its a fast, nice rom that doesnt seem to have any major game stopping bugs (yet). (Ive only installed it this morning, so time will tell.)

    As a follow up: Battery life is atrocious with this rom. What used to last all day now barely survives 8 hours of light usage. Think I'll be going back to CM as well.

    Same situation with battery life here. On a side note, I like that they distributed this as a recovery flashable zip. I'll take another backup with OxygenOS on it so I can flip/flop between the two easily as updates come out.

    I installed it a couple of days ago, but couldn't get any service (apparently this is a known bug). I went to CM12 nightly instead, which has been running fine for now.

    One has to wonder: How does someone that buys a device like this, regardless of how cheap it is, deal with an experience that is so poor and inexcusable? Imagine something like this happening with regular companies, like Apple, Samsung, and so on.

    A situation like this just sets in stone how amateurish One Plus and their products are. Certainly nothing more than toys for young men to play with. And that is strange, because smartphones are supposed to be personal objects that help you during the day, and never fail you.
