[Update]:There’s a possibility that the leak is actually for HydrogenOS, which is a different ROM being made specifically for Chinese OnePlus One models.
It would make sense that OnePlus wants to make a separate ROM for their home region as Chinese designers tend to prefer these sorts of user interfaces over your typical Android overlay. It would appear we’re still a bit in the dark as to what OxygenOS will look like, but we’re glad to see that OnePlus might be far along on either front.
There isn’t a huge blowout of information here, but we do get a glimpse at the ROM’s beautiful weather app. It doesn’t look too busy in its current state and does what it’s there to do: give you the current temperature and weather conditions. It looks damn good doing it, though.
We also get a look at some sort of categorical app drawer that might be featured. A collection of favorites sit in their own space above, tools have their own sections, while you find all the games grouped into their own little space. We’re not sure if this is the primary way to access apps on OxygenOS or just an alternate view for those who prefer something a bit more organized.
The design seems to be trending toward “flat” if these few screenshots are anything to judge by, though that isn’t surprising considering flat is all the rage lately. Unfortunately that is the extent of our knowledge right now.
It’s said OnePlus hired the entire team behind IUNI for this specific purpose so whoever’s responsible for designing this thing certainly has enough of a resume to make a truly unique user interface to sit atop Android. In the meantime you’ll soon be able to enjoy Lollipop in its more natural form with an upcoming upgrade to CyanogenMod in the very near future.
