OnePlus have big plans for 2015 from the launch of their own ROM, new devices and even an R&D department in Europe.
OnePlus might be a China based smartphone maker, but their international and Chinese teams do work independent of one another, this has worked out really well and means that each team can focus on developing their products for their own target market.
The fact that OP will release two ROMS, H2 OS for the Chinese market and Oxygen for the international market is a great example of this.
The OnePlus team plan to build on this over the next year with a new European based R&D division that has been confirmed by OnePlus founder Carl Pei in a recent Google+ post.
OnePlus are known for moving fast, so although we don’t know where or when OnePlus European will being we can be sure it will happen fast.
