The first manufacturer (after Nexus devices of course) that comes to mind when speaking of developer-friendliness has to be OPPO. In fact, OPPO’s N1 is the world’s first phone to ship with CyanogenMod.
In the 12 minute video, OPPO’s ambassador for Hong Kong showcases his OPPO N1 running CyanogenMod 10.2. Although the video is in Chinese which not all our readers speak, a lot can be made out from the video itself. The device is seen performing quite smooth on CyanogenMod, which is said to be a very resource-effective ROM for phones.

What’s heartening to see is the support for OPPO N1-specific settings (like O-Touch) which the ROM is shown to support.
