All the leaks and speculation around the OnePlus 2 smartphone will be old news next week when the device launches for real, but until then we doubt you'll get a better view of the device than afforded by a bunch of images released in China.

We doubt you'll also see pictures that are more convincing than the ones that came with the certification details posted by China's official communications regulator, TENAA.

The TENAA, like the FCC in the states, requires manufacturers to submit devices for approval before they are allowed to be sold in the respective regions. Phones need to be tested to ensure their wireless communications technologies comply with set standards.

Some manufacturers don't include images of their devices to prevent leaks, but it seems that OnePlus has submitted the new handset in all its glory.

They show a device with a physical home button - one of the features that can be clearly ascertained by the pics. Some believe it might house a fingerprint sensor. Other than that, they simply show a phone that looks nice enough from the outside.
