The highly anticipated OnePlus 3 smartphone has popped up in an official certification showing off the device's squared-off metallic build. There are plenty of specs confirmed too.

The OnePlus 3 has been the source of plenty of rumours as we near its virtual reality release event expected on 14 June. Now the Chinese telecommunication equipment certification center, or TENAA, has leaked the details early.

The photos, shown above, clearly fit with rumours so far showing us a metallic build and an angular finish. Otherwise it looks very similar to a certain HTC smartphone, perhaps only thinner and with minimal side bezels.

The listing also has specs to go with the photos, which are in line with leaks from other sources so far. The OnePlus 3 is expected to come with a 5.5-inch 1080p display, Qualcomm Snapdragon 820 CPU, 4GB of RAM and 64GB storage.

On the rear should be a 16-megapixel camera while the selfie snapper is listed as 8-megapixels. Everything should run on Android 6.0.1 Marshmallow and be powered by a 3000mAh battery.

While the expected 14 June VR launch event date seems solid, pricing has not been announced or leaked, yet. The OnePlus was £230, while the OnePlus 2 was £239 and £289 for larger storage capacity. So the OnePlus 3 hitting the £300 mark would not be a shock.
