The OnePlus 3 will be launched next month at a virtual reality event and now leaked details of the phone's hardware and software reveal just what the Chinese company is planning to show off.

Sources with knowledge of OnePlus' plans have confirmed to International Business Times that details leaked on Twitter about the company's upcoming OnePlus 3 smartphone are accurate and the smartphone is currently scheduled to be revealed on June 14.

Earlier this week, OnePlus said it would once again launch its flagship smartphone at a virtual reality event, giving away 30,000 VR headsets to fans, though the company didn't reveal the exact date of the launch at the time. However, a live chat agent on OnePlus' website revealed to one customer that the event is scheduled to take place on June 14, a date which IBT's sources have also confirmed. However, details are still being finalized and the date could change.

An image of the new smartphone that was leaked last week suggests the phone has been dramatically redesigned and will take design cues from HTC's One range.

The leaked specs were posted on Twitter by Evan Blass, a journalist with a strong track record of getting access to details of smartphones ahead of their scheduled launches. The OnePlus 3 will, like last year's OnePlus 2, feature a 5.5-inch screen with a relatively low resolution of 1920 x 1080 pixels. The difference this year is that the OnePlus 3 is expected to move from LCD display technology to AMOLED, which promises better contrast and deeper blacks.

The OnePlus 3 is also set to come with Qualcomm's latest mobile chipset, the Snapdragon 820, which can be found in a range of this year's flagship devices from the likes of Samsung, LG and HTC. It is not clear how much RAM will be paired with the chipset, but previous rumors suggest OnePlus would release two versions of the phone, one with 3GB of RAM (and 32GB of storage) and another with 4GB of RAM (and 64GB of storage).

One of the most interesting aspects of the leak is the mention of Android N, the latest version of Google's operating system, which is still under development. Sources speaking to IBT could not confirm if the OnePlus 3 would launch with Android N, but it seems unlikely given Google's final version of the software is still a few months away. However, the fact that OnePlus is testing Android N with its own software suggests the company is planning to support the new OS when it is finally launched.

Other confirmed specs include a 16-megapixel rear camera, NFC support for mobile payments (something that was missing from last year's model) and a USB-C for data transfers and charging. The OnePlus 3 is thought to feature a fast-charging technology borrowed from its parent company Oppo, which could charge the device in under 15 minutes — though IBT's source could not confirm this.
