Secret-keeping is not the technology industry's strong suit, and ahead of the July 27 launch of the OnePlus 2, images of the phone have appeared on a Chinese certification database.
As first reported by Engadget, four photos were published by TENAA, which, like the FCC, registers and certifies devices.
Based on these images, it looks like the OnePlus 2 has a physical home button—which perhaps supports a built-in fingerprint sensor—rather than the light-up icons on the OnePlus One.
A new front-facing camera, meanwhile, now resides on the opposite side of the phone's earpiece speaker. Little else seems to have changed on the facade.
Likewise, a non-descript back panel looks similar to the current model, with an ever-so-slightly lowered camera and LED housing—which features what 9to5Google identified as the new autofocus feature.
Perhaps most intriguing are the side views, which suggest the addition of a mute switch (think Apple's iPhone), or maybe a dedicated camera shutter button (think Nokia Lumia 1020), as 9to5Google speculated. The normal volume rocker and SIM-card slot are also present.
Details about the OnePlus 2 have been trickling out from the manufacturer, which recently confirmed a Qualcomm Snapdragon 810 processor and a USB-C port. But the company was waiting to release full details at a VR-inspired July 27 launch event.
Starting at 10 p.m. ET on Monday, folks around the world can stream the OnePlus 2 launch in virtual reality. Of course, you'll need a VR headset, like Google Cardboard or the sold-out OnePlus Cardboard, to watch the presentation in true form.
The Chinese smartphone maker has not yet announced exact pricing details, but earlier this month, it put to bed rumors that the next-gen handset will cost up to $200 more than its predecessor.
