A hands-on video of the what appears to be a Google Nexus 5 prototype has leaked online, reports Engadget.

The unit matches a previous accidental photo leak from Google, but it's unlikely the final version; the software is listed as KeyLimePie, the back is marked with "Not For Sale" and the camera lens appears rough around the edges.

Nearly all the details on smartphone have already leaked online thanks to a service manual from LG. The phone was also left to charge unattended at the bar where an employee managed to capture a few video clips of the device.

Take a look at the hands-on video below. No word yet on when Google is planning to announce the device.
