There's little we don't already know about Google's new Nexus phones, but another leaked image of the 2015 Nexus 5 has been posted online for good measure, Digital Spy reports.

The photograph obtained by AndroidPIT just so happens to offer our clearest look at the rear of the LG-made handset so far.

A fingerprint sensor, raised camera lens and prominent Nexus logo are all visible in the picture, which lines up neatly with previous rumours.

The 2015 Nexus 5 is expected to include a 5.2-inch Full HD screen, a Snapdragon 808 CPU, 4GB of RAM and a USB Type-C port for faster charging and data transfers.

The source speculates that the device launch with a $400 price tag, which suggests the One Plus 2 could have some serious competition on its hands at the budget end of the spectrum.

Google is expected to announce the device alongside a new Nexus 6 from Huawei at a press conference on September 29.
