The impressive LG G2 was the surprise smartphone hit of 2013, but the decision to place the volume buttons on the back of the device wasn't so popular with everyone.

Judging by a leaked snapshot, unearthed by GSM Arena, LG plans to keep the design feature in place for the forthcoming LG G3, but with some refinements.

The shot appears to show flatter volume buttons, which will please potential buyers who swerved the LG G2 because of the protruding design and the inability to it flat.

While the photo doesn't show an awful lot more, there does appear to be an undefined, additional sensor next to the camera lens. The sensor's purpose isn't clear at this time.

Key specs

Beyond the handset itself, the photo also features a notepad appearing to outline a couple of key specs.

It mentions "OIS+" which we presume means optical image stabilisation, while also mentioning 16GB and 32GB storage options. The presence of the text 2GB and 3GB surely makes reference to on-board RAM.

Previous speculation has suggested the LG G3 will offer a tremendous array of top-line specs, including a 1440 x 2560 2K display, an octo-core Odin processor, built by LG itself, a 13-megapixel camera and Android 4.4 KitKat.
