The Mobile World Congress is an annual event where a number of smartphone original equipment manufacturers (OEM), Android ones in particular, showcase their latest flagship devices. As such, as the conference's 22 February start date edges closer, the rumour mill has begun churning in earnest. Joining the long list of anticipated debuts is South Korean manufacturer LG, with a G5 smartphone expected to debut at MWC in a couple of weeks in Barcelona, Spain.

Accompanying the expected debut of the G5 are some details about the device itself courtesy of the ever-vigilant leaker Evan Blass. According to reports, the G5 is said to have a markedly different design. One of its standout design features is said to be a unique accessory slot at the bottom of the smartphone that can detach. Although the precise reason for such a mechanism is unknown, The Verge logically concludes that it must be for battery access.

Another interesting change could involve the volume keys, which will be shifting from the back cover of the device as in previous generations. The new location is unconfirmed, but most likely will be found on the right hand side of the device.

The G5 is one of two smartphones that LG will reportedly be launching in 2016, as the company aims to refocus amid a sub-par year in smartphone sales. To that end, the company may be betting big on the G5 to take on the likes of Samsung's next S-series flagship device, which too is expected to arrive at MWC.
