It's all but confirmed that LG will officially unveil its new flagship smartphone, the LG G5 on Feb. 21 at a press event in Barcelona. New diagrams for the handset have just leaked and confirmed its new design, button placements and dimensions.

LG has been stepping up its game in the smartphone world in the last few years and shows no sign of slowing down. The company has delivered handsets with unique features to set itself apart from rivals, such as the LG G Flex 2, which features a 5.5-inch curved OLED display and "self-healing" rear case that can remove small scratches.

The company's current flagship smartphones, the LG G4 and the LG V10 have also been hit with smartphone fans due to gorgeous quad-HD displays, powerful internals and high-end cameras the company is known for.

The flagship status for the LG G4 is now numbered, as LG is widely expected to unveil the LG G5 at a press event to kick off at the Mobile World Congress on Feb. 21. We recently reported that LG is planning on delivering a first-of-its-kind modular design for the handset, which will allow users to slide the bottom of the metal case off and access a drawer to replace the smartphone's removable battery. The handset also had some of its specs and model number revealed through its User Agent Profile.

Now, there has been another LG G5 leak, which shows a diagram of the smartphone that includes its overall size and dimensions, new design, and camera and button placements. According to the diagram, the LG G5 will be thinner, taller and wider than the G4 and will measure 149.4 x 73.9 x 8.2 mm.

LG has repositioned the G5's volume keys to the side of the smartphone instead of the rear like the G4. LG has kept the power button on the back of the device, which now includes a built-in fingerprint scanner, similar to that of the LG Nexus 5X. The handset's 16-megapixel rear camera with dual-LED flash and laser autofocus is also visible in the diagram.

We'll keep you posted on any new LG G5 details as they become available.
