Photos: LG shows off G5, its first-ever modular phone

LG unveiled its first-ever modular smartphone, the LG G5, at the Mobile World Congress in Barcelona. The phone comes with a B&O sound system and wide-angle lens. The entire idea behind a modular smartphone is to offer users the flexibility to replace or upgrade certain functions independently. All that one needs to do is pop out the phone's bottom and swap in new hardware features. The LG G5 comes with an always-on 5.3-inch display and is equipped with the new Snapdragon 820 processor that offers 64-bit performance and Adreno 530 graphics. Early options include a camera grip with physical buttons to take shots and control video recording. Here is the LG G5 in photos:
