All three also have a dedicated Google Assistant button and sport DTS:X 3D Surround Sound, a high-end audio technology that simulates a 7.1-channel surround sound system. The Q60 and K50 are powered by a 3,500mAh battery, while the smaller LG K40 is outfitted with a 3,000mAh battery.

The big differentiator among the handsets is the camera setups. The Q60 and K50 both feature 13MP front-facing cameras, but the Q60 has three cameras on the back: a 16MP with Phase Detection Auto Focus (PDAF), a 5MP for Super Wide Angle, and a 2MP shooter with Depth Sensor.
