Pick the Razr 50 if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are weight, pixel density, screen size, among others.
Both ship with comparable main camera, 5g support, front camera, so those specs do not separate the two — focus on the differences below.
