Motorola enjoyed massive success with the original Moto G phone. It came along at a time when reasonably priced unlocked phones were virtually non-existent, but the Moto G was soon joined by other low-cost devices. The value proposition has weakened over time as those other low-cost phones crowd the market, but the G-series has largely carried Motorola. The company didn't even bother to launch a full-fledged Moto Z flagship phone in 2018—the Z3 was a Verizon-exclusive phone engineered merely to plug into the still-unreleased 5G mod.
