There are no fewer than four handsets in Motorola's Moto G7 family: The 6.2-inch G7 Plus, G7 and G7 Power, and the 5.7-inch G7 Play. I've already looked at the Moto G7 Plus, and Jason has reviewed the Moto G7. The G7 Play is the baby of the pack: it's smaller than its three siblings, and has a lesser specification. But it's also the most affordable at £130 ($200 in the US).
