Powerful, waterproof and affordable: The new Moto G4 and G4 Plus

Motorola has given its popular Moto G series a spit and polish (that's not literal spit in the photo). There are now three Moto Gs to choose from -- the standard Moto G, the Moto G Plus and the Moto G Play, the latter of which is only available in the US.

The G and G Plus are physically identical, and are only separated by the beefier camera and fingerprint sensor found on the Plus. Both models will be going on sale in the UK and US in June, costing £169 for the Moto G and £199 for the G Plus. Motorola hasn't said how much they'll cost in the US or Australia, but the Moto G's price converts to about $245 or AU$335, while the Plus' price converts to about $285 or AU$395.

Both the G and G Plus have 5.5-inch displays, which is a big boost from the 5 inches of the previous model.

They run the latest Android 6.0 Marshmallow software, without any cumbersome manufacturer skins applied.

There's no physical home button on the front of the Moto G.

This looks like a home button on the G Plus, but its only function is as a fingerprint scanner.

While the Moto G has a 13-megapixel camera, the Moto G Plus has a 16-megapixel camera with laser-enabled autofocus.

Even with the larger displays, I found both phones quite comfortable to hold.

They use Micro-USB charging ports, rather than the more recent USB Type C.

The back panels are flat, rather than rounded as they were on the last generation.

You can expand the storage with microSD cards.

That's a lovely marshmallow.

Both displays have full HD (1,920x1,080-pixel) resolutions.

They'll be available in a range of colours using Motorola's online Moto Maker tool. That's good, as this black model looks pretty dull.
