Motorola Moto G4 Plus review:

  The Motorola Moto G4 Plus and Moto G4 are extremely similar Android phones that perform far better than you'd expect for the price. In fact, these fourth-generation entries in the Moto G line effectively redefine value in the smartphone realm, moving from merely "good enough" to "amazingly good for the money."

Both phones offer a bevy of solid features, including 5.5-inch full HD screens, capable octa-core processors and decent 3,000mAh batteries, including some notable niceties -- expandable storage and water-resistant bodies -- not found on current iPhone models that retail for three times as much.
The Moto G4 Plus edges ahead in the specs race with a fingerprint sensor and a better camera. Unfortunately, though, it doesn't include NFC compatibility for Android Pay purchases at real-world retailers.
For that reason, we're more inclined to stick with the base G4 model, which costs just $199 or £169 at its base configuration. But if you value scanning your finger to unlock and zooming in to photos for more detail, the Plus may well be worth the modest price increase -- an extra $50 or £30.

What's the price difference?

Motorola doesn't make it easy to give a direct comparison between the US and UK markets. That's because the phone is available in slightly different configurations at retailers (like Amazon) and the company's own Moto Maker site (where you can configure customised versions). But the bottom line is that both phones have amazingly low starting prices for what you're getting.
The base 16GB G4 is $199 or £169. Adding $30 or £30 gets you a 32GB version at Motorola's website. (For the equivalent price in Australian dollars, please see the spec chart at the end of this review.)

The base 16GB version of the G4 Plus starts at $249 or £199. For £30 more (£229), those in the UK can get a 32GB version (not currently available in the US). The Plus tops out at $299 or £264 for 64GB, which also doubles the on-board RAM to 4GB from 2.
The bottom line is that the Plus adds a couple of "nice to have" features, especially if you prefer to unlock the phone with your fingerprint or like to zoom in to your photos for greater detail. But the lack of NFC and full Android Pay features makes us inclined to stick with the baseline G4 model.

What's different between the G4 and G4 Plus?

It boils down to two main things. The G4 Plus has a larger, 16-megapixel (versus 13MP) camera and a fingerprint scanner that unlocks the phone. What the Plus also allows you to do is spec up the internal storage capacity up to 64GB, which also snags you double the RAM (4GB in total).

  If the fingerprint scanner had worked with point of sale Android Pay, the G4 Plus would be an easy recommendation over its less expensive twin. But its lack of NFC means you won't be paying for cabs and Chicken McNuggets at the register.
One other problem with the fingerprint sensor is that it looks like a home button and I regularly found myself pressing it to leave an app -- which does nothing, as it purely functions as a scanner.

But the other specs are the same?

Yep. Both phones have bright, sharp 5.5-inch displays with full HD resolutions (1,920x1,080-pixels). They're the same physical size and have the same processors, 3,000mAh batteries and 5-megapixel front-facing cameras. They're both water-resistant (they can take a dunking), and have microSD expansion slots (up to 128GB) for cheap and easy storage upgrades.

I use a lot of social networks. Can it handle Snapchat?

Absolutely. Its octa-core processor is well-suited to everyday tasks like WhatsApp messaging, Tweeting and Snapchatting. Even photo editing in Snapseed handles just fine. There's not much you'll need to do on a daily basis that this phone won't be able to manage.

What about gaming?

Lightweight games like Two Dots or Crossy Road will play fine, so the casual mobile gamers wanting to kill time on the commute are adequately catered for. More hardcore gamers among you will want to consider a handset with a bit more grunt behind it.
