Weight: 136g | Dimensions: 153.3 x 75.3 x 5.2 mm | OS: Android Marshmallow | Screen size: 5.5-inch | Resolution: 1440 x 2560 | CPU: Snapdragon 820 | RAM: 4GB | Storage: 32/64GB | Battery: 2600mAh | Rear camera: 13MP | Front camera: 5MP

Creative modular accessories
Fingerprint sensor with a twist
No 3.5mm headphone jack
Big camera bump, small battery

Moto Z takes the modular accessory idea we liked so much about the LG G5 and actually makes it work with better add-ons and an easier-to-use snap-on design.

It's an Android phone that performs well right now and the potential behind its future accessories hold a lot of promise down the road. 

Usually when we talk about mid-cycle upgrades, we're strictly talking about new software. Moto Z could take on new form at any time, and new mods are still being offered a year on.

It may be the world's thinnest phone, but that comes at a cost with a reduction in battery size and the loss of the headphone jack - potential issues for some users. But if you can overlook these shortcomings then good news: you'll have a truly innovative device in your hands.

  • What's next? The Moto Z (2017) rumours are pretty thin on the ground right now, but the hottest leaks promise a metal-bodied phone with a QHD screen, coming around July.

Also consider: The only phone which comes close to matching the Z's modular capabilities is the LG G5, although it's the Moto which has the more intriguing line up of mods.
