Lenovo's modular Moto Z and Moto Z Play phones launched with 4 mod options

Snap on a bigger speaker, a better camera lens, another battery or even a projector to enhance your mobile experience. Motorola's two new modular phones could change the smartphone in a big way.

SINGAPORE - Lenovo's premium Moto smartphones, which feature interchangeable modules that snap on to their back, were launched here on Thursday (Oct 27).

The Moto Z and Moto Z Play allow for a host of Moto Mods, or modules which boost features such as music playback or photo-taking, to be attached to them. These modules snap onto the back of the Moto Z and Z Play using magnets and work immediately, without the need to power down and reboot the phone.

The Moto Z ($899, without contract) is a thin phone, coming in at only 5.2mm thick, with an all-aluminium body and 5.5-inch quad-HD Amoled display. It is powered by a Snapdragon 820 processor and features a 13-megapixel rear camera and 5-megapixel front camera.

The Moto Z Play ($699, without contract) features a less powerful Snapdragon 625 processor but comes with a 16-megapixel rear camera.

Both the Moto Z and Z Play run near-stock Android 6.0.1 Marshmallow mobile operating system.

Users who want to boost their phone's functionality can do so with the modules. Four interchangeable modules are available at launch: a camera module made by famed Swedish company Hasselblad, a speaker module by JBL, a projector module and a battery pack module.

The $459 Hasselblad camera add-on is the most expensive module available, but it lets the phone act almost like a point-and-shoot camera due to a physical shutter button. It also provides a 10x optical zoom and a xenon flash for better lighting.

Another module is the Moto projector ($399), which allows users to beam their home screen, photos or videos onto a wall.

Audio fans who want a portable speaker option can opt for the JBL speaker mod ($139), which boosts the volume and body of music from the phone.

Lastly, the Incipio Power Pack ($139) provides 20 hours of battery life for heavy users.

Both Moto smartphones are available here from Thursday at Lenovo stores and online retailers, but telco availability has yet to be announced.
