It seems that Motorola did not reveal yet everything about its upcoming Moto Z smartphone, but new leaks just appeared online to give us more details about the device.

According to Android Authority, a photo leaked online displays three back plates called "MotoMods" by Motorola. Speculations claim that this would be the company's take on the whole modular idea that has become quite popular lately. For instance, in the G5 smartphone model, LG has decided to make its bottom removable, allowing various modules to be attached to the mobile device.

It is possible that Motorola is making back plates that could be switched at will. The front plate improves the camera with a dedicated shutter button, additional lens and some flash technology. The one in the middle could be a sort of kickstand. As for the black plate, its use does not seem easy to guess.

It is speculated that these accessories are made for the upcoming Moto Z device, but other details continue to be scarce. Besides the modular plate system aimed to allow easy personalization and extending phone's functionality, tech analysts expect that the Moto Z will come with improved specs and all-new design.

According to rumors, there will be two versions of the device. The high-end handset could come with a Snapdragon 820 processor and 3GB of RAM, while the more affordable version could be equipped with a 3,500 mAh battery and a Qualomm Snapdragon 625 processor.

According to Trusted Reviews, the Moto Z will be a direct replacement of Motorola's Moto X family. This means that the upcoming device might follow similar upper to mid-level pricing. The price of the Moto Z mobile device will depend on the precise model and design specification.

Motorola is expected to make an official announcement on its Moto Z device on June 9. Until then, these are nothing but leaks, speculations and rumors. The official launch of Moto Z is expected on Aug. 24.
