Lenovo, which owns Motorola, last week released the kernel source code for the Moto Z Droid smartphone on Github. The move follows the company's posting of the Moto Z Droid Moto Mods Development Kit and Moto Mods on Github this summer. This is the first kernel source code made available for the Moto Z family of devices. Releasing the kernel source code seems to be another step in Lenovo's attempt to get devs to build an iPhone-like ecosystem around the Moto Z family. The Z family is modular.
