Gizmochina 1 of 2 Lava myZ According to Lava, myZ is the world’s first customizable phone. It essentially gives you the choice of choosing your own version of RAM, ROM, Cameras, and Color while purchasing. That is, you can mix and match the available features on your own to get a customized version of the device. Generally, manufacturers sell a smartphone with fixed specs. However, it markets different storage variants at different price points any of which you cannot upgrade or change in the same device unless you have a faulty device. Lava’s myZ eliminates at least half of that taboo.
