Android One is a reference platform — it’s a set of rules that device makers can follow to make low-cost phones.
The first Android One devices will be produced by Indian manufacturers this fall. An example device that Google demonstrated this week featured a 4.5-inch display, support for two SIM cards at once (an important feature for many in developing markets), an SD card slot, and an FM radio. Critically, it is said to cost less than $100 to make, far less than the cost of most smartphones sold in the developed world.
Google isn’t just controlling the hardware with Android One, either — it’s also making sure the devices run the latest versions of Android.
Micromax, Karbonn Mobile and Spice Mobile will also be making Android One phones.
