The search giant did say the first handset would arrive in "the fall" of 2014, but a new report from the Economic Times reckons it will touch down in October.
Apparently Google is going to push the $100 (about £60, AU$106) smartphone in a big way in developing countries, such as India, with a huge marketing campaign planned for the arrival of Android One.
Google's low cost X factor
It's not clear what the final specs of the first Android One device will be, but it's expected to be produced by Micromax and an example unit at Google I/O sported a 4.5-inch screen, dual-SIM, an SD slot and FM radio.
The Android One program is unlikely to make it into more developed markets, certainly in the short term, but if it proves a success - and a competitive rival to the Nokia X - we could see Google widening its availability.
