Android One smartphones might be off to a slow start in terms of sales, but it also appears they are also off to a slow start in terms of updates. According to one of the manufacturers, Spice Mobility, the Dream Uno will receive the Lollipop update by the end of January 2015. More than likely, the Micromax A1 and the Karbonn Sparkle V will also get the update around the same time.
Since all Android One phones sport hardware specified by Google and updates come directly from them, you would think the update would be a little quicker. According to sources within Google, the update is ready, so it’s possible that it could start rolling in December. I guess only time will tell.
