BlackBerry is opening the Android OS in Beta Zone program so consumers can download and test Android 6.0 Marshmallow on the Priv smartphone. BlackBerry says space in the beta program is limited. Consumers who bought their Priv directly from ShopBlackBerry, Amazon.com, or Carphone Warehouse will be admitted into the beta program first. Those who purchased the Priv through a wireless network operator will have to wait. Registration will be open for the next two weeks. BlackBerry expects to push the first beta to devices over-the-air during the second week of April. The program will last between four and eight weeks. BlackBerry said beta testers will be expected to enable background diagnostic reporting so performance data can be analyzed by BlackBerry's development team. BlackBerry hopes beta testers will also provide direct feedback concerning speed, stability, and other factors. Android 6.0 Marshmallow adds features such as Doze and Now On Tap.
