BlackBerry is preparing to roll out Marshmallow to Priv beta testers who have opted into the program and completed necessary enrollment steps. The company has confirmed in the beta zone that Marshmallow will be released to the program from today.
So, how will you receive the update on your Priv? Should you be in the beta, you'll receive Marshmallow as you would a normal system update. Either the OS will ping you with a notification to upgrade, or you can check manually by heading into Settings > About phone > System updates. Be patient if the update isn't quite hitting your handset yet as only some participants will receive it today.
"Some participants will start to receive Marshmallow software tomorrow (Wednesday, EST). We will take a similar approach to how we brought people into the program when rolling out the software update: start with a small group, monitor for any critical issues, then expand to larger and larger groups. We expect to have everyone updated by the end of the week."
As a side note, be sure to have diagnostic reporting enabled on your Priv. Android 6.0 will not be fired to your Priv if you have not completed this step or have disabled diagnostics. Haven't signed up to the beta program yet? There may still be time for you to get on the wagon before the rollout commences.
