I bought the BlackBerry KeyONE at Digitec and I receive Android Patches every month but most of the time between middle and end of month. Don't know exactly who has to "approve" these patches - Blackberry official blogs state that the carrier has to approve it - don't know if it applies for devices bought at Digitec without carriers abo.
Thanks for the answer. Unfortunately, I'm still sitting on the September update. That should not be. Yes, Blackberry devices from your shop should get updates regularly, I think they have build number BA100-1. My DTEK60 from Digitec has the number BA100-2, which apparently received the update later.
