I have a user with a new Blackberry 9650. When he enables the keyboard lock, the Blackberry no longer rings or vibrates when the alarm goes off. If the keyboard lock is not enabled, the alarm works.
I have swapped his Blackberry with another one, and this 9650 has the same problem. I have also tried downgrading the device to the older 9650 firmware, which did not resolve the issue either.
Thanks so much!
