mine came during the night, and my phone hadn't restarted? what if it was my alarm too? normal?
Not sure...but I think normally all security patches and full OS upgrades pretty much notify you that one is available and require user input to continue.
Happy that we got our Sept Patch to protect us from the Blueborne Bluetooth threat.
Hoping Telus can from this point on... keep up with what BlackBerry /BlackBerry Mobile send them monthly.
