I have seen that also. But then there are those of us, myself included along with all 3 family members, that have never had a Bluetooth issue with a Z series phone. Our phones have been through multiple version updates and one replacement phone, and Bluetooth has worked flawlessly. I'm not trying to be a downer or crash the party, but I just don't see a new version of Android fixing a Bluetooth problem that doesn't affect every phone out there. If it affected every phone, then the Android version could be blamed. But for every user that posts Bluetooth issues on Forums, there are probably double as many that have no issues.
