Desire HD. If I activate Settings - Common - Call settings - Third party access (call monitor) phone will hot reboot on the next call (just hit Call in contact).
Do you update from old releases or do a clean install? As I mentioned, if this option is ON, the system asks to allow or deny access, if you hit "Allow" on the previous build you may avoid this bug. I think it appears on that message (allow or deny), do you got that message then you tried to replicate the issue?
Same bug on the new version (1,6,10)... Mark, please, have a look, it's a translation issue, Chinese version doesn't have that bug. I think it is on the popup window, for granting rights for call
I have the same issue on my Desire GSM, either with 1.6.3 or 1.6.10.
I cannot use Vlingo because, when it tries to open Phone to make a call, the device reboots.
Nothing changes even if I have the Third Party flag checked.
