I can affirm that beating devices into submission is possible :-) We support iOS too with PTT headsets, Airpods, and other BT headsets and that gets interesting in different ways.

Based on my experience, it seems hardware vendors are not treating soft-keys as a core requirement and are generally bolting support on and in some cases omitting it. It's as if the requirements didn't include third party app support beyond the carriers PTT products that they OEM.

Indeed! Add to this older Android OS support, Classic BT devices, BT LE devices, combined LE - Classic devices (and each with their own firmware quirks), audio routing, undocumented APIs ..and the list goes on and on. PTT is a wonderful world :)
