I heard that someone created a tool on the N9 to interpret the head phone jack mic-gnd layout to switch between Apple jack and Android jack functionality (e. g. to let Android's volume buttons work). Is there a possibility to have this functionality on the Jolla phone too (trying to get xiaomi piston v3 headsets work complete whose volume buttons work on Android but not on Apple and Jolla).

volume buttons of iphone earphones also wont work with Jolla. So i guess the problem lies somewhere else. Also if it where to be a mic <->gnd switch then i would simply buy an adapter. But afaik android phones have adapted the apple layout for quite a while.

actually in this case apple did the right thing to change the layout to make 4pol headsets backwards compatible to 3 pol devices.

Jolla uses the newer Apple and Android (and everyone) "standard", but Jolla has only implemented the simple "button" control (which shorts the two contacts) rather than any more advanced control style. So you should get mic functionality on any new headset, just maybe not control unless it's one-button only (e.g. Coloud headphones work nicely).

The N9 was one of the last Nokias to stubbornly use the old standard (as used by Symbian and many others, before Apple re-standardised it, the swines) - would be interested as to what this tool/mod is that you found - using a stupid adaptor was one of my annoyances with the N9.
