ringtone change required reboot [released]
I have installed the unofficial codecs package from the warehouse, so that I could use the ringtone from my N900. I select the ringtone and hear the jolla play it. When I get the next call it still played the jolla-theme-music.
I reboot phone just in case, then the next call after reboot uses the n900 ringtone I had selected.
Had been nice if you didn't have to reboot after you changed ringtones and other signals.
