The headset only work after I turn the music app on, the services aways turns off after screen off. No multitasking, apps like gravity screen on or hold screen on, from play store, don't work, I don't try map my tracks but don't will work too. In my opinion, a big issue, by the way, 2012 smartphones makes better with less Ram. 1Gb lpddr3 can do this. Over a year and after many updates the issue continuous. Please Nokia, be reasonable.
