6. Wipe data / Factory Reset

CyanogenMod 12 use Android 5.0.2 and 12.1 use 5.1.1, you need to make a factory reset.

I was expecting that "Audio in calls on 2nd SIM" would be fixed.

It seems I will have to stick with original 4.4.4 for a long time.
there will be no fix for 2sim ( almost all CM Roms have this bug )
