As far as I know Android 10.7 is the Android Auto application version and not the Android operating system, so it’s a marketing tactic. The question is then what’s the real Android version? Also posted related question here I Need Your advice for watch replacement (old Kospet Prime) - #11 by Edwin_Mennes where Kospet Prime 2, Kospet Optimus 2 and LEMFO LEM15 are listed with those versions.
I’m just curious what to expect.
