During phonecall tap buttons for mute, numeric keypad and loudspeaker should be sliders
During phonecalls there are 3 tap buttons for mute, numeric keypad and loudspeaker.
My user experience is that these may be accidentally tapped in phone handling during phone call, especially when using with earpieces.
I genuinely think these should sliders and this can be done 100% in software so no reason to delay it's release for Jolla Kaksi-piste-nolla
