THat must be a VERY general rule as with the exception of my 80 something year old mother everyone I know absolutely uses their phones for 100 and 1 different things that ( its felt) enhances their lives. Hell EVEN my mother sits on Facebook, Instagram, video calling, instant messaging, whatsapp and dear knows what else and does much to my surprise ACTUALLY use her phone and it’s apps constructively and usefully and she’d be pissed if anyone suggested we remove those things from her now. ( even though I do have to continually remind her that not EVERYTHING she reads online is either true OR must be immediately forwarded on to me “just in case I hadn’t seen it” !!! Grrrr
