Actually that would make a lot of sense, esp in your situation.

Not using the big button things here btw. And not dealing with more than general old age (including it seems my own approaching old age... etc.) infirmities here (though dad can have short periods of confusion that we believe are a past stroke related and more likely to come on when tired or stressed). Other mobile phones in use are my old ACE 2, handed down to mum and a basic Nokia which will go 2 weeks (I gather the old famous now revamped does more) left on in the car without charging.
