.....or my iPad.
If I lose my mobile, which I do often, I can ring it from my landline and track it down easily enough. Last time the dog was lying on it. If I lose my car keys I can shout and they whistle back to me.

It's no use activatimg the 'locate my device' option as all it tells me is it's either in my house (or in the neighbours house!) . Same for my iPad.
Surely it ought to be possible for these computer geeks chappies to devise some sort of ' here I am' signal?
To think that London, or anywhere else for that matter, does not belong to any one demographic
