Question
Dear ZZ

Is it possible to automate Smartphone torch operations I.e switched on in darkness and switched off in broad daylight?.

Thanks
Prashant

Answer
Good question. I don't see why not.  Technologically it is not difficult.

I have an older ZTE smartphone that lights up the buttons on the bottom row of the front panel when it is in a dark room to allow easier view of the owner in poor light conditions and saves battery power being off when light is strong.  I think there are many other makers with similar ideas.

That is my thought.

Cheers.
