If you own an Apple iPhone there are many extra options tucked away in the main settings app. It is worth ploughing through all the menus to see what else you can change / improve.
One of my favourite options to turn on is having the rear camera flash for incoming notifications and when the phone rings.
To do this open the main settings app, general, accessibility and scroll down and toggle on “LED Flash for Alerts”. A word of warning, in a dark room, the flash is rather powerful. However, I quite like having this on when I am listening to music as it means I won’t miss any new notifications as they arrive.
