Maybe this is just me being daft because I'm still new to Apple but I just got back home and took my phone out to use and on the lock screen at the bottom left corner was the calculator icon. I entered my fingerprint and double pressed the home button expecting to see the calculator app open but it wasn't. Instead at the bottom of the screen was the calculator icon and some text next to it saying "arrived at home" or " back at home". I tried to screenshot it but it's now gone away. This has never been there before and I don't think I've changed anything to make it appear there, so does anyone know where it came from or why?
