Here’s an instant personality test. Get your iPhone out and bring up the keyboard. Tap the emoji button and look to see what your most frequently used emoji is. It’s the one at the tippy-top of the list (unless you’re using an Android device, which will show your most recently used emoji, not your most frequently used emoji). This is the emoji you go to time and time again when communicating with others. And this byte-sized blip may say more about you than you think.
