There are several hands-free ways you can answer a ringing iPhone while your hands are covered by bulky, hard-to-remove gloves. You could start by wearing touchscreen-sensitive gloves. Or using a stylus. Or plugging in a pair of headphones. But what if your gloves were chosen not for their touchscreen compatibility but for their ability to keep your hands warm while the polar vortex is in town? What if you don't have a stylus or a pair of headphones quickly accessible in your winter gear and you really want to take that incoming call? There's a simple solution; just be prepared for some funny looks.
When your iPhone rings, lift it to your face, and swipe your nose across the screen to answer. (You might want to swipe a tissue across your nose first though.) The trick is to aim slightly below where you want to hit the screen and to ignore anyone who stares.
Later, when you are back inside where it's warm, consider cleaning your screen and ordering a pair of warmer touchscreen-sensitive gloves or a stylus.
