If you’re like most iPhone 5s owners, you probably don’t use the flash on your device all that often. But if you ever need to take a picture in low light or shoot a video in a dark room, turning on the flash can make all the difference. Here’s how to do it:

  1. Open the Settings app on your iPhone 5s.
  2. Tap General and then Accessibility.
  3. Under Flash Mode, tap On.
  4. If you want to turn off the flash for future photos and videos, tap Off under Flash Mode instead of On. ..
