"She reached into the bag on her shoulder and whipped out her phone. It only took a few minutes for her to call up her flashlight app..."
I'm deducting half a star for every unbelievable tech reference we get from now on. It should not take you more than 30 seconds to pull up the flashlight app, especially on newer phones that have it on the pull-down bar. Minutes means you're either an idiot or an author that has never actually used the app you are describing.
