Use your screen or back flash as a flashlight. Most homes are stocked with a flashlight which is always looked for when there is an emergency. At times the batteries are flat or the light bulb fused. Now you have the choice of using your mobile phone as a flashlight. If your phone flash is faulty or if your phone does not have a back flash, you can make use of your screen light. Working on your car, on your hiking trip , stuck on the side of the road, make use of your phone as a flashlight or emergency strobe which is currently part of your everyday carry (EDC) to light up your darkest hour.
