1. Battery tester for remote controls
Both: See if the batteries in your TV remote controls have enough power to do their jobs. Launch the Camera app and switch to the front-facing selfie camera, though in some cases the rear camera also works. Point your remote control at the camera, then press and hold any button on the remote. If all is well, you’ll see a pinkish-purplish light flickering from the tip of the remote control, the infrared beam that sends signals to your TV and other tech gear. Replace the remote control batteries if the flickering light is especially dim or you don’t see any light at all.
