Your Smartphone Tests TV Remote Batteries!

If you’ve ever found your TV remote not working even after replacing the batteries, you can check if the issue is with the remote itself by using your smartphone. Here’s how….

Open your camera and tap the icon to bring up the front-facing lens, shown below highlighted in yellow.

Now point your TV remote directly at your screen and press a button. If you see a red light emit from the front of the remote, that means that the infrared signal, which is undetectable to the naked eye, is indeed working. See the small purplish shape in middle of the remote in the below picture? That shows it’s working.

Blame the batteries and replace with those you know are fresh.
