To test your remote signal, point your remote at your smartphone's camera and press any button. If the remote is working, you should see a light (usually white or purple) flashing on your phone's screen through the camera. This method works because cameras can detect the infrared light emitted by remote controls, which is invisible to the naked eye. If you don't see a light, check the remote's batteries or consider replacing the remote.
