This is driving me crazy. If you point the OEM remote at your smarphone's camera and then press a button on the remote, you can see a light flashing on the smartphone's screen when the remote sends an IR command.

When I press the "TV" button on the OEM remote for the Sony KD-65X85K television, sometimes I see the flash of light and sometimes I don't. Either way the command gets sent to the television. The reason I care is because I'm trying to teach the command to another remote, so I need to find a reliable way to get the OEM remote to send an IR command when I press the "TV" button.
