    Welcome to Windows Central.

    The only infra-red* light-emitting "part" of the Lumia 730 is the proximity sensor. Hence, this will be activated when apps or phone services that require proximity information are active, such as when calling or when running a diagnostics test on the phone sensors.

    You may need to create a Windows Central account to respond to this thread.

    *- The diode also generates near-infra-red light, that's the reason why it's visible to most human eyes. Human eyes are not capable of seeing full infra-red range wavelengths.
