Using your mobile phone to check a remote control is transmitting
We have used this popular quick check of remote controls for years, but recently swapped to an iPhone 6 and suddenly it wouldn’t work/
After a bit of research, ok a LOT of research we realised that Apple removed the functionality for the rear lens to be able to detect IR beams a few models ago, however the front facing iSight camera lens normally the realm of the selfie is still able to pick up IR light.
So to check a remote control is transmitting simply point the remote control at the camera lens whilst you are on the Photo application and then press buttons on the remote control and you should see the small light beam of the IR Transmission on your mobile phone screen.
