Front camera not working properly

Just recently my front camera and light have stopped working. I know this is a software fault somewhere as the only app that works the phone and light is Facebook. The camera app and WhatsApp and any other app fail to turn on the camera. The selfie camera is fine.

I think this happen when the upgrade of 14.4 came about. I’ve done the reset and off and on stuff as well as closing all app and restricting the camera for all apps in the settings. Has anyone else got this problem?
