Front camera has stopped working on my Samsung Galaxy Note8

[ChrisH]

I just woke up to find my front camera isn't working. I only realised because facial recognition unlock wasn't working so I unregistered my face then tried to register it again but got the error:

Face recognition not working
Couldn't open Camera. Try again

I rebooted but the same issues happens again.

I went to the camera and the rear camera is working fine but when I flip to the front icon I get error:

Warning
Unknown error occurred.

I typed *#0*# into the phone to enter diagnostics then selected "Front camera" which reported:

Camera failed

I have cleared cache/data of the Camera app - that did not fix it.

I will try a factory reset and, if needed, installation of latest firmware via Odin but if that fails do you think I need to return it to o2 for repair?

Good grief, what a fuss!
But at least it's working again now

I have edited my last post because I'm not sure it is working.

It works from the camera app and I got face recognition working. The diagnostics via the "Samsung Members" app show it is working (it didn't before - rear camera worked fine but front camera didn't take a picture and the whole app just froze) but when I use the diagnostic app (*#0*#) and select "Front Camera" is says "Warning: Camera failed".

So, to all intents and purposes, the camera works for my standard usage, but the diagnostics failing has me concerned.

I think I need to find out if anyone else can try using *#0*# and see what happens for them on the same phone.

Probably still a good idea to get Samsung to look at it once you have your proof of purchase from o2?

I think I'll do just that
