Recieved my samsung s10 about 2 days ago and haven't had chance to check my front camera out as it keep saying camera failed when I switch to it! Does anyone know why this is or how I can resolve it
Try a soft reboot by turning the phone Off and On.
You could try going into Settings_Apps_Camers and choose Reset Settings.
And there is a Hardware test:
go over to your dial pad and type in *#0*#, this will bring up a number of tests.
Personally as the phone is so new I would also consider going back to source and asking for it to be swapped out @Chlo2
My advice comes from being a UK Samsung Phone Owner.
I have no affiliation with Samsung.
