My front camera (selfie camera as my mrs calls it) stopped working. Spent an hr in live chat with google, still unresolved. They told me to hard reset my phone to stock - which I do not want to do as setting up my work security stuff takes eons...Anyway - anybody experience this and resolve it. I don't recall changing any permissions or downloading any apps where I revoked permissions. Back camera works just fine....
Did you try booting into Safe Mode to see if the camera works there? If so, it could be another app interfering somehow.

Otherwise, there's the ever-so-slight chance that a factory reset might clear it up, but most likely you're facing a hardware problem and the phone would need to be repaired or replaced.
