My earphone speaker is working but the front camera isn’t.. Can you help?
Yes, this may seem quite simple, but probably just a faulty camera. It’s quite simple to replace, just buy a new camera and fit it as you would with a screen replacement.
Had a similar issue with a 6S, a front camera flex that appeared perfectly fine, earpiece mic (Siri mic) worked fine, proximity sensor and earpiece speaker were fine, just the front camera not working. Replacing the entire flex is probably the way to go just to be safe
