    I can't start camera app/take photos or use any other app that uses camera functionalty. I always get the message "unknown error". It all started after updating to Android oreo on my One Plus 3.

    I have the exact same problem - after the upgrade the camera stopped working. doesn't work with any other camera app either. i had the camera chip replaced and it has the same issue. so it's not a HW issue

    just do a factory reset.. it help 10000%.. i do it 2x .. One app called Os X theme do that bug with camera and flaslight.. factory reset helps.. ( your personal data dont remove just system)

    Oh, so that was the problem! I also installed OSX theme to try. Since then my OP3 camera hasn't been working. Could there be any other method than factory reset?

    i tryed almost everything . ( malware scan, ccleaner, cache cleaner, phone doctor. etc..) nothing helps.. factory reset delete my apps but it dont delete my photos, videos and music. .. in my opinion ,after factory reset phone runs smoother.. but now i have another problem... i have about 100+ games and on 2 of them i have blackscreen.. i dont k now where is the problem. On android 7.1. they worked fine but after 8.0 and factory reset i have blackscreen. One of them is called "assemblr" you can try it if it work or if u have too blackscreen before factory reset :D
