I have an old Samsung Galaxy S3 that's been sitting in my desk for years. I wanted to clear it off to give to a friend, but I'm not seeing the factory reset option anywhere. All guides I can find online indicate that it should be in the Settings app, but it's not. (There is no Privacy section anywhere in the Settings app.)
Is there any other way to factory-reset a phone? It's on 4.3 (Jellybean), according to the About Device screen. (I've tried to get to recovery mode with the power/volume down key trick, but it doesn't work; just continues to boot normally.)
