How to factory reset phone when I can't find the factory reset option? 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.)
Posting this as answer in case anyone else runs into this.

It turns out that I had manually disconnected my Google account years ago, when I switched to a new phone. By reconnecting the Google account, it added the Privacy section (including the Factory Reset option) back into the Settings app. Once that option became available again, the reset worked with no problem.
