Where is the factory reset button on Android 4.0.3? I would like to do a factory reset of my Android phone. All guides on the internet I read show a factory reset button under the Privacy tab in Settings. However I don't have this button.

Where is it hidden?

I have Android 4.0.3 on an HTC one phone.
The actual setting is:


Settings
Storage
Towards the bottom is the factory reset option
