# Controls

## Anatomy

  * In Control Center, a control displays its symbol and, at larger sizes, its title and value.

  * On the Lock Screen, a control displays its symbol.

  * On iPhone devices with a control assigned to the Action button, pressing and holding it displays the control’s symbol in the Dynamic Island, as well as its value (if present).

## Best practices

**Offer controls for actions that provide the most benefit without having to launch your app.**

**Update controls when someone interacts with them, when an action completes, or remotely with a push notification.**

**Choose a descriptive symbol that suggests the behavior of the control.**

**Use symbol animations to highlight state changes.**

**Select a tint color that works with your app’s brand.**

**Help people provide additional information the system needs to perform an action.**

**Provide hint text for the Action button.**

**If your control title or value can vary, include a placeholder.**

**Hide sensitive information when the device is locked.**

**Require authentication for actions that affect security.**

## Camera experiences on a locked device

**Use the same camera UI in your app and your camera experience.**

**Provide instructions for adding the control.**
