Turn On iPhone Screen Distance and Clear Its Alert Without Disabling It
A Screen Distance alert does not require you to switch the feature off to get back to your iPhone. Move the phone farther than 12 inches from your face, then tap Continue. The feature remains available to warn you again during later close viewing.
Check the camera requirement first
Apple’s current Screen Distance instructions require a TrueDepth camera and iOS 17 or later. TrueDepth is the camera system used for Face ID. Having a newer software version alone does not satisfy the hardware requirement.
Apple describes the feature as detecting prolonged viewing closer than 12 inches. The support page does not specify an exact number of seconds or minutes before each alert, so a warning failing to appear immediately is not evidence of a fault.
This is a different control from an app-time allowance. Our family Screen Time guide covers the broader set of limits. Screen Distance responds to how close the screen is held, rather than granting or removing a daily allocation of app minutes.
Enable it in Settings
- Open Settings on the supported iPhone and scroll to Screen Time.
- Open Content & Privacy Restrictions, then choose Screen Distance. This is the route in Apple’s September 14, 2026 support instructions.
- Turn Screen Distance on. Enter the Screen Time passcode if asked.
- Return to the setting and confirm that the switch remains on.
If the control is missing, check both the TrueDepth requirement and the installed software version before treating it as a broken switch. If Settings requests a Screen Time passcode, use the authorised passcode; completing a software update does not remove that requirement.
Understand the interruption
When the distance warning appears, it covers the screen and prevents continued use until the viewing position changes. Move the iPhone back beyond 12 inches, wait for the screen to permit continuation, then tap Continue.
The expected result is a return to the previous activity with Screen Distance still enabled. Clearing that particular warning and disabling the setting are separate actions. There is no need to change the control simply because it did the job of interrupting close viewing.
Family settings can change after updates
Apple says Screen Distance is enabled by default for children under 13 in a Family Sharing group, with the age threshold varying by location. It recommends updating all devices in the group before changing settings so those settings can sync.
The company also says a child’s device update turns Screen Distance back on across their devices. If the switch appears to have changed after an update, review the family setup and software history before assuming a random reset.
Check the switch after setup and use the move-back-and-Continue sequence when an alert appears. Those two observations tell you what is configured and how to resume; neither requires inventing an exact alert timer that Apple has not published.
