On the iPhone 14 Pro, Always-On Display (AoD) is the feature customers notice missing first after a screen repair. The lock screen goes fully black between notifications and they assume something broke. Sometimes nothing is broken - and sometimes the panel you installed simply cannot do AoD. This walkthrough tells you which situation you are in.
Step 1: Confirm the Feature Should Be On
First eliminate the free explanations:
- Settings, Display and Brightness, Always On Display - confirm the toggle exists and is on. If the toggle is missing entirely, jump to Step 3.
- Low Power Mode disables AoD - turn it off and lock the phone.
- Focus modes with Always On dimmed, and the raised-to-wake interactions, can hide AoD behaviorally. Test with a fresh lock and a flat surface.
Only after these pass should you open Settings versus the phone.
Step 2: Understand Why the Toggle Might Be Gone
iOS only shows the AoD toggle when it believes the installed panel supports the feature. Two things make iOS change its mind after a repair:
| Situation | What you see | Meaning |
|---|---|---|
| Toggle present, AoD absent | Setting exists, screen stays black | Settings or a marginal panel - continue Step 3 |
| Toggle disappeared after swap | No Always On option in Settings | iOS reads the panel as non-AoD capable |
| Toggle disappeared plus Unknown Part warning | Both at once | Aftermarket panel without paired display data |
Step 3: The Panel Capability Question
AoD requires the display driver to sustain a low-power 1Hz refresh path. Original pulled panels support it. Many aftermarket assemblies - even visually excellent ones - ship drivers that do not, and iOS then hides the feature. This is not a defect you can update away; it is silicon capability.
For shops, the practical guidance:
- If the customer's priority is AoD, source original pulled or AoD-verified assemblies from our screen collections - verify before you promise, on a test device if possible.
- If the customer accepts losing AoD, a quality standard assembly is often the better price-performance choice - set that expectation at intake, in writing.
- Document the trade-off on the work order. The most common AoD comeback is not a fault - it is an unmet expectation.
Step 4: Sanity Checks Before Closing
After installing any 14 Pro assembly, verify ProMotion still switches (Settings reveals refresh behavior in developer options, or observe scrolling smoothness), auto-brightness responds, and True Tone state is discussed with the customer. A panel that passes all of those but lacks AoD is a functioning part - it is a purchasing decision, not a repair failure.
FAQ
Does the Unknown Part warning remove AoD? The warning itself does not, but the unpaired display data and the panel capability often arrive together.
Can a firmware or restore bring AoD back? If the panel is genuinely AoD-capable and the toggle vanished after an update glitch, a restore can. If the panel lacks 1Hz support, no.
Do battery or camera repairs affect AoD? No - AoD lives entirely in the display and its data pairing.
