On iPhone 18 Pro, the Now Playing panel and bottom Lock Screen controls can use different material opacity and foreground colors for the same wallpaper and settings. The final appearance depends on the preceding wallpaper-editing sequence.
Environment
- Device: iPhone 18 Pro
- iOS: 27.2 beta (
24B5084k) - Liquid Glass: Clear / most transparent setting
- Wallpaper: Built-in iPhone 18 Pro wallpaper collection
- Variants tested: Silver and Black within the same saved wallpaper configuration

Two observed appearance states
For clarity, I use the following labels:
- Higher-opacity state (
S_s): The Now Playing panel and bottom buttons have a light or gray, relatively solid fill with dark foreground icons. - Translucent state (
S_t): The same elements are more transparent and use light foreground icons. In Sleep mode, they darken and blend into the background more naturally.
No Liquid Glass setting is changed during the following sequence.
Shortest reproduction sequence
1. Change Silver to Black
Start with the Silver variant displaying the higher-opacity state (Silver S_s).
Open the Lock Screen wallpaper carousel, tap Customize, change Silver to Black within the same iPhone 18 Pro wallpaper configuration, tap Done, and exit the carousel.
Observed result: Black retains the higher-opacity state (Black S_s).
2. Save Black without changing it
Reopen the same Black wallpaper in Customize, make no changes, tap Done, and exit.
Observed result: Black changes to the translucent state (Black S_t).
3. Change Black back to Silver
Reopen Customize, change Black back to Silver, tap Done, and exit.
Observed result: Silver retains the translucent state (Silver S_t).
4. Save Silver without changing it
Reopen the same Silver wallpaper in Customize, make no changes, tap Done, and exit.
Observed result: Silver changes back to the higher-opacity state (Silver S_s).
The complete sequence is therefore:
Silver S_s → Black S_s → Black S_t → Silver S_t → Silver S_s
The two actual appearance changes occur after reopening Customize and saving without changing the selected wallpaper.
Actual result
When switching between Silver and Black inside the same saved wallpaper configuration, the existing material state can be preserved even though the new wallpaper has a different brightness.
Reopening the configuration and saving it without making a change can then alter:
- Now Playing panel opacity
- Notification material appearance
- Bottom shortcut-button opacity
- Foreground or icon colors
As a result, the exact same Silver or Black wallpaper can appear in either state solely because of the preceding editing history.
Expected result
The material opacity and foreground colors should be determined consistently from the currently selected wallpaper and the Liquid Glass setting.
Switching between Silver and Black should update the appearance immediately if different treatments are intended for them. Saving an unchanged wallpaper should not alter the Lock Screen appearance.
Sleep mode impact
The issue is especially noticeable in Sleep mode. In the higher-opacity state, the Now Playing panel and bottom buttons remain conspicuous gray elements against the darkened Lock Screen. In the translucent state, the same controls darken and integrate with the background.
Supporting evidence
The corresponding Feedback Assistant report, FB24866793, includes:
- A screen recording of the complete sequence in normal mode
- A screen recording of the same sequence in Sleep mode
- A detailed PDF report containing screenshots, terminology, additional observations, and reproduction paths
Both recordings show the following sequence:
Silver S_s → Black S_s → Black S_t → Silver S_t → Silver S_s
The recordings and PDF cannot be attached directly to this Developer Forums post, but they are available to Apple through the Feedback Assistant report.
Request for confirmation
Could anyone else with an iPhone 18 Pro test this sequence on the same iOS build?
If you can reproduce it, please consider filing a separate Feedback Assistant report and referencing FB24866793.
