And even that does not work! It has taken me most of a day to cajole copilot into producing the following instruction sheet that EXPLAINS where the problem lies: You CAN'T fix SOME of the lock screens. Why Apple can't tell us that up front is beyond me!
📱 iOS 26.2 — The Correct Guide to Fixing (and Saving) the Lock Screen Liquid Glass Clock Adjustment
🚨 START HERE — The #1 Thing Everyone Must Know
In iOS 26.2, some Lock Screen wallpaper types CANNOT save Liquid Glass adjustments.
If you’re using one of these, the slider will always reset:
❌ Dynamic & Regenerating Wallpapers
- Astronomy
- Weather
- Earth / Moon / Solar System
- Photo Shuffle (People mode)
- Certain Color Gradients
These wallpapers rebuild themselves every time you leave the Lock Screen, which overwrites your transparency setting.
If you’re using one of these, stop here — switch to a static wallpaper first.
✅ Wallpapers That Do Save the Liquid Glass Setting
These work correctly in iOS 26.2:
- ✔ Static Photo
- ✔ Solid Color
- ✔ Emoji
- ✔ Kaleidoscope
- ✔ Pride
- ✔ Collections
If you use one of these, the slider will finally stick.
🛠 How to Apply and Save the Liquid Glass Adjustment (iOS 26.2)
Once you’re using a supported wallpaper type:
1. Press and hold your Lock Screen
2. Tap “Customize”
3. Choose “Lock Screen”
4. Tap the clock
This opens the font & Liquid Glass controls.
5. Adjust the Liquid Glass / Transparency slider
Make the clock more solid or more glassy.
6. To save the change: tap the wallpaper thumbnail in the top-left corner
This is the new, hidden “save” action in 26.2.
7. Choose one of the prompts:
- Set as Wallpaper Pair
- Set as Lock Screen Only
This is the moment the setting is actually written to the wallpaper profile.
8. Exit the editor
Your adjustment will now persist.
🔍 If the slider still resets
You are definitely using a dynamic wallpaper type.
Switch to a static Photo and repeat the steps — it will work.
🎯 Why This Happens
iOS 26.2 moved Liquid Glass rendering into the wallpaper engine.
Dynamic wallpapers regenerate their layers every time you leave the Lock Screen, which wipes:
- clock transparency
- font weight
- blur
- color mapping
This is a design limitation, not user error.
