B) One‑tap from the Dejavu app
iOS (via Shortcuts)
First‑time setup
-
In the Dejavu app, open a wallpaper Detail page → tap Set as Wallpaper.
-
You’ll jump to Apple Shortcuts to add “Dejavu — Set Wallpaper”. Tap Add Shortcut.
-
If iOS asks to allow external shortcuts: Settings › Shortcuts › Allow Untrusted Shortcuts → ON, then return and Add.
-
On first run, Shortcuts may ask for permissions (Photos access, etc.). Tap Allow / Always Allow.
Use it
-
Back in Dejavu, tap Set Now on the wallpaper.
-
The Shortcut runs and lets you apply to Lock, Home, or Both in one tap (follow on‑screen prompts).
-
You can open the Shortcut to change defaults (e.g., always set to Lock Screen).
Note: iOS capabilities vary by version. If direct setting isn’t available on your device, the Shortcut will fast‑forward you to the system wallpaper screen with the image pre‑selected.

-
In the Dejavu app, open a wallpaper Detail page.
-
Tap Set as Wallpaper (or Set).
-
Choose Home, Lock, or Both → crop/confirm.

If prompted, allow Photos/Media permission so the app can pass the image to the system.
Troubleshooting
