What you need
Steps
Open the Galaxy Store on your Samsung phone and install Good Lock. If it is already on the phone, update it so the newest modules appear.
Open Good Lock, go to the Make up tab and install the Wonderland module. Tap Open when the download finishes.
In Wonderland, tap the plus button to start a new wallpaper. Pick a preset you like or begin from a blank canvas.
Add your portrait photo as the main layer, then add a background image behind it. Keep the subject in the centre of the frame.
Adjust the motion and depth sliders until the subject moves at a different speed to the background. Tap Save, then Set as lock screen.
Open Settings, then Wallpapers, and check the lock screen preview. If the photo is flat, tap the effect icon and turn on the depth effect toggle.
Go to Settings, then Lock screen, then Clock style. Choose a large style, pick a font and colour, and drag the clock to the top of the screen.
Still in Lock screen, open Always On Display and set it to show on tap or always. Pick the same wallpaper style so the look stays consistent.
Lock and the phone a few times to check the parallax, the clock size and the battery drain. Fine tune the Wonderland sliders if the effect feels too strong.
Tips and common mistakes
Depth effect works best on a portrait photo with a plain background and one clear subject.
If the depth toggle is missing, the wallpaper is probably too busy or the photo has no clear edge.
Good Lock modules are not available in every country, so check the Galaxy Store before downloading.
Very strong motion effects use more battery, so keep the sliders low if you need the phone to last all day.
Questions
Does a 3D lock screen drain the battery?
A little. The parallax effect wakes the screen sensors more often, and always on display adds to that. Keep motion low and turn off always on display if you need longer battery life.
Why is the depth effect not showing on my wallpaper?
The phone needs a subject it can separate from the background. Use a portrait photo with a clean backdrop, then turn the depth toggle on again in the wallpaper preview.
Is Good Lock free?
Yes, Good Lock and its modules are free from the Samsung Galaxy Store. You do need a Samsung account to download them.
