Samsung Lock Screen Generator

Build a Galaxy lock screen over your own wallpaper or a built-in gradient. Choose the stacked or single-line clock, show notifications the way One UI does — as app icons, or expanded into cards — and export at the size the real phone writes.

The lock screen is where the platforms diverge most

Home screens and app screens converge; lock screens don't. Four differences separate a Galaxy lock screen from an iPhone one, and all four are visible without looking twice:

Notifications collapse to app icons. One UI shows a row of circles and expands to cards on tap. iOS stacks frosted cards from the bottom and has no compact state.
The clock face is a choice, and the stacked two-row face has no iOS counterpart at all.
The shortcuts are Phone and Camera. iOS gives you flashlight and camera.
The date sits under the clock. iOS sets it above.

If you need the Apple version instead, the iPhone Lock Screen Generator is the same idea built on the iOS layout.

Export sizes

Galaxy S24 / S25 — exports at 1080×2340px (Galaxy S-series and most A-series at 1080×2340)
Galaxy Ultra (QHD+) — exports at 1440×3120px (Galaxy S Ultra and Plus switched to QHD+, at 1440×3120)
Galaxy Z Flip — exports at 1080×2640px (Z Flip main display at 1080×2640 — a taller 22:9)

Questions

Why do the notifications show as circles instead of cards?

Because that is One UI's default. Samsung collapses lock screen notifications into a row of app icons and expands them into cards only when you tap one. iOS has no compact state at all, so this is the single most Samsung-looking thing on the screen. The tool does both — switch between App icons and Expanded.

What is the stacked clock?

A One UI clock face that sets the hour on one line and the minutes on the line below it. There is no iOS equivalent, and it is the default on a lot of Galaxy phones. The tool splits whatever you type at the colon, so it works for 9:41 and 09:41 alike, and falls back to a single line if there is nothing to split.

Why is the left shortcut a phone rather than a flashlight?

Samsung puts the dialler there. Apple puts the flashlight. It is a small thing, and it is also the sort of detail that makes a mockup read as the wrong platform to anyone who owns the phone.

What resolution does it export?

Whatever the selected Galaxy actually writes — 1080×2340 for the S24 and S25 preset, 1440×3120 for QHD+, and 1080×2640 for the Z Flip.

Does my wallpaper get uploaded anywhere?

No. The tool runs entirely in your browser and there is no server behind it to upload to. Your image is read locally, rendered locally, and gone when you close the tab.

What would make this tool better? A device that's missing, a detail that looks wrong, an option you went looking for and didn't find — all of it is useful. Send a note.
