Samsung Home Up One UI 9 home screen fix: who needs it

Samsung has pushed out Home Up version 18.0.00.38, a Good Lock update fixing two home screen glitches on Galaxy devices running One UI 9: DIY Home layouts that changed on their own and Stack Widgets that displayed incorrectly, Android Headlines reported yesterday. If you use Home Up's DIY Home Screen feature on a One UI 9 device, this is the version number to look for inside Good Lock.

The fix is narrow by design. It touches only the DIY Home Screen module inside Home Up, not every Galaxy owner's stock launcher. It's also the second Home Up patch in about ten weeks aimed at this general cluster of layout problems, following an August release that targeted a similar bug tied to foldable devices. That pattern says as much about how stubborn this corner of One UI 9 has been as the fix itself.

What the Home Up 18.0.00.38 update fixes on One UI 9

Android Headlines reports that version 18.0.00.38 corrects an error where DIY Home layouts changed unexpectedly, plus a separate issue causing Stack Widgets to display abnormally. DIY Home Screen is an option inside Home Up that allows detailed control over icon and widget placement, while Stack Widgets group multiple widgets, like Calendar and Weather, into a single stacked block on the home screen, per the same report.

Both fixes come from a single changelog description relayed by that outlet, not from a Samsung changelog GadgetHacks has independently reviewed. Treat the fix language as reported rather than confirmed through hands-on testing. What the update does establish is scope: this is a DIY Home patch tied to Home Up, not evidence that stock One UI home screens are rearranging themselves for people who never open the DIY Home feature.

One UI 9 is Samsung's current software layer, built on Android 17, according to Android Headlines. That's worth noting because this patch doesn't extend to devices still running older One UI versions.

How to install the Good Lock Home Up update

Installing it is simple enough: Android Headlines notes that Home Up updates run through Good Lock itself, so open Good Lock, find Home Up among the installed modules, and apply the available update. The report doesn't say whether the install restores a custom layout automatically, so screenshot your current DIY Home setup first. It costs nothing and gives you something to rebuild from if anything shifts during the update.

Availability for 18.0.00.38 specifically isn't detailed in that reporting. For context, Samsung's prior layout fix in August rolled out gradually by device and region, and at that point stable One UI 9 was limited to the newest Fold series while the Galaxy S26 line remained in beta, according to SamMobile. If you're on a Galaxy S26 device, confirm which One UI version you're actually running before assuming this update applies to you.

Why foldable Galaxy owners have felt this bug the most

Foldable owners appear to have driven much of the pressure behind these fixes. Before the August update, Galaxy owners on foldable devices had spent a couple of months reporting that apps were relocating on their own inside the DIY Home layout, SamMobile reported. Samsung framed that August release, version 18.0.00.32, as a fix for a DIY Home "layout location error" tied directly to those complaints.

October's update doesn't single out foldables the way the August fix did. Android Headlines' description of 18.0.00.38 covers Galaxy devices on One UI 9 broadly, without naming a specific device class. Whether foldable owners are still generating most of the reports behind this release isn't addressed in that coverage, so there's no confirmation either way, just a pattern worth watching.

A pattern of patches: two fixes in ten weeks

Version 18.0.00.32 landed in August, targeting the DIY Home layout location error after foldable owners had spent a couple of months reporting the app-shifting problem, per SamMobile. Version 18.0.00.38 followed about ten weeks later, addressing DIY layout changes again, this time alongside the new Stack Widget issue. Whether October's fix is a continuation of August's bug, a regression, or an unrelated defect with similar symptoms isn't something the current reporting settles.

SamMobile also noted in August that Samsung was preparing a broader update to the entire Good Lock suite to smooth out the One UI 9 transition, which suggests Home Up's rough stretch is part of a wider software shift rather than an isolated glitch. Two confirmed patches touching overlapping territory within ten weeks is reason enough to treat DIY Home as a feature worth updating promptly, not one that's fully settled just because a changelog says "fixed."

What to do now

If you use Home Up's DIY Home Screen feature on a Galaxy device running One UI 9, open Good Lock, check the Home Up version, and update if you're below 18.0.00.38. Screenshot your layout first, and keep an eye out for any icons or widgets that need manual repositioning once the update finishes installing.

If you're not using DIY Home and you're still seeing icons or widgets drift, this update isn't built for your situation. If your Samsung home screen layout keeps changing on an older One UI version, nothing in this patch's documented scope suggests it was built to fix that too, so treat it as a separate problem and work through standard launcher troubleshooting rather than waiting on a Home Up update to solve it.
