If you're using One UI 6 Beta (or even previous One UI versions), and you want your home screen folders to appear more compact/vertical, here's what you can try:
Open the folder on your home screen.
Tap the three-dot menu (⋮) in the top-right corner of the folder.
If available, choose "Edit folder" or "Folder settings."
Look for options like "Grid layout" or "Compact view." (Note: These options might vary depending on your version of One UI or if you're in the beta.)
Alternatively, try reducing the number :of apps: in the folder — One UI adjusts folder size dynamically based on how many items are in it.
Unfortunately, One UI doesn’t yet allow full custom control over folder dimensions like vertical-only stacking — but you can send feedback via Samsung Members app to suggest it 📬.
