Reset App Preferences
If a link keeps opening in the wrong app, notifications stay silent, or a permission you never touched suddenly blocks a feature, one of your apps might have leftover setting changes piling up. Instead of checking every app individually, Samsung lets you roll all app preferences back to default in one step. This does not remove any app data, so accounts, files, and photos stay untouched.
Change Default Apps
If tapping a link always opens the wrong browser, or a newly installed messaging app never launches automatically, a leftover default app assignment is still active. Samsung keeps separate default apps for actions like opening links, sending texts or making calls, and a fresh install does not take over automatically. Until you reassign it, the old app keeps handling those actions.
Set App Timers
If one app on your phone keeps eating more of your day than planned, Samsung's App Timer can shut it down automatically once the daily budget runs out. The app closes itself and stays locked until midnight, then resets. Apps inside Secure Folder or dual-app clones are not affected by this limit at all.
Schedule Update Installation
Not every firmware update on your Samsung phone has to go in right away. Installing it in the middle of the day means the restart interrupts whatever you're doing. Samsung lets you pick a time within the next 24 hours so the install and restart happen automatically when you're not using the phone.
Change Home Screen Wallpaper
If your home screen still shows the old background after picking a new photo, Samsung One UI likely applied the change to the lock screen instead. The Wallpaper menu treats the start screen and lock screen as separate targets, so choosing the wrong one is the most common reason nothing visibly changes. This applies to both the built-in wallpaper packs and photos from your own gallery.
Add Apps to a Home Screen Folder
Once a folder sits on your Home Screen, dragging in one app at a time gets tedious fast. If you need to move several apps into the same folder, dragging each one individually wastes time and often fails when your fingers overlap icons. Samsung includes a faster method through the folder edit menu that handles multiple apps in a single pass.
Add New Apps to the Home Screen Automatically
After installing a new app, you check your Home screen and find nothing there. The app only shows up in the App Overview, which means an extra step every time you want to use it. This happens because the automatic Home screen placement option is turned off by default on Samsung devices.
Manage Full Screen App Display
When an app stretches oddly across the screen or crops content at the top and bottom, Samsung's full screen scaling is usually the reason. You cannot switch off full screen display system-wide, since it is tied to the display aspect ratio itself. What you can do is tell individual apps to render in the older, non-stretched format instead. This mainly affects apps that were never updated for taller Samsung displays and end up with distorted buttons or misplaced UI elements.
Turn Automatic App Updates On or Off
When apps update themselves in the background without asking, mobile data can disappear fast and storage fills up overnight. On Samsung phones this behavior comes from a Play Store setting, not a system-wide toggle, so it is easy to miss if you are looking in the wrong menu. If you want full control over when apps get new versions, this setting needs to be changed directly inside the Play Store app.
Select Apps for Brief Pop-up Notifications
When brief pop-up notifications fire for every app, alerts you do not care about keep interrupting the screen while you work on your phone. Samsung lets you pick individual apps for this pop-up feature, but the setting sits deep inside the notification menu and is easy to miss. Skip it, and apps you actually want pop-ups from might stay switched off while noisy ones keep interrupting you.
Install Print Service Plugin
If your printer does not show up when you try to print from your Samsung phone, the built-in print service most likely does not cover your printer model. Samsung ships with a standard print service that works with popular brands, but many manufacturers require their own plugin to print files correctly. Without that plugin, print jobs either fail or the printer never appears as an option.
Clear App Data (Reset an App)
If an app keeps glitching, shows outdated information, or you want to sign out completely without uninstalling it, clearing its stored data usually fixes this. This removes login details, cached files, and any saved content like messages or documents, putting the app back to its state right after installation. Clearing app data is different from just clearing the cache and cannot be undone.
Manage Special App Access Permissions
An app that keeps closing in the background or a security tool that won't uninstall usually points to a special access permission, not a basic one. Samsung handles settings like battery optimization or device admin rights per app, separate from the standard permissions for storage or contacts. These special accesses sit in their own menu and often get overlooked when troubleshooting.
