Turn Call Barring On or Off
If your Samsung phone keeps rejecting calls while roaming or blocks all outgoing calls without an obvious reason, Call barring is likely active in the background. This network-level restriction can lock out specific call types entirely, and changing it requires a network password from your carrier rather than your screen lock. Voice calls and video calls are controlled separately, which often causes confusion when only one type is affected.
Change SIM Card Name
If your phone only shows SIM 1 and SIM 2, it is easy to grab the wrong line when you place a call or send a text on a dual-SIM phone. Samsung lets you replace these generic labels with a name you actually recognize, but the option sits inside the SIM card manager rather than the general network settings. Without renaming, call logs, message previews, and quick settings keep showing the default slot number instead of a clear label.
Change Edge Panel Position
By default, the Edge panel and its handle sit on the right edge of your Samsung screen. If that spot gets in the way of your grip or another gesture, you can swap the handle to the left edge and slide it up or down instead of living with the factory position.
Turn Do Not Disturb On/Off
When Do Not Disturb silences every call and notification on your Samsung phone, a call from your parents can end up muted right along with spam. Do Not Disturb runs either as a manual toggle or on a fixed schedule, and it treats every contact the same until you define exceptions. Missing an urgent message or a wake-up alarm often traces back to this one setting being active without you noticing.
Add or Remove Edge Panels
The Edge panel on your Samsung phone comes with a handful of panels active out of the box, but not every panel you might want is enabled - and you might be stuck with ones you never touch, like the calendar or direct dial panel. Extra panels, including a calculator panel, are available for free through the Galaxy Store but stay invisible until you select them in the panel list. Swiping in from the edge and seeing the wrong panels, or too few of them, usually just means the panel selection needs an update.
Show Battery Usage Stats
If your Samsung phone drains faster than expected, it is hard to tell which app or setting is responsible without a breakdown. Samsung's battery usage screen logs consumption hour by hour for up to seven days and marks exactly when the phone was recharged. That level of detail helps you spot whether an app, a screen-on session, or a background process is pulling the most power.
Turn Dark Mode On or Off in Samsung Internet
If Samsung Internet still opens in a bright white layout even though your phone runs a dark theme, the browser has its own separate dark mode toggle. Some users only find a system-wide switch and assume the browser has no dark option at all, while others get a dark browser frame but pages still render bright. The setting sits inside the browser app itself, not in the general display settings.
Allow Repeat Callers in Do Not Disturb
When Do Not Disturb is on, your Samsung phone silences every incoming call, even from someone trying to reach you urgently. The Repeat callers exception is meant to let a second call from the same number through within 15 minutes, but many users find it either missing or not working as expected. Knowing where this setting lives helps you decide when silence is too strict.
Change Keyboard Layout
Typing on the Samsung keyboard feels off when the layout does not match your language, or when you expected QWERTY but got QWERTZ. On German keyboards you can also switch between the standard layout and a compact 3x4 keyboard, and the wrong choice makes typing slower and more error-prone.
Allow or Block Display Over Other Apps
When a chat bubble or floating icon from an app like Facebook Messenger keeps covering your screen no matter what you open, that app has permission to draw over other apps. Some tools need this to work, like screen recorders or floating widgets, but many apps request it without a clear reason. If the overlay gets in the way or feels like a privacy risk, you can turn it off per app.
Remove a Folder from the Home Screen
A folder full of apps keeps taking up space on your home screen even after you have moved the apps out of it. On Samsung phones, folders behave like ordinary app icons, which confuses users looking for a delete option in a settings menu.
Turn On or Off SOS Emergency Messages
Pressing the side or power key three times fast can silently fire off an emergency text with your location to contacts you never meant to alert - or the feature might not trigger at all when you actually need it. This usually comes down to how 'Send SOS messages' is configured under Advanced features.
Keep Symbol Panel Open: Turn On or Off
When typing on the Samsung keyboard, a magnified preview of the character you tapped pops up over the key, no matter if alternate characters are active. If this popup gets in the way of fast typing, the 'Keep symbol panel open' option is the setting causing it.
Custom Notification Sound per App
On Samsung phones every app can technically get its own notification sound, but only if that app requests separate notification categories from the system. Apps that bundle everything into one generic channel keep the sound picker greyed out no matter what you try. That leaves you guessing whether a buzz is a message, a reaction, or a system alert.
Filter the Contact List by Account
If your Contacts app mixes Google, Samsung, and SIM entries into one long list, finding the right person during a call or while messaging gets tedious. Samsung lets you narrow the display to a single account or a custom selection instead of showing every contact source at once.
Search for a Word in a Message Conversation
Scrolling through a long text thread to find one phone number, address or name wastes time. Samsung's Messages app has a hidden search function inside each conversation that jumps straight to matching text. Matches get a white highlight and arrow controls let you step through every result without leaving the chat.
Remove App Shortcut from Home Screen
If you keep adding shortcuts for the same app to your Samsung Home screen, they pile up fast and there is no obvious delete button in sight. This happens because One UI treats every shortcut as its own tile, separate from the app icon in the App Overview. Many users end up dragging the wrong icon or accidentally uninstalling the app instead of just clearing the extra shortcut.
Hide or Unhide Gallery Albums
When apps like messaging, social media, or cloud backups create extra folders in your Gallery, the album list gets cluttered fast. These auto-generated albums often hold screenshots, downloads, or app-specific media you never meant to scroll through daily. Samsung Gallery lets you hide those albums from the overview without deleting any photos or videos inside them.
Turn Alternative Characters On or Off
If the Samsung Keyboard suddenly swaps letters for symbols like the question mark, plus sign, or euro symbol while you type, the Alternative characters function is active. This can slow you down when you need letters and numbers mixed together, for example in passwords or addresses. A setting inside the keyboard layout controls whether this swap happens automatically.
Turn On/Off Assistant Menu
If reaching the physical Home, Back or volume buttons with one hand feels awkward, the Assistant menu replaces them with a floating panel of on-screen shortcuts. The panel can be dragged to any spot on the display and holds up to 12 buttons, but on many phones it stays switched off or shows shortcuts you never use.
Resize the Samsung Keyboard
If the Samsung keyboard feels too wide for one-handed typing or the keys sit too close to the screen edges, the built-in size control usually fixes it. Keyboard height and width react to a hidden slider inside the keyboard settings, and the same menu lets you shift the whole layout toward the left or right edge of the display. Without adjusting it, typing with one thumb often means missed keys or accidental taps on the spacebar.
Turn Power Saving Mode On or Off
When your Samsung battery drains faster than usual, Power saving mode limits background data use and blocks location lookups for apps you are not actively using, while stretching what charge is left. Depending on the model, it can also turn off Always On Display and lower CPU speed, so screen behavior and app performance change until you switch the mode back off.
Change USB Connection Mode
After the first cable connection, Samsung remembers whatever USB purpose you picked and stops asking again. If that means your phone keeps loading as Charging only instead of File Transfer, moving photos or documents to a computer stops working until you switch the mode manually.
Filter Call History by Type
When your Samsung call log mixes missed, rejected, and outgoing calls together, finding one specific entry gets tedious fast. A built-in filter narrows the list down to just what you need, for example missed calls only or calls tied to one SIM. This works on any dual-SIM Samsung phone.
