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.

Change Clock Style on Lock Screen

If the lock screen clock always shows the same digital format and you want a different layout, color or extra details like seconds and date, the option is buried inside the lock screen settings rather than the display menu. Some phones also show a grayed-out clock style option when Roaming Clock is active, which stops you from customizing anything until it's turned off.

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.

Apps & Installation2

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.

Open
System & Settings2

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.

Add a Fingerprint on Samsung

Trying to unlock your Samsung phone with your fingerprint but the option in Settings stays greyed out? Samsung always requires a backup PIN, password, or pattern before the Fingerprints menu becomes available. Without that secondary lock set first, you cannot enrol a new fingerprint at all.

Open
Language & Input2

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.

Open
Network & Connectivity2

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.

Calls & Messages2

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.

Open
Network & Connectivity2

Forget a Saved Wi-Fi Network

If your Samsung phone keeps trying to reconnect to a Wi-Fi network you no longer use, an old saved profile is still stored on the device. This forces constant background scanning for that network and can slow down how quickly your phone switches to a stronger signal nearby. Removing the outdated entry stops the automatic search for good.

Add Alarm Widget to Home Screen

Checking whether tomorrow's alarm is still active means opening the Clock app every time, even for a quick glance. Samsung's Alarm widget puts a single alarm directly on your Home screen, so you can switch it on or off and see the time without unlocking into the app. Each widget only tracks one alarm, so multiple alarms need one widget each.

Change the Default Homepage in Samsung Internet

Samsung Internet opens with Quick access by default, a screen full of shortcuts to sites like Google, eBay or Tchibo instead of the page you actually want to see. You can switch to a personalized start view, the most-visited sites list, or a fixed web address of your choice. The option sits inside the browser menu and is easy to overlook the first time you look for it.

Show or Hide Calendar Week Numbers

If your Samsung Calendar does not show which calendar week you are currently viewing, the week number display is probably switched off. Without it, planning around ISO week numbers for invoices, shifts, or project deadlines means counting weeks by hand. The option sits inside the calendar app itself, not in the general phone settings.

Add a New Contact

Typing a number straight into the dialer only leaves it in your call log, not in your address book. If you clear that history or set up a new phone, the number is gone for good. The Samsung Contacts app is the only place that permanently stores a name together with a phone number and any extra details you add.

Switch Between Open Tabs in Samsung Internet

With several tabs open in Samsung Internet, finding the right one again can take a few tries, especially once previews start looking alike. Some tabs also seem to reload from scratch every time you switch back to them. There is more than one way to jump between tabs, and one of them is a lot faster than tapping through the tab overview.

Edit and Reorder Edge Panel Contacts

If your Edge panel still shows outdated contacts or apps you never open, the panel content does not update on its own and needs manual editing. Positions also stay fixed until you rearrange them yourself, which often buries your most-used contacts at the bottom of the list.

Network & Connectivity2

Turn Data Roaming On or Off

When your Samsung phone connects to a foreign carrier network instead of your home network, mobile data stops working until Data roaming is switched on. That is fine while you stay close to home, but abroad it blocks emails, maps and apps from loading over the mobile network. Switching it on without checking your plan first can also lead to unexpected charges.

Camera Timer: Set Self-Timer for Photos and Videos

Selfies and group shots often turn out blurry or rushed when you tap the shutter yourself, since the phone locks focus at that exact moment. The Camera app has a built-in self-timer that adds a countdown before the shot fires, so you can put the phone down and get into position first. On Samsung devices you can choose a delay of 2, 5, or 10 seconds depending on how much time you need.

Customize Secure Folder Name and Icon

If your Secure Folder still carries its default label and icon, anyone glancing at your app list can spot exactly what it hides. Samsung lets you rename it and swap the icon for something less obvious, but the icon options are limited to presets and the initial letter of your chosen name. You cannot upload a custom image as the icon.
