Notifications & Focus

Show or Hide Notification Icons in Status Bar

When several apps send alerts at the same time, the Samsung status bar only keeps the three newest notification icons visible and quietly drops the rest. That makes it easy to overlook a message or reminder that landed earlier in the day. One UI actually offers three display modes for this row, but most people never open the setting that controls them.

Open
Storage & Backup2

Restore Backup from Samsung Cloud

After a factory reset or on a new Samsung phone, photos, contacts, and app data can be missing even though a backup exists in Samsung Cloud. This usually happens because the restore step was skipped during setup or the wrong backup was selected. The right backup needs to be picked manually before missing apps and files come back.

Security & Privacy2

Rename a Fingerprint

When you add several fingerprints on your Samsung phone, they all get generic labels like Fingerprint 1 or Fingerprint 2. If more than one person unlocks the same device, it gets confusing to tell whose print is stored where.

Open
Language & Input2

Change System Language

If your Samsung phone shows the wrong language after setup, or you simply want to switch to a different one, you do not need to reset the device. The system language can be changed at any time from the settings, and Android supports almost every major language.

Add an Alternative Face Look

Face unlock on Samsung phones can fail the moment your look changes, whether that means a new beard, glasses, a hat, or heavy makeup. One stored face profile often is not enough to cover these day-to-day differences. Samsung lets you register a second face profile so the system recognizes you under different conditions.

Open
Display & Home Screen2

Show Always On Display Always or on a Schedule

When Always On Display stays dark overnight or drains the battery non-stop, the culprit is usually the display mode hidden in the lock screen menu, not a hardware issue. Samsung lets you keep the clock and notifications on permanently or restrict them to set hours, and picking the wrong option either wastes battery or leaves you missing glances at your screen.

Open
Battery & Power2

Turn Maximum Power Saving Mode On or Off

When your Samsung phone suddenly runs painfully slow, background apps stop updating, and the Always On Display disappears, Maximum power saving is likely active. This mode cuts CPU speed to roughly 70 percent, blocks most background data, and only allows a limited number of apps to run. If you turned it on for an emergency and now need full performance back, or you want to switch it on before a long day away from a charger, you need the correct toggle in Battery settings.

Open
Storage & Backup2

Change Google Backup Account

If Samsung keeps backing up your data to the wrong Google Account, your photos, contacts and app settings end up in a profile you barely use. This usually happens when a second Google Account gets added to the phone after the first backup was already set up. Samsung sticks with the account chosen during initial setup until you switch it manually in the backup settings.

Close All Tabs in Samsung Internet

Too many open tabs in Samsung Internet slow the browser down and make it hard to find the page you actually need. Scrolling through dozens of thumbnails just to spot one tab wastes time and drains memory. Closing unused tabs regularly keeps the browser fast and responsive.

Open
Notifications & Focus2

Turn Keyboard Sounds On or Off

Every tap on the Samsung keyboard triggers a click sound that can get annoying, especially in quiet rooms or during calls. This tone runs independently from your ringtone, notification and media volume, so lowering those won't silence it. Two separate settings areas manage the keypad tone, and mixing them up is the usual reason one toggle does not seem to work.

Photo, Video & Media

Enable or Disable Quick Launch Camera

If a double press of the power button keeps opening your camera at the wrong moment, or you want that shortcut back after it stopped working, the Quick launch camera option is behind it. This function reacts to the side key whether the screen is on or off, and it ships active on most Samsung phones. A few taps let you turn it off or bring it back.

Open
Notifications & Focus2

Change System Sound Volume

If the sound for taking a screenshot or capturing a photo suddenly cannot be turned off on its own anymore, Samsung has likely bundled it into a shared system sound category. This means several alert tones now share one volume slider instead of separate toggles. Adjusting the level for this group affects every sound tied to it at once, not just one action.

Open
Notifications & Focus2

Change Ringtone for Calls

If every call on your Samsung phone still uses the same generic ringtone, the setting is hiding under sound options rather than notifications. On dual-SIM phones this gets more confusing, since each SIM line can carry its own separate ringtone. Custom tracks also will not show up in the ringtone list until they are copied onto the phone storage first.

Open
Photo, Video & Media2

Disable Autoplay Videos in Samsung Internet

Videos embedded in web pages start playing the moment a site loads in Samsung Internet, even over mobile data. That eats into your data plan and drains the battery before you have tapped anything on the page.

Change Edge Lighting Effects and Colors

By default, Edge lighting shows new notifications with a blue spotlight effect no matter which app sends them. That makes it hard to tell notifications apart without unlocking the screen. Samsung One UI offers several alternative effects and a full color picker to fix that.

Open
Calls & Messages2

Change Contact Name Format

If your contacts list shows names as First Name, Last Name and you would rather see Last Name, First Name, the display setting inside the Contacts app controls that order. This has nothing to do with how a contact was originally saved, so switching the format does not touch any contact data. The change only affects how names appear across Calls and Messages, not the underlying entries or numbers.

Open
Display & Home Screen2

Adjust Display Brightness

If your Samsung screen stays too dim or too bright no matter the lighting, the brightness slider might be locked to Adaptive brightness instead of manual control. This drains the battery faster and makes reading outdoors or at night harder than it needs to be. Switching to manual brightness gives you direct control over how much power the display uses.

Storage & Backup2

Download New Font Styles

Stuck with the same handful of system fonts on your Galaxy phone? Samsung keeps its full font library inside the Galaxy Store, separate from the regular font size and style menu. Free and paid styles are easy to miss if you do not know where Samsung tucks this option.

Open
Notifications & Focus2

Change Notification Sound

Notification tones on Samsung phones stay stuck on the default chime even when you have already changed your ringtone. Dual SIM devices let you assign a separate sound to each SIM card, but the tone list only offers standard, built-in options. There is no way to import a custom notification sound directly from this menu.

Open
Language & Input2

Set Default Keyboard

Installed a new keyboard app but your Galaxy phone still opens Samsung Keyboard for typing? That happens because a freshly installed keyboard is not automatically allowed to become the default input method. It first has to be switched on in the keyboard manager before the system even offers it as an option.

Open
Photo, Video & Media2

Restore Deleted Photos from Gallery Trash

A photo or video you thought was gone might still be recoverable on your Samsung phone. The Gallery app keeps deleted files in a hidden Trash folder, but only for a limited time before they are wiped for good. If the recycle bin was switched off or the file is older than the retention window, recovery is no longer possible.

Open
Network & Connectivity2

Pair a Bluetooth Device

If your Samsung phone will not connect to a speaker, headset, or car radio, the two devices are simply not paired yet. Phones and speakers usually just need to confirm the connection on screen, but many car radios ask for a numeric code to be typed in on the Samsung device. Missing that step is the most common reason Bluetooth audio never starts.

Open
Apps & Installation2

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.

Edge Lighting Display Timing

Edge lighting fires for every notification, whether you are actively looking at the screen or the phone is locked in your pocket. If the glow feels excessive or you barely notice it, the timing setting decides whether it shows during active use, only when the display is off, or in both cases.
