Turn Location (GPS) On or Off
If navigation apps cannot find your position or refuse to load a route, Location access is often switched off on your Samsung phone. Weather widgets, Find My Mobile, and location-tagged photos rely on the same GPS toggle, so one setting affects several features at once. Turning it off saves battery but breaks any app that needs your real-time position.
Encrypt or Decrypt SD Card
If your Samsung phone gets lost or stolen, anyone can pull the SD card and read the photos or app data stored on it. Samsung lets you tie the card to your device with encryption so it becomes unreadable in any other phone or card reader. This only works reliably if you set a screen lock first, since the encryption is unlocked using your Pattern, PIN, or Password.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Delete a Contact Group
If a contact group on your Samsung phone has outlived its purpose, it stays listed in your Contacts app until you remove it manually. You can delete just the group label or wipe the group together with every stored member. One group, Emergency contacts, cannot be removed this way.
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.
Turn On/Off Auto HDR
Bright skies turn white and shadows go black in the same shot on your Samsung phone. That washed-out look usually means Auto HDR is switched off, so the camera cannot merge multiple exposures into one balanced photo. High-contrast scenes like backlit portraits or landscapes with strong sun suffer most from this.
Add a Wi-Fi Network Manually
If your router does not appear in the Wi-Fi list, it usually means the network is hidden and not broadcasting its name. In that case you have to add it by hand using the exact SSID and, if the network is secured, the correct password. A typo in either field is the most common reason the connection still fails afterward.
Back Up Data to Samsung Cloud
A phone that gets lost, stolen or bricked takes any local backup with it. If contacts, photos or app data only exist on the device itself, a factory reset or hardware failure wipes them for good. Backing them up to your Samsung account keeps a copy safe outside the phone.
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.
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.
Turn Charging Vibration On or Off
Your Samsung plays a short tone every time you plug in the charger, even when you would rather feel a quiet vibration instead. This behavior is tied to the System sound/vibration control settings, which decide whether charging triggers sound, vibration, or stays silent. Get this setting wrong and you either miss charging confirmations in loud environments or get startled by tones during meetings.
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.
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.
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.
