Turn On/Off Palm Swipe to Capture

If swiping the edge of your hand across the screen does not trigger a screenshot, or if it fires by accident while you grip the phone, the Palm swipe to capture gesture is set the wrong way. This motion feature sits in the gesture settings and can be missed easily since it is off by default on some devices.

Network & Connectivity

Show or Hide Date and Location in Gallery Photos

If the photo details in the Gallery only show file size and resolution, but never a place name, geotagging was probably switched off when the shot was taken. The date and location overlay only works retroactively for pictures that already carry that metadata.

Open
Calls & Messages2

Turn Call Waiting On or Off

If a knocking tone interrupts your calls out of nowhere, or you never notice a second caller trying to reach you, Call waiting is probably set the way you don't want. This Samsung feature decides whether an incoming call during an active conversation gets signaled to you or blocked outright. Getting the setting wrong means either missed calls or unwanted interruptions mid-conversation.

Open
System & Settings2

Set Time Manually

If your Samsung phone shows the wrong time even though it pulls it from the mobile network, a weak signal or a carrier sync issue is usually behind it. This throws off scheduled alarms, calendar entries and app timestamps until the automatic date and time source is disabled. Once that toggle is off, you can enter the correct time yourself.

Open
Photo, Video & Media2

Save a Web Page as PDF

Recipes, route planners or a step-by-step guide often disappear once you close the tab, lose signal or the page gets updated. Bookmarking only keeps a link, and the offline saving option in the Samsung Internet browser does not always preserve the layout. Exporting the page as a PDF keeps the text, images and formatting stored directly on your phone.

Open
Battery & Power2

Turn Adaptive Power Saving On or Off

If apps you rarely open stop sending notifications or refuse to sync in the background, Adaptive power saving is likely throttling them without asking you first. This automation tracks how often you use each app and quietly cuts background access to the ones it decides you barely need. Turning it off hands manual control back to you for every app's power behavior.

Open
Apps & Installation2

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.

Turn Autofill Service On or Off

If your phone keeps filling in the wrong username, an old address, or a password you no longer use, the Autofill service is likely set to a provider you did not choose. On Samsung phones this function can pull data from Google, from Samsung Pass, or be switched off completely, and mixing providers often causes those wrong entries or missing suggestions in login and shipping forms.

Open
Security & Privacy2

Manage App Permissions via Permission Manager

When you install a new app on your Samsung phone, it starts with no access to your camera, microphone, storage or location. Only once you open the app or trigger a specific feature for the first time does a permission prompt appear on screen. If you tapped Deny by accident or want to review which apps can read your contacts, gallery or location, you need Permission manager to check and change each permission individually.

Open
Apps & Installation2

Restore Default App Icons

Once you've applied a custom icon pack on your Samsung phone, there's no toggle in the app settings or launcher menu to bring icons back to their original look. The only place that reset lives is inside the Themes app, which most people never open again after installing a theme or icon set.

Open
Calls & Messages2

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.

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.

Open
Network & Connectivity2

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.

Open
Notifications & Focus2

Turn On/Off Bedtime Mode

If your Samsung phone suddenly switches to grayscale and notifications stop coming through at night, Bedtime mode is likely active. Held-back alerts only appear once the scheduled period ends, which can make it look like your phone stopped receiving messages entirely. This differs from Do Not Disturb, since Bedtime mode also dims the display and can run on a fixed schedule.

Open
Calls & Messages2

Show or Hide Public Holidays in Calendar

If public holidays keep showing up in your Samsung Calendar even though you never added them, they are pulled in automatically from a signed-in Google Account. Which country's holidays appear depends on the region or language set in your system preferences, not on the calendar app itself. Turning them off means adjusting the display settings for that specific account, not deleting entries one by one.

Open
Security & Privacy2

Add Trusted Devices for Smart Lock

If your Samsung phone still asks for a PIN every time you get in the car or plug in your headphones, Smart Lock is not recognizing your Bluetooth accessory as trusted yet. Without a registered device, the phone falls back to full lock screen security even when it is clearly connected to something you use daily. Adding the right accessory as a trusted device lets the phone skip the lock screen automatically while that connection is active.

Open
Storage & Backup2

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.

Open
Language & Input2

Keyboard Touch and Hold Delay

If long-pressing a key on your Samsung keyboard keeps popping up accent marks or symbols by accident while you type normally, the touch and hold delay is set too short for your typing speed. The opposite problem also happens: if you have to hold a key noticeably long before the alternate character menu shows up, the delay feels too slow for quick access to accents and special signs. Samsung lets you shorten or lengthen this response time instead of living with either annoyance.

Open
Notifications & Focus2

Show or Hide Secure Folder Notification Content

When an app inside Secure Folder sends a notification, Samsung hides the actual content by default, both on the lock screen and in the notification panel. You only see that something arrived, not what it says, which gets confusing when you rely on message previews. This behavior comes from a separate privacy setting inside Secure Folder, independent of your normal notification content settings.

Open
Apps & Installation2

Allow or Restrict Background Activity of Apps

If your Samsung phone loses battery fast even when you barely touch certain apps, background activity is often the reason. Some apps keep syncing, refreshing content or checking location while you are not using them, which quietly drains the battery between charges. You can turn this off for individual apps without disabling their notifications completely.

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.

Open
Notifications & Focus2

Show or Hide Notifications on Always On Display

If your Always On Display keeps showing notification icons you would rather keep off the lock screen, that is the default Notifications behavior on Samsung phones. These icons only signal that a message arrived and never reveal sender or content, even when the setting stays on. Turning it off removes the icons from the always-on screen completely.

Ignore Repeated Touches: Turn On or Off

If a single tap on your Samsung device sometimes registers as two or three taps, or a light touch triggers extra input, the screen may be reacting to accidental double contact. The Ignore repeated touches feature controls how long the display waits before accepting another tap after the first one. Adjusting it helps if you have shaky hands, a cracked screen, or a case that causes phantom touches.

Open
Notifications & Focus2

Change Alarm Sound

If every alarm on your Samsung phone still plays the same default tone, you probably haven't discovered that each alarm can carry its own sound. Many users only ever adjust the general alarm tone and miss the option hidden inside a single alarm entry. This means the loudest, most jarring tone often wakes you every morning even when a gentler option is available.
