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.
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.
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.
Turn Lock Screen Notifications On or Off
If notification icons keep showing up on your Samsung lock screen even though you want more privacy, or they suddenly stopped appearing at all, the Notifications setting under Lock screen controls that behavior. This single switch decides whether senders, message previews, or just small icons appear before you unlock the phone. Getting it wrong can mean missing calls or messages, or exposing content you would rather keep hidden.
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.
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.
Allow Calls in Do Not Disturb
When Do Not Disturb is active on your Samsung phone, every incoming call gets silenced by default, even from people saved in your contacts. This happens because the Calls, messages and conversations settings inside Do Not Disturb treat phone calls like any other notification unless you tell it otherwise. You can choose whether all calls, only contacts, only favorites, or none get through.
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.
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.
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.
Smart Anti-Tracking: Turn On or Off
Closing Secret mode does not stop every site from tracking you across sessions. Cookies and browsing traces from the regular Internet app can still build a profile of you, even after you clear history manually. Smart anti-tracking works independently of Secret mode and can clean this up automatically.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Add an Account to Calendar
If your appointments, birthdays or tasks from Google or Exchange are missing in the Calendar app, the account simply has not been linked yet. Samsung Calendar only shows data that is stored on your phone or connected through a synced account, so an unlinked account leaves whole calendars empty.
Schedule Dark Mode
If Dark Mode stays on well past sunrise or never switches off before you go to bed, the automatic schedule on your Samsung phone probably is not set up yet. Samsung lets you tie Dark Mode to sunset and sunrise or to a fixed time you choose, but this option sits switched off by default, so most people end up toggling the display mode by hand every day.
