Add an Alternate Calendar
If dates on your Samsung calendar don't match the Lunar, Hijri, or Shamsi calendar you expected, the alternate calendar option is probably switched off. Samsung's Calendar app can show a second calendar system in smaller text next to the standard dates, but it stays hidden until you set it manually in Settings. This affects the Korean, Chinese, and Vietnamese Lunar calendars as well as Hijri and Shamsi dates.
High Contrast Keyboard: Turn On or Off
If the stock keyboard is hard to read in bright light or the keys feel too small, a low-contrast color scheme is usually the cause. Samsung Keyboard has a built-in 'High contrast keyboard' mode that swaps the color scheme and enlarges key size at the same time. Availability and exact designs vary slightly depending on the Samsung model you use.
Change Ringtone Volume
If your phone barely rings during incoming calls even though media volume is turned up, the volume keys are probably adjusting the wrong stream. On many Samsung phones, pressing the side buttons on the home screen changes media volume by default and leaves the actual ringer level untouched.
Turn Always On Display On or Off
On some Samsung phones the lock screen stays completely dark until you press the power button, even though you want the clock or notifications visible at a glance. On others, the screen glows constantly and you are trying to figure out why it never turns fully black. Both situations trace back to a single lock screen setting that controls whether the display stays partially lit.
Add Apps to a Home Screen Folder
Once a folder sits on your Home Screen, dragging in one app at a time gets tedious fast. If you need to move several apps into the same folder, dragging each one individually wastes time and often fails when your fingers overlap icons. Samsung includes a faster method through the folder edit menu that handles multiple apps in a single pass.
Open a New Tab in Samsung Internet
Trying to check a second website without losing the page you already have open? Samsung Internet handles this through tabs, and if you don't know where the option sits, you end up replacing your current page instead of adding a new one. This mainly affects people switching from other browsers where the tab icon looks different.
Delete a Saved Fingerprint
Old fingerprints stored on your Samsung phone stay active even after you stop using them, and every extra entry gives a spoofed or borrowed print another chance to unlock the device. If a family member's finger, a child's print, or an unreliable scan is still registered under Fingerprints, it can grant access you no longer want. Removing entries you do not need closes that gap without touching your other saved biometrics.
Edit a Saved Contact's Details
A contact's phone number or email often changes, but deleting the whole entry and creating a new one throws away the call history and message threads tied to that contact. Samsung's Contacts app lets you update individual fields directly, without breaking the link to existing calls and chats. Skipping this and adding a duplicate contact instead is the most common mistake here.
Add New Apps to the Home Screen Automatically
After installing a new app, you check your Home screen and find nothing there. The app only shows up in the App Overview, which means an extra step every time you want to use it. This happens because the automatic Home screen placement option is turned off by default on Samsung devices.
Turn the Flashlight On or Off
Looking for a flashlight app on your Samsung phone? You will not find one, because Samsung built the torch function directly into the quick settings panel instead of a separate app. If you cannot locate the toggle, the tile has usually been moved or removed from your quick settings.
Add Emergency Medical Info to Contacts
If first responders can't tell rescue workers about allergies, medications or blood type, critical seconds get lost during an emergency. Samsung phones let you store this medical information directly in your Contacts profile, but many users never find where to enter it. The data lives outside your regular contact card and stays visible even when the phone is locked.
Take Photos with a Tap on Screen
Holding your phone at arm's length for a selfie makes the shutter button hard to reach, especially with one hand. Samsung's camera offers a shooting method called Tap screen that turns the whole preview into a trigger area instead of relying on the small button. Without it switched on, you're stuck stretching your thumb across the screen every time.
Schedule Eye Comfort Shield (Blue Light Filter)
Manually turning Eye comfort shield on and off every evening gets old fast, especially when sunset times shift throughout the year. If the blue light filter only ever runs when you remember to tap it, you are missing the automatic scheduling option built into the display settings. A fixed start and end time or a sunset-to-sunrise rule keeps the warm tint active exactly when you need it.
Set a Custom Ringtone
Tired of the same handful of default tones on your Samsung phone? If a downloaded ringtone or your favorite song does not show up when you try to assign it, the sound picker usually just has not scanned that folder yet or the file sits in a format the phone does not recognize as a ringtone.
Quick Settings Button Grid Size
If your Samsung quick settings panel feels cramped or only shows a handful of toggles, the button grid is likely still stuck on the default size. Switching to a larger 5x3 layout fits up to 15 shortcuts at once, while 3x3 keeps each tile bigger and easier to tap.
Set Up a VPN Connection
Streaming services blocking your location, unsecured public Wi-Fi, or a company network that only accepts encrypted traffic - all of these push you toward a VPN. On Samsung phones the connection only routes through a VPN server once a valid profile has been created manually, since One UI does not ship with preset providers.
Turn Mobile Hotspot On or Off
If you need to share your Samsung phone's mobile data connection with a laptop, tablet, or another phone, Mobile Hotspot has to be switched on first. Without it, nearby devices cannot detect your phone as a Wi-Fi access point at all. Many people also struggle to find where this toggle sits once they need to turn it off again to save data or battery.
Mute a Conversation in Messages
When one contact keeps sending message after message, your phone keeps lighting up and buzzing even though you have no interest in leaving that chat entirely. Samsung Messages lets you silence a single conversation without blocking the sender or deleting the thread. The notification setting for that one chat works independently from your general Messages notifications, so muting a contact won't affect alerts from anyone else.
Lock Secure Folder Manually
If Secure Folder stays open after you close it, the automatic lock timer or restart-only setting is probably still active. That leaves private apps and files reachable until the timer runs out or the phone reboots. A manual lock option inside the folder closes it right away, without waiting for either condition.
Power Off a Samsung Device
On newer Samsung phones, holding the power button often opens Bixby instead of the shutdown menu, so the classic press-and-hold trick stops working. If your device does not react when you hold the side key, the button has likely been reassigned and you need another way to power down. This mix-up leaves many users stuck between a frozen screen and an assistant they never asked for.
Delete Single or Multiple Contacts
Deleted contacts sometimes come back or disappear for good, depending on your Samsung software version. On newer Android releases with One UI, removed contacts sit in a trash bin for 30 days before they are gone permanently, while older Android 9 devices delete contacts right away, even if they were saved to your Samsung or Google account.
Increase Touch Sensitivity for Screen Protectors
If your Samsung phone misses taps or feels sluggish after fitting a tempered-glass screen protector, the touchscreen is likely filtering out part of your input. Thicker protective films add a layer between your finger and the sensor, which throws off the standard touch calibration. A dedicated sensitivity setting compensates for this without forcing you to switch protectors.
Manage Full Screen App Display
When an app stretches oddly across the screen or crops content at the top and bottom, Samsung's full screen scaling is usually the reason. You cannot switch off full screen display system-wide, since it is tied to the display aspect ratio itself. What you can do is tell individual apps to render in the older, non-stretched format instead. This mainly affects apps that were never updated for taller Samsung displays and end up with distorted buttons or misplaced UI elements.
Move Apps to an SD Card
Samsung phones install every app to internal storage by default, and that fills up fast once photos, games and updates pile on. If your device has a memory card slot, moving apps off internal storage is often the quickest way to reclaim space without deleting anything you need.
