System & Settings2

Set Date Manually

If the date field on your Samsung phone is greyed out, the device is still pulling the date from the mobile network. You need to turn off that automatic sync before you can pick a specific day, month or year yourself. This usually happens after a SIM swap, while traveling, or when testing an app that behaves differently on certain dates.

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
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
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.

Open
Other2

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
Calls & Messages2

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.

Open
Apps & Installation2

Change Default Apps

If tapping a link always opens the wrong browser, or a newly installed messaging app never launches automatically, a leftover default app assignment is still active. Samsung keeps separate default apps for actions like opening links, sending texts or making calls, and a fresh install does not take over automatically. Until you reassign it, the old app keeps handling those actions.

Open
Apps & Installation2

Show or Hide the App Drawer Button on the Home Screen

On Samsung phones the app list normally opens with a swipe up on the home screen, and many users miss the dedicated button from older models. If that swipe gesture feels unreliable or you simply prefer a fixed icon, a hidden home screen option lets you bring back a visible shortcut for the app list.

Open
Photo, Video & Media2

Reset Camera Settings

If your Samsung camera keeps producing odd results after tweaking resolution, filters, grid lines or shooting modes, restoring the default configuration usually clears the mess fastest. Custom settings like exposure values, watermark options or scene assist can silently stack up and cause blurry, oversaturated or oddly cropped shots. Resetting the camera app wipes every custom option but leaves photos and videos you already captured untouched.

Open
Display & Home Screen2

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.

Open
Network & Connectivity2

Turn USB Tethering On or Off

If your laptop or PC does not pick up an internet connection after you plug in your Samsung phone, USB tethering is probably still switched off. This feature routes your mobile data through the USB cable instead of Wi-Fi, which helps when public Wi-Fi is blocked, slow, or unavailable. Without the toggle enabled, the computer detects the cable but never actually goes online.

Open
Notifications & Focus

Change Notification Vibration Pattern

If every app buzzes your phone the same way, you cannot tell a message from a calendar reminder without checking the screen. Samsung phones let you pick a distinct vibration pattern just for notifications, separate from the one used for calls. A few built-in patterns are available, but the option is easy to miss since it sits away from the main sound settings.

Open
Apps & Installation2

Set App Timers

If one app on your phone keeps eating more of your day than planned, Samsung's App Timer can shut it down automatically once the daily budget runs out. The app closes itself and stays locked until midnight, then resets. Apps inside Secure Folder or dual-app clones are not affected by this limit at all.

Open
Photo, Video & Media2

Group Albums into Folders

When your Gallery fills up with dozens of separate albums, finding a specific event takes longer every time you open the app. Samsung lets you nest related albums inside one main album, so yearly or category folders stay bundled instead of cluttering the overview. This grouping option is easy to miss because it works through drag-and-drop instead of a settings menu.

Open
System & Settings2

Set Date and Time Automatically

If your Samsung phone shows the wrong time after a trip or a SIM swap, the automatic clock sync has likely been switched off. Apps that rely on accurate timestamps, like calendars, banking apps, or two-factor codes, can then throw errors or reject logins. This usually traces back to a single toggle in the system settings that pulls time data from your mobile network.

Open
Photo, Video & Media2

Delete Photos or Videos in Gallery

Storage warnings, an ex's photos, or a blurry shot that never should have been kept - there are plenty of reasons to clear out your Gallery. Deleting one file at a time works, but scrolling through dozens of photos or videos individually gets tedious fast. Samsung Gallery also routes deleted items into a Trash folder first, which confuses a lot of people expecting an instant, permanent delete.

Open
Storage & Backup2

Format SD Card

If your Samsung phone shows a damaged SD card message or won't read a memory card at all, the card usually needs to be formatted before it works with your device storage. This happens with brand-new cards straight out of the package and with cards that were previously used in a camera or another phone. No computer is needed - the format runs directly on the phone through Battery and device care.

Open
Calls & Messages2

Answer Calls Automatically

When your Samsung phone is paired with a Bluetooth headset, car kit, or hands-free device, incoming calls should connect the instant you accept them through the accessory. If Answer automatically stays off, you still have to tap the screen manually, which is awkward while driving or wearing a wired headset. The same setting also controls how many seconds pass before the call picks up on its own.

Open
Storage & Backup2

Restore Secure Folder Backup

If you set up a Secure Folder backup before resetting or switching your Samsung phone, the saved apps and files do not come back automatically. Samsung keeps that backup in the cloud, and you choose exactly which items to bring over instead of pulling the whole archive onto the device. Without an active internet connection, the restore option stays inactive.

Open
Display & Home Screen2

Home Screen Landscape Mode

Turning your Samsung phone sideways usually rotates apps, but the home screen itself often stays locked in portrait. That happens because the general 'Rotate to landscape mode' toggle only affects certain screens, not the home screen grid. A separate setting controls whether your app icons and widgets actually follow the rotation.

Open
Display & Home Screen2

Turn Samsung Free On or Off on the Home Screen

If the Samsung Free page with news and instant games keeps popping up when you swipe left on your home screen, you probably want to switch it off. Some users lose this page after a system update and want it back instead. The toggle for this panel sits away from the usual display settings, which is why it is easy to miss.

Open
Calls & Messages2

Block or Unblock a Contact

If one saved contact keeps calling or texting after you have asked them to stop, blocking is the only way to silence both channels at once. The tricky part is that a blocked contact stays visible in your contact list and cannot be hidden, which surprises many users. If you want to stop a number without ever saving it as a contact, a separate blocking method covers that case with the same effect.
