Storage & Backup

Restore a Local Backup

If your Samsung phone still shows old photos, contacts or settings after a factory reset, the backup saved to your memory card, USB stick or external drive was never applied. Local backups live outside your Samsung account, so the system will not pull them in automatically. You need to trigger the restore manually through the storage transfer settings, and this works on any Samsung device, not only the one that created the backup.

Open
Display & Home Screen2

Change Home Screen Grid Size

If icons on your Samsung home screen look too large or too small, or too few apps fit per row, the Home screen grid setting is likely still on its default layout. Switching between 4x5, 4x6, 5x5, and 5x6 changes how many app shortcuts appear per screen and how big each icon renders. This also affects spacing on the app screen, not just the home screen.

Clear Browsing History in Samsung Internet

If Samsung Internet keeps suggesting old searches or autofilling addresses you would rather forget, your browsing history is probably still full. The browser stores every visited page except the ones opened in secret mode, and that list keeps growing until you clear it manually. You can remove a single entry or wipe the entire history at once.

Toggle Screen Brighten for Face Recognition

Unlocking your Samsung phone with your face in a dark room briefly floods the display with light, and that flash can be distracting or draw attention at night. This behavior comes from the Brighten screen option tied to Face recognition, and it works independently from your normal screen brightness settings.

Calls & Messages2

Send a Text Message (SMS/MMS)

Your text keeps splitting into multiple parts or a photo won't attach when you try to send a quick message on your Samsung phone. Both issues come down to how the Messages app switches between SMS and MMS depending on content and length. Knowing which mode is active helps you avoid extra charges and failed sends.

Clear Samsung Internet Browser Cache

If Samsung Internet keeps showing an outdated version of a website, images that will not update, or a page that fails to load correctly, stored cache files are usually the cause. The browser saves data locally to speed up loading times, but that same cache can hold on to broken or old content. Clearing it forces the browser to fetch a fresh copy of the page.

Open
Photo, Video & Media2

Change Screenshot File Format

By default, every screenshot on your Samsung phone gets saved as a JPG, which compresses the image and can slightly soften text or fine details. If you need sharper captures for documents, UI comparisons, or editing work, JPG's lossy compression becomes a real limitation. Switching the format to PNG keeps every pixel intact at the cost of a slightly larger file size.

Open
Security & Privacy2

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.

Storage & Backup2

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.

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.

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.

Open
Notifications & Focus2

Set Temporary Mute Duration

If your Samsung phone stays silent for a full hour when you only wanted ten minutes of quiet, the Temporary mute default is working against you. Mute mode starts with a fixed one-hour timer unless you change it, so calls and alerts stay blocked longer than planned. That gets annoying fast when you only needed silence for a short meeting or a quick errand.

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
Notifications & Focus

Turn Navigation Gesture Vibrations On or Off

Every tap on the navigation bar buttons triggers a short buzz on your Samsung phone, and that constant vibration gets annoying fast if you swipe through apps often. The feedback comes from a separate haptic setting for navigation gestures, not the general vibration toggle, so switching off standard notification vibration does not stop it. You need the dedicated system control instead.

Open
Storage & Backup2

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.

Open
Notifications & Focus2

Turn Notification Reminders On or Off

By default your Samsung phone only announces a new notification once, with a tone or vibration depending on the sound mode. If you tend to miss messages because you were busy or the screen was off, a single alert is not enough. Notification reminders let the device nudge you again at a set interval until you actually open the notification.

Open
Apps & Installation2

Force Stop an App

When an app on your Samsung phone stops responding, swiping it away from the recent apps overview usually does not help. That gesture only tells the app to wrap up background tasks, it does not kill a stuck process. If a software glitch is blocking the app, it keeps running in the background, drains battery, or leaves the screen frozen.

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.

Open
Other2

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
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.
