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.

Storage & Backup2

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If Samsung Internet keeps showing an outdated version of a website, images that will not update, or a page that fails to load correctly, stored cache files are usually the cause.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.

Network & Connectivity2

Turn Location (GPS) On or Off

If navigation apps cannot find your position or refuse to load a route, Location access is often switched off on your Samsung phone. Weather widgets, Find My Mobile, and location-tagged photos rely on the same GPS toggle, so one setting affects several features at once. Turning it off saves battery but breaks any app that needs your real-time position.

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.

Security & Privacy2

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.

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
Battery & Power2

Turn Maximum Power Saving Mode On or Off

When your Samsung phone suddenly runs painfully slow, background apps stop updating, and the Always On Display disappears, Maximum power saving is likely active. This mode cuts CPU speed to roughly 70 percent, blocks most background data, and only allows a limited number of apps to run. If you turned it on for an emergency and now need full performance back, or you want to switch it on before a long day away from a charger, you need the correct toggle in Battery settings.

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
Calls & Messages

Mark All Messages as Read

When messages pile up from several conversations, opening each chat just to clear the unread badge gets tedious fast. On Samsung phones, unread counts can stack up in the Messages app, especially after being offline or on Do Not Disturb for a while. A single option lets you clear every unread badge without tapping into each conversation one by one.

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.

Close All Tabs in Samsung Internet

Too many open tabs in Samsung Internet slow the browser down and make it hard to find the page you actually need. Scrolling through dozens of thumbnails just to spot one tab wastes time and drains memory. Closing unused tabs regularly keeps the browser fast and responsive.

Open
Notifications & Focus2

Turn Keyboard Sounds On or Off

Every tap on the Samsung keyboard triggers a click sound that can get annoying, especially in quiet rooms or during calls. This tone runs independently from your ringtone, notification and media volume, so lowering those won't silence it. Two separate settings areas manage the keypad tone, and mixing them up is the usual reason one toggle does not seem to work.

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
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
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.

Open
Photo, Video & Media2

Disable Autoplay Videos in Samsung Internet

Videos embedded in web pages start playing the moment a site loads in Samsung Internet, even over mobile data. That eats into your data plan and drains the battery before you have tapped anything on the page.

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.
