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.

Calls & Messages2

Send a Group Text Message

Typing out the same text to five people one by one gets old fast, and picking each contact by hand in Messages is easy to mess up. If you already saved a group of people in Contacts, there is a faster way to reach everyone at once without adding them individually. The trick is knowing where the Groups option actually sits inside the Messages app.

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
Storage & Backup2

Turn Google Drive Backup On or Off

If your Samsung phone seems to back up the same data twice, Google Drive backup might be running alongside Samsung Cloud without you noticing. This can quietly eat into your Google storage or leave you unsure which backup actually holds your latest photos and app data. Knowing where this toggle sits helps you decide which backup system to rely on.

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.

Delete a Conversation

Deleting single texts one by one takes forever when an entire chat thread is cluttering your Messages app. On Samsung phones you can remove a full conversation at once, including every SMS or MMS it contains, instead of clearing messages individually.

Change Mobile Data Usage Limit

On many Samsung phones, mobile data cuts off automatically once usage hits a limit you never chose yourself. The phone applies its own default cutoff instead of a value based on your actual plan, so the connection can drop mid-month without warning. Mobile data only comes back once the new billing cycle starts, unless you raise the limit yourself.

Open
Display & Home Screen2

Create a Folder on the Home Screen

Your Home screen fills up fast when every app gets its own icon, and scrolling through several pages just to find one app gets tiresome. Samsung lets you group icons into folders, but the option only shows up once you enter the icon selection mode instead of a regular menu. Missing that step is usually why people give up before finding Create folder.

Open
Battery & Power2

Turn Adaptive Battery On or Off

If notifications from an app you rarely open arrive late or not at all, Adaptive battery is probably holding that app in a deeper sleep state in the background. The feature only limits background activity for apps you barely use and leaves apps you open daily untouched. It has no effect on screen brightness or overall device performance, so switching it off will not speed up your phone.

Open
Network & Connectivity2

Connect to Wi-Fi via QR Code

Typing out a long WLAN password on a guest's phone wastes time and usually ends in a typo or two. Samsung's Wi-Fi QR code scanner reads the network credentials straight from another device's shared code, so you skip manual entry completely. The catch: the other device has to generate and display that QR code first before your phone can scan it.

Open
Notifications & Focus2

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.

Open
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
Apps & Installation2

Install an App from the Google Play Store

On a Samsung phone you can install apps through the Google Play Store or through Samsung's own Galaxy Store, and it is not always obvious which one to use for a given app. The Play Store covers most mainstream apps, while some Samsung-specific tools only show up in the Galaxy Store. Picking the wrong store or getting stuck on the search results is the most common reason an install never starts.

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.

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.

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
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.

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.
