Set an Alarm

If you only see one alarm on your Samsung phone, it looks like you're stuck with a single wake-up time. The Clock app actually lets you add as many separate alarms as you need, each with its own time, days, name, tone and vibration pattern, but the option to create a new one isn't always where you expect it to be.

Open
Accessibility2

Reset Accessibility Settings

If Voice Assistant keeps reading out screen content, mono audio mixes both channels together, or color and contrast tweaks stay active without a clear reason, several accessibility options are probably still switched on from an earlier setup. Turning each toggle off manually is slow and easy to get wrong. The keyboard is not affected by this, so typing issues need a different fix.

Open
Calls & Messages2

Using Speed Dial Numbers for Calls

Speed dial numbers only work if you press and hold the correct digit on the dial pad instead of tapping it briefly. For two-digit speed dial slots like 14, you type the first digit normally and only hold down the second one. On phones with two SIM cards, missing the SIM selection step can also cause the call to fail.

Display & Home Screen2

Change Screen Mode

If your Samsung display looks too cool, too warm, or oddly oversaturated, the wrong screen mode is usually the cause. Samsung splits colour rendering into Vivid and Natural, and each mode reacts differently to the white balance slider. Picking the wrong combination makes photos, videos, and even white backgrounds look off.

Open
Apps & Installation2

Set Custom App Icons

If your home screen still shows the default Samsung icon set even after installing an icon pack from the Galaxy Store, the pack is downloaded but not switched on yet. One UI keeps custom icon sets separate from your current app grid until you apply them manually inside the Themes app. No root access or third-party launcher is required to activate them.

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.

Turn Alternative Characters On or Off

If the Samsung Keyboard suddenly swaps letters for symbols like the question mark, plus sign, or euro symbol while you type, the Alternative characters function is active. This can slow you down when you need letters and numbers mixed together, for example in passwords or addresses. A setting inside the keyboard layout controls whether this swap happens automatically.

Open
System & Settings2

Turn On/Off Assistant Menu

If reaching the physical Home, Back or volume buttons with one hand feels awkward, the Assistant menu replaces them with a floating panel of on-screen shortcuts. The panel can be dragged to any spot on the display and holds up to 12 buttons, but on many phones it stays switched off or shows shortcuts you never use.

Open
Network & Connectivity2

Connect to a Wi-Fi Network

If your Samsung phone shows no internet access or keeps dropping the connection at home, the Wi-Fi network is often not paired correctly yet. A saved profile with an outdated password can also block a new connection attempt. This mostly happens after a router change or a forgotten network entry.

Security & Privacy2

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.

System & Settings2

Schedule Auto Restart Times

If your Samsung phone slows down after weeks of uptime, a scheduled restart clears background clutter without you lifting a finger. Many users never notice the Auto restart at set times option because it sits deep inside the device care settings and stays off by default. Without it enabled, you are stuck rebooting manually every time performance drops.

Open
Display & Home Screen2

Change Always On Display Orientation

On Samsung phones, the Always On Display defaults to portrait orientation even when the phone sits flat in a stand, car mount, or dock turned sideways. That leaves the clock and icons rotated on their side instead of readable across the screen. The fix sits in a setting most people never open because it is separate from the normal screen rotation toggle.

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.

Turn VoLTE Calls On or Off

If calls sound muffled, take longer to connect, or switch to a spotty 3G signal mid-call, VoLTE might be turned off on your Samsung phone. Voice over LTE routes calls through your carrier's data network instead of the older 2G or 3G circuit, which affects voice clarity, connection speed and even battery drain. On dual SIM models each SIM line has its own separate VoLTE switch, so one number can sound noticeably better than the other.

Request Desktop Site in Samsung Internet

Some websites hide download buttons, settings pages or entire tools when Samsung Internet loads the mobile version instead of the full site. If a page looks stripped down or a feature just will not work, the browser is likely serving you the mobile layout by default. Forcing the desktop version brings back the complete site as it appears on a computer.

Open
Storage & Backup2

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.

Turn On/Off Bold Font

If every app on your Samsung suddenly looks like its letters gained extra weight, the system-wide Bold font toggle is likely active. This setting thickens all text, including fonts that are already bold, such as Gothic Bold, which can make some layouts look cramped or hard to scan. It sits separately from font size, so changing text size alone will not fix it.

Open
Network & Connectivity2

Unpair a Bluetooth Device

When a Bluetooth accessory keeps reconnecting automatically or you no longer trust a device on the list, removing the pairing is the only reliable fix. A simple disconnect just drops the current link but leaves the device saved, so it reconnects the next time it is nearby. Unpairing removes the stored connection completely and forces a fresh setup if you ever want to use it again.

Open
Network & Connectivity2

Set Up Mobile Hotspot with a Custom Name and Password

The first time you turn on the mobile hotspot on a Samsung phone, it broadcasts under the device name with an autogenerated password. That default network name is often confusing for guests and reveals your phone model to anyone scanning nearby networks. You can replace both the name and password before sharing your connection.

Delete an Alarm

When your Clock app fills up with old wake-up times, work alarms, and one-off reminders, finding the one you actually need gets tedious. A cluttered alarm list also makes it easier to accidentally leave an unwanted alarm active, which can go off at the worst moment. Clearing out unused alarms keeps your morning routine predictable.

Apps & Installation

Allow or Block Apps for Edge Lighting

Edge Lighting only reacts to the Messages app by default, so notifications from other apps never trigger the curved glow. If a supported app is missing from the list, it stays invisible on the edge screen even with its own alerts turned on. You can pick exactly which apps light up the edge or switch on a setting that covers all of them at once.

Turn On/Off Mono Audio

If you share headphones or only wear one earbud, stereo playback leaves you missing half the sound. Samsung phones split calls, music, and video audio across left and right channels by default, so a single ear only catches part of the mix. Mono audio merges both channels into one so nothing gets left out.

Network & Connectivity2

Change Preferred Network Mode

If your Samsung phone keeps dropping to a slower connection or won't pick up 4G or 5G even with full signal bars, the Network mode setting might be locked to an older standard. This option decides whether the device connects using 2G, 3G, 4G, or 5G, and a wrong choice here cuts off faster networks completely. On dual-SIM models each SIM slot has its own separate setting.

Floating Shutter Button: Turn On or Off

Selfies get tricky when the on-screen shutter icon sits out of thumb reach on a big display. Samsung's Camera app has a separate floating shutter release that you can drag anywhere on the screen, but it stays hidden unless you switch it on in the shooting methods. Without it enabled, you're stuck reaching for the fixed shutter icon or the volume keys every time.
