Edit and Reorder Edge Panel Contacts

If your Edge panel still shows outdated contacts or apps you never open, the panel content does not update on its own and needs manual editing. Positions also stay fixed until you rearrange them yourself, which often buries your most-used contacts at the bottom of the list.

Camera Timer: Set Self-Timer for Photos and Videos

Selfies and group shots often turn out blurry or rushed when you tap the shutter yourself, since the phone locks focus at that exact moment. The Camera app has a built-in self-timer that adds a countdown before the shot fires, so you can put the phone down and get into position first. On Samsung devices you can choose a delay of 2, 5, or 10 seconds depending on how much time you need.

Display & Home Screen2

Customize Secure Folder Name and Icon

If your Secure Folder still carries its default label and icon, anyone glancing at your app list can spot exactly what it hides. Samsung lets you rename it and swap the icon for something less obvious, but the icon options are limited to presets and the initial letter of your chosen name. You cannot upload a custom image as the icon.

Reset Advertising ID

If ads in apps still feel oddly personalized even though you never searched for those products, your Samsung Advertising ID is likely the cause. This identifier lets ad networks, including Google, connect your app activity into a profile used for targeted ads. Getting a fresh ID breaks that connection without touching your account or app data.

Turn Off Personalized Ads on Samsung

If ads in your apps feel oddly specific to sites you visited or things you searched, Google's Advertising ID is behind it. This ID lets ad networks build a profile from your app and browsing activity, then match ads to your interests across different apps and services.

Security & Privacy2

Set a Lock Screen with Pattern, PIN or Password

If your Samsung phone still starts up without asking for a Pattern, PIN or Password, anyone who picks it up can open your apps, messages and photos right away. Without an active screen lock, features like Secure Folder, Samsung Pass and biometric unlock cannot work properly either. Setting a real unlock method is the only way to keep the device locked between uses.

Vibration Alert for Missed Calls and Messages on Pickup

If your phone sits face-up on the desk, a missed call or message often stays unnoticed until you unlock the screen. Samsung phones can trigger a short vibration the moment you pick the device up, acting as a quiet catch-up signal. This depends on the 'Alert when phone picked up' option inside Motions and gestures, a feature many users never switch on.

Open
Language & Input2

Turn Predictive Text On or Off

Predictive text on the Samsung keyboard suggests words as you type, based on your past entries. If suggestions feel outdated, oddly personal, or simply distracting while you type, the keyboard's learning behavior is usually the cause. Turning predictive text off stops new suggestions and keeps the keyboard from adapting further to your typing history.

Security & Privacy2

Turn Google Play Protect On or Off

If Google Play Protect keeps flagging or automatically disabling an app you trust, the built-in scanner has classified it as suspicious. This often happens with sideloaded APKs or niche tools that Google has not verified, even when the app runs fine. Repeated warning notifications or a greyed-out app icon are the clearest sign that Play Protect is intervening in the background.

Apps & Installation2

Uninstall Secure Folder

Secure Folder can't just be deleted from your Samsung phone - it has to be uninstalled through its own settings menu. Confirming the uninstall wipes everything stored inside it, including apps, photos, contacts and documents. Once removed, you can set up a new Secure Folder from scratch later.

Factory Reset: Settings Guide

If your Samsung phone freezes, lags after a system update, or you are handing it over to someone else, a factory reset wipes the entire internal storage. Every app gets uninstalled and every linked account, including your Samsung account, is removed from the device. Once the reset finishes, none of that data can be recovered unless you saved a backup beforehand.

Notifications & Focus2

Change Timer Volume

The timer alarm on Samsung phones ignores the physical volume buttons and the usual sound settings, because it runs through its own separate slider. Users often turn up media or ringtone volume expecting the timer to get louder, but the timer stays at whatever level was last set inside the Clock app itself.

Open
Photo, Video & Media2

Delete an Album in the Gallery App

Deleting an album in the Gallery app on your Samsung phone removes the album and every photo or video inside it from the device, not just the album name. If Trash is not turned on, that content is gone for good with no recovery option. System albums like Camera cannot be removed this way.

Open
Network & Connectivity2

Select Network Manually

Near a border or while traveling abroad, your Samsung phone often locks onto whichever foreign network has the strongest signal, not the cheapest one. That automatic choice can mean higher roaming charges than a neighboring operator would offer for the same coverage. Switching to manual selection lets you pick the exact network yourself instead of leaving it to the phone.

Add or Remove Bookmarks in Samsung Internet

Typing the same web address every day gets tedious fast, and the Samsung Internet history list is not built for quick access to your favorite pages. Bookmarks solve that, but many users cannot find where to add a page or how to delete one that is no longer needed. Folders and sorting options add another layer of confusion once the bookmark list grows.

Open
Calls & Messages2

Turn On/Off Accidental Touch Protection

If your Samsung phone wakes up in your pocket or bag and taps random apps or dials contacts, the screen is registering touches it should ignore. This usually happens when the display turns on in a dark or enclosed space and the accidental touch protection feature is off or misconfigured. The result can be missed calls, sent messages, or apps opened without your knowledge.

Notifications & Focus2

Dialing Keypad Tone: Turn On or Off

Every digit you tap on the phone keypad triggers a short tone, and on some Samsung phones that sound plays even with the ringer muted. This comes from a separate system tone setting, not from the ringtone volume or a call app option.

Open
Security & Privacy2

Show or Hide the Lockdown Button in the Power Menu

Face Detection, Smart Lock and even the fingerprint sensor are convenient, but none of them is the strongest lock on your phone. Samsung adds a Lockdown entry to the power menu that forces a PIN, pattern or password before anyone gets in, overriding those biometric shortcuts. If that button is missing, or you want it gone for good, the toggle sits in a spot most people never check.

Security & Privacy2

Manage App Permissions via Permission Manager

When you install a new app on your Samsung phone, it starts with no access to your camera, microphone, storage or location. Only once you open the app or trigger a specific feature for the first time does a permission prompt appear on screen. If you tapped Deny by accident or want to review which apps can read your contacts, gallery or location, you need Permission manager to check and change each permission individually.

Open
Notifications & Focus2

Allow or Mute Alarm and Notification Sounds During Calls

If alarms and notification sounds keep interrupting your calls, or you cannot hear them at all until you hang up, the Notify during calls option is behind it. This setting decides whether the phone plays alert sounds while a call is active or holds them back until you finish talking. Getting the behavior you actually want means knowing where this toggle lives and what it affects.

Open
Calls & Messages2

Show or Hide Caller ID on Outgoing Calls

Your number pops up on the other person's screen even though you never turned that on, or it stays hidden when you need it visible for work calls. This behavior comes from a network-level default that Samsung phones inherit unless you change it in the phone app. The setting sits separate from Do Not Disturb or blocking and gets missed easily.

Open
Security & Privacy2

Lock or Unlock Home Screen Layout

If apps and widgets keep shifting position on your Samsung home screen, or a new app suddenly lands in the wrong spot, the layout is probably unlocked. This lets the system rearrange icons automatically and lets accidental long-presses move things around. Locking the layout stops both issues at once.

Open
Accessibility2

Turn Subtitles On or Off

If captions stay off during video playback or look different from app to app, you are probably dealing with two separate subtitle systems on your Samsung phone. Samsung subtitles and Google subtitles (CC) both add captions but sit in different menus and offer different styling options. Knowing which one is active decides whether size, color and background of the text can even be changed.

Apps & Installation2

Hide Apps from the Home Screen

If an app icon keeps cluttering your Samsung home screen even though you barely use it, uninstalling feels too drastic, especially for preinstalled apps you might need later. One UI has a built-in Hide apps option that removes the icon from the home and apps screens without deleting anything. The app stays installed, keeps running in the background, and is still listed in your full app settings.
