Turn Power Saving Mode On or Off
When your Samsung battery drains faster than usual, Power saving mode limits background data use and blocks location lookups for apps you are not actively using, while stretching what charge is left. Depending on the model, it can also turn off Always On Display and lower CPU speed, so screen behavior and app performance change until you switch the mode back off.
Send a File via Wi-Fi Direct
Sending a large video or a batch of photos over Bluetooth on your Samsung phone can take minutes, and pairing devices first adds another step. Wi-Fi Direct skips the pairing process entirely and moves data at much higher speed, which matters when the recipient device is nearby and Bluetooth transfer rates are too slow.
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.
Change USB Connection Mode
After the first cable connection, Samsung remembers whatever USB purpose you picked and stops asking again. If that means your phone keeps loading as Charging only instead of File Transfer, moving photos or documents to a computer stops working until you switch the mode manually.
Filter Call History by Type
When your Samsung call log mixes missed, rejected, and outgoing calls together, finding one specific entry gets tedious fast. A built-in filter narrows the list down to just what you need, for example missed calls only or calls tied to one SIM. This works on any dual-SIM Samsung phone.
Turn Wi-Fi On/Off Automatically
If your Samsung phone switches Wi-Fi on or off without you touching a toggle, One UI's location-based automation is running in the background. The feature remembers networks tied to places you visit often and toggles Wi-Fi accordingly when you arrive or leave. This can drain the battery faster than expected or leave your phone offline at home when the location was not recognized.
Add Alarm Widget to Home Screen
Checking whether tomorrow's alarm is still active means opening the Clock app every time, even for a quick glance. Samsung's Alarm widget puts a single alarm directly on your Home screen, so you can switch it on or off and see the time without unlocking into the app. Each widget only tracks one alarm, so multiple alarms need one widget each.
Change the Default Homepage in Samsung Internet
Samsung Internet opens with Quick access by default, a screen full of shortcuts to sites like Google, eBay or Tchibo instead of the page you actually want to see. You can switch to a personalized start view, the most-visited sites list, or a fixed web address of your choice. The option sits inside the browser menu and is easy to overlook the first time you look for it.
Show or Hide Calendar Week Numbers
If your Samsung Calendar does not show which calendar week you are currently viewing, the week number display is probably switched off. Without it, planning around ISO week numbers for invoices, shifts, or project deadlines means counting weeks by hand. The option sits inside the calendar app itself, not in the general phone settings.
Add a New Contact
Typing a number straight into the dialer only leaves it in your call log, not in your address book. If you clear that history or set up a new phone, the number is gone for good. The Samsung Contacts app is the only place that permanently stores a name together with a phone number and any extra details you add.
Switch Between Open Tabs in Samsung Internet
With several tabs open in Samsung Internet, finding the right one again can take a few tries, especially once previews start looking alike. Some tabs also seem to reload from scratch every time you switch back to them. There is more than one way to jump between tabs, and one of them is a lot faster than tapping through the tab overview.
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.
Turn Data Roaming On or Off
When your Samsung phone connects to a foreign carrier network instead of your home network, mobile data stops working until Data roaming is switched on. That is fine while you stay close to home, but abroad it blocks emails, maps and apps from loading over the mobile network. Switching it on without checking your plan first can also lead to unexpected charges.
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.
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.
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.
Mark a Contact as Favorite
If a contact you call or text often keeps sliding down your list, Favorites pins them to the top - but only once the flag is actually switched on for that person. On Samsung phones this same flag also controls the pinned row in the Phone app, so the two lists never match up on their own.
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.
Switch Between Front and Rear Camera
Jumping from a landscape shot to a quick selfie shouldn't mean closing the Camera app and reopening it. On Samsung phones the front and rear lenses share one interface, but the small switch icon is easy to miss if you're not looking for it. Knowing exactly where it sits saves you from fumbling mid-shot in both photo and video mode.
Enable Grid Lines in Camera
Framing a shot by eye often leaves the horizon tilted or the subject off-center in the final photo. Samsung cameras include an on-screen grid overlay meant to fix this, but many people never notice the toggle or don't know which pattern fits their shot. Portraits and landscapes benefit from different grid styles, so picking the wrong one still leaves composition guesswork.
Turn On/Off Wi-Fi and Bluetooth Scanning for Location Accuracy
If your Samsung phone places you several streets away from where you actually are, especially downtown or inside a building, GPS satellite signals alone are not reliable enough. Samsung adds a scanning feature that cross-checks nearby Wi-Fi networks and Bluetooth devices to close that gap, and it can be switched on or off independently. Knowing when this setting helps and when it just drains extra battery makes a real difference for accurate tracking.
Answering an Incoming Call
If tapping the green call icon does not seem to pick up the call, a single tap is not enough on Samsung phones. The call screen looks different depending on what you were doing before it rang: full screen when the phone was idle, a small pop-up window at the top when you were already using an app. Knowing which layout you are looking at changes where and how far you need to drag your finger.
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.
