Activate a Downloaded Keyboard
A new keyboard from the Play Store shows up as installed but never appears as an option when you try to switch input methods. Samsung keeps every keyboard disabled by default until you turn it on in the keyboard management settings. Without this step, the downloaded keyboard stays invisible even though it is already on your phone.
Import Contacts from SIM or vCard File
If your contacts are stuck on an old SIM card or sitting in a vCard (.vcf) file, they won't show up in your phone until you pull them into the right account. Samsung phones can grab contacts from the SIM, internal storage, or a memory card, but picking the wrong source or target account is the most common reason the import seems to fail.
Turn Call Waiting On or Off
If a knocking tone interrupts your calls out of nowhere, or you never notice a second caller trying to reach you, Call waiting is probably set the way you don't want. This Samsung feature decides whether an incoming call during an active conversation gets signaled to you or blocked outright. Getting the setting wrong means either missed calls or unwanted interruptions mid-conversation.
Select Network Automatically
If your Samsung phone keeps losing signal or sticks to a weak carrier after you picked a network by hand, the automatic search feature is switched off. Once you select a network manually, Select automatically stays disabled until you turn it back on yourself. This mostly shows up while traveling or right after inserting a new SIM.
Show or Hide Calendar Accounts
The Samsung Calendar app lists every signed-in account, including My phone, Gmail, your Samsung account, App Events and Reminder, whether you want to see them or not. There is no option to permanently delete one of these entries from the calendar list. The only control you have is switching each account's visibility on or off.
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.
Move Contacts to Another Storage Location
If your contacts are split between the SIM card, the phone memory and a synced account, finding the right entry can get confusing fast. Samsung's contact app lets you shift entries from one storage location to another without deleting and re-adding them. This matters most when you swap SIM cards, switch accounts, or clean up duplicate entries after a sync.
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.
Turn Lock Screen Notifications On or Off
If notification icons keep showing up on your Samsung lock screen even though you want more privacy, or they suddenly stopped appearing at all, the Notifications setting under Lock screen controls that behavior. This single switch decides whether senders, message previews, or just small icons appear before you unlock the phone. Getting it wrong can mean missing calls or messages, or exposing content you would rather keep hidden.
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.
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.
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.
Allow Calls in Do Not Disturb
When Do Not Disturb is active on your Samsung phone, every incoming call gets silenced by default, even from people saved in your contacts. This happens because the Calls, messages and conversations settings inside Do Not Disturb treat phone calls like any other notification unless you tell it otherwise. You can choose whether all calls, only contacts, only favorites, or none get through.
Restore Default App Icons
Once you've applied a custom icon pack on your Samsung phone, there's no toggle in the app settings or launcher menu to bring icons back to their original look. The only place that reset lives is inside the Themes app, which most people never open again after installing a theme or icon set.
Sync Calendar Manually
If you close the Calendar app and it keeps running in the background, new appointments and logged calls on your Samsung phone often don't show up until you restart the app. Data saving mode, battery saving mode, and background restrictions in Samsung One UI can all block the automatic sync. Forcing a manual sync brings the calendar up to date without waiting for the next automatic refresh.
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.
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.
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.
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.
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.
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.
Keyboard Touch and Hold Delay
If long-pressing a key on your Samsung keyboard keeps popping up accent marks or symbols by accident while you type normally, the touch and hold delay is set too short for your typing speed. The opposite problem also happens: if you have to hold a key noticeably long before the alternate character menu shows up, the delay feels too slow for quick access to accents and special signs. Samsung lets you shorten or lengthen this response time instead of living with either annoyance.
Allow or Restrict Background Activity of Apps
If your Samsung phone loses battery fast even when you barely touch certain apps, background activity is often the reason. Some apps keep syncing, refreshing content or checking location while you are not using them, which quietly drains the battery between charges. You can turn this off for individual apps without disabling their notifications completely.
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.
