Turn Sticker Suggestions On or Off

Stickers and emoji suggestions from Bitmoji or mojitok can pop up every time you type on a Samsung keyboard, even in apps where you don't want them. This happens because sticker suggestions run as a separate function from regular word prediction. You can also choose which apps are allowed to show these suggestions.

Turn On/Off Dialing Keypad Vibration

If every digit you tap on the dial pad triggers a buzz you don't want, or the phone stays silent when you expect haptic feedback, the dialing keypad vibration setting is behind it. This option controls whether Samsung phones give a short vibration for each key press while dialing a number. It sits under the general vibration controls, separate from ringtone or notification vibration.

Add Emergency Contacts

If your phone is locked during an emergency, nobody can reach the people you trust unless they are saved as emergency contacts. Samsung ties this list to your Contacts profile, not to your regular address book, so numbers you already have saved will not show up on their own. Without this setup, SOS messages and lock-screen emergency calls have nobody to go to.

Turn On or Off Automatic QR Code Scanning

If your Samsung camera no longer picks up QR codes while you're in normal photo mode, the automatic QR scanning function is probably switched off. Older Samsung devices used a separate scan mode for this, but current models detect codes directly through the standard camera view. When the option is disabled, pointing the camera at a code does nothing at all.

Apps & Installation2

Install Print Service Plugin

If your printer does not show up when you try to print from your Samsung phone, the built-in print service most likely does not cover your printer model. Samsung ships with a standard print service that works with popular brands, but many manufacturers require their own plugin to print files correctly. Without that plugin, print jobs either fail or the printer never appears as an option.

Apply Camera Filters

Standard shots from the Samsung camera app come out flat and natural, but you want a specific look like black and white, sepia, pale or a warm tone instead. The filter options sit in their own menu that is easy to overlook, and the intensity control for an applied filter goes unnoticed just as often.

Turn Vibrate When Call Ends On or Off

If your Samsung phone buzzes right after a call disconnects, that comes from a separate call alert, not your regular vibration mode. Some people rely on the buzz to notice a dropped call without checking the screen, others find it jarring when it fires during a meeting. The setting sits inside the Phone app rather than the general sound profile, which is why silent mode alone does not always turn it off.

Calls & Messages2

Change SMS Input Mode (GSM or Unicode)

If a single text turns into two or three messages the moment you add an emoji, the input mode set for text messages is the reason. GSM alphabet only covers basic Latin characters, so any emoji or special symbol forces the message to switch encoding and split. Automatic or Unicode mode prevents that, but it can affect how many messages you get billed for.

Copy a Text Message

Retyping a message just to paste an address, a code, or a link somewhere else costs time and often introduces typos. On Samsung phones the Messages app lets you grab the exact text of any message and copy it to your clipboard for reuse in another app.

Add a Printer by IP Address

If a printer never shows up in Samsung's Default Print Service, that model is likely not supported by the built-in driver list. Without a manual entry, print jobs simply fail or the printer never appears as an option. This mostly affects office, network, and older printers that the standard service does not recognize automatically.

Turn Video Stabilization On or Off

If your videos look shaky despite recording handheld, or clips from the main camera suddenly seem oddly smoothed and slightly cropped, Video stabilization is the setting behind it. Samsung enables this correction by default, but only on the main camera, so footage from other lenses will not look the same. In fast pans or low light it can also introduce a subtle wobble or crop that some people prefer to turn off.

Change Data Warning Limit

If your mobile plan comes with a fixed data allowance, going past it without noticing usually means extra charges or a throttled connection. Samsung's data warning is meant to flag that moment, but the default threshold rarely matches your actual plan. Unlike the data limit, this feature only sends a notification and leaves your connection running.

Notifications & Focus2

Customize Lock Screen Notification Style

By default, Samsung phones show a small app icon on the lock screen for every new notification, without any details. If you want to see who messaged you or read a preview before unlocking, that icon-only view can feel too limited. One UI lets you switch between a compact icon and a full notification card, including options for hiding content or adjusting background transparency.

Display & Home Screen2

Add Widgets to the Home Screen

Looking for a widget on your Samsung home screen but only finding app icons? One UI keeps most widgets tucked away in a hidden menu instead of showing them next to your apps. This applies to pre-installed widgets like clock, weather or radio, and to any widgets added by apps you install afterward.

Set Up Universal Switch for Hands-Free Control

If tapping the screen or pressing buttons is difficult, standard touch controls quickly become a barrier on a Samsung phone. Universal Switch lets you trigger taps with head movements, facial gestures, or an external switch instead, but the setup only works if the front camera can track your face reliably. Poor lighting or an unclear gesture pattern often causes missed or accidental actions.

Add an Alternate Calendar

If dates on your Samsung calendar don't match the Lunar, Hijri, or Shamsi calendar you expected, the alternate calendar option is probably switched off. Samsung's Calendar app can show a second calendar system in smaller text next to the standard dates, but it stays hidden until you set it manually in Settings. This affects the Korean, Chinese, and Vietnamese Lunar calendars as well as Hijri and Shamsi dates.

Add Birthday to a Contact

If a friend's contact card in Samsung Contacts has no space for a birthday, the field is not missing - it is just hidden by default. Samsung keeps birthday, anniversary and other important dates tucked away behind an extra menu step, so most people never notice it exists. Once you know where to look, adding the date takes only a few taps.

Record a Video with the Camera App

Tapping the shutter on your Samsung phone only takes a photo, even though you wanted to film a clip? The Camera app opens in photo mode by default, so recording a video means switching modes first. Once you do, the viewfinder gets noticeably smaller - that's normal, since video uses a different resolution than still photos.

High Contrast Keyboard: Turn On or Off

If the stock keyboard is hard to read in bright light or the keys feel too small, a low-contrast color scheme is usually the cause. Samsung Keyboard has a built-in 'High contrast keyboard' mode that swaps the color scheme and enlarges key size at the same time. Availability and exact designs vary slightly depending on the Samsung model you use.

Network & Connectivity2

Turn Bluetooth Tethering On or Off

If your tablet, laptop, or smartwatch can't get online through your phone's Bluetooth connection, Bluetooth tethering is probably switched off. This feature turns your phone into a small Bluetooth hotspot and shares its mobile data with every paired device automatically.

Print a Photo from the Gallery

If the Print option in your Gallery stays greyed out or no printer shows up, the built-in printing service on your Samsung phone or tablet is not finding a compatible printer. This happens most often when the printer is on a different network or the print plugin has not been set up yet. The result is that photos, PDFs or other files never reach the printer, even though the Print button is right there in the share menu.

Default Reminder Time for Calendar Events

Every new event in Samsung Calendar starts with a reminder set to 10 minutes before, and all-day events default to 5 p.m. the day before. If you keep adjusting these values by hand for each new entry, the app is falling back on its built-in alert defaults instead of your preferred timing. Changing the default once removes the need to reset the reminder every time you add an event.

Change Ringtone Volume

If your phone barely rings during incoming calls even though media volume is turned up, the volume keys are probably adjusting the wrong stream. On many Samsung phones, pressing the side buttons on the home screen changes media volume by default and leaves the actual ringer level untouched.

Change the Billing Cycle Date

If your data usage counter resets on the 1st of the month but your carrier bills mobile data on a different day, the numbers on your Samsung phone never match your actual invoice. This mismatch comes from a fixed billing cycle date in the data usage settings, not from a tracking bug. Adjusting the start date lines up the on-device counter with your real billing period.
