How to block specific phone number or all unknown numbers on your Samsung Galaxy S21 phone. It’s easy to block a number on your Samsung Galaxy S21. You can block all unknown or private numbers and add specific phone numbers to the blocked numbers list on your Samsung Galaxy S21 phone.
To block a phone number on your Samsung Galaxy S21, open the Settings menu in the Phone app and choose the Block numbers option. To make it easier to enter numbers, you can copy phone numbers from the recent calls list in the Phone app and paste them into the Block numbers list.
Your Samsung Galaxy S21 makes it easy to block the phone numbers of strangers, individuals or specific contacts. You can block all calls from unknown numbers and also block specific numbers, let’s see how.
How to block a number on Samsung Galaxy S21 via the Phone app
Samsung Galaxy S21 like any other Android-based model has a «Phone» app. It allows not only to make phone calls, but also to block spam and unknown numbers. To add a contact to the blacklist follow the instructions:
- Open the “Phone” app.
- Go to the contact list.
- Open the contact.
- Click on the button, which looks like three dots and select «Add to blacklist».
After completing and confirming these steps, you will no longer see the caller name on the device screen. If the contact is not in your address book, they can be blacklisted via the call logs.
How to blacklist a number via third-party apps
The problem of unwanted calls bothers not only the creator of the Samsung Galaxy S21, but the third-party developers as well. They have prepared many apps with a blacklist function, which works like a normal dialer.
Then, you can use the “Call Blocker” app. It is available on Google Play and suggests the whole range of opportunities to get rid of annoying contacts. You can add the number to the blacklist via the call log or by entering contact information.
Also, there are other similar programs. For example, «Call control». It looks different but has the same “Call Blocking” features, so you won’t have any problems with it.
Block numbers in messaging apps
Even if you have blocked a person using one of the above ways, they have the opportunity to talk to you in other ways. For example on WhatsApp, Telegram or Viber if the messenger is connected to the same number.
The way out of the situation is simple: blocking numbers in messaging apps. To do this, click on the appropriate button in the chat with an unwanted member. It appears when you receive the first message from the person. If the “Lock” function does not appear on the screen, press the button, which looks like three dots, and select the similar item.
This option works the same way in other messengers like Whatsapp, Telegram or Viber. Each application has its own blacklist with the help of which annoying callers are blocked.
How to block private number on Samsung Galaxy S21
Sometimes people call you from anonymous numbers. Then «Unknown» appears in the name field and blocking with the standard modes becomes impossible. In a similar situation, you need to find an additional option that may have been added to the firmware version of your Samsung Galaxy S21:
- Open the settings on your device.
- Go to the app list.
- Select “Calls” or “Phones” (the program name may differ depending on the version of the operating system).
- Go to «Antispam» and then to «Block calls».
- Set “Block calls from strangers” and “Block calls from hidden numbers” to the active position.
As you do the last step, don’t confuse these options. The first blocks incoming calls from any person who is not included in the contact list, and the second – only from hidden numbers.
Don’t worry if you can’t find the option. There are many programs that work this way. For example, “Call barring”.
