  1. Download and install Truecaller on your Android phone. Download – Truecaller
  2. Open Truecaller and select the Calls tab and tap on a side arrow icon.
  3. Select Block from the following menu. If you don’t prefer Truecaller, there is no drought of call blockers apps on the Play Store. However, be careful while installing any random app from the Play Store. Some apps are simply adware trying to push malicious ads on your Samsung phone.
  4. If I block calls, does it also block text or internet messages? When you block spam calls on your Galaxy phone, the system blocks text messages from the same number too. However, the person can still reach you via WhatsApp, Messenger, Telegram, or Signal. If you completely want to cut ties, block the person on social media platforms too.  
  5. What if I want to block calls but not messages? If you only want to block calls, use third-party apps like Truecaller. In this case, you will continue to get text messages from the recipient.
  6. If I block calls on my Galaxy phone and switch devices, does it remain blocked? Samsung doesn’t sync your blocked numbers list with a Samsung cloud or Google Drive. When you switch to another phone, you must block irritating numbers again.
  7. Does the caller know about being blocked? When you block someone, the system doesn’t send any alert to the person. But when you remain unreachable for a few months, the recipient may take an educated guess about being blocked.
