NOTE: For this tutorial, I used a Google Pixel 6a running Android 14 and a Samsung Galaxy A54 with OneUI 6.1. When things are too different between the two Android flavors, I cover them separately. The steps are similar on all Android-powered devices, so you should be good to go even if you have a smartphone from another manufacturer like OnePlus, Xiaomi, Oppo, or Motorola. If you don’t know your Android version, here’s how to check the Android version on your smartphone or tablet.

How to block a number (calls and texts) on Android using the Contacts app

By default, your Android smartphone offers several ways to stop a number from calling and messaging you. If the number you want to block is saved on your smartphone, the easiest way to do this is from the Contacts app. First, open the All Apps screen by swiping up on the Home screen.

How to permanently block a number on Android, using Google’s Contacts app
