Select the number you want to block. On a Samsung phone, tap Details. If your carrier supports blocking, you'll have a menu item called something like "Block number" or "Reject call" or perhaps "Add to blacklist." If you're using a different Android phone, like a Pixel, you might do the following after you find the number you want to block in your Phone app: Tap the vertical dot menu in the upper right corner of the screen.
