If you can't find your blocked numbers, start in the Phone app's Settings , look for the word "Block," and if all else fails, use the search bar in your main Android Settings . It’s there—Android just hides it differently depending on who made your phone.
If you’ve ever blocked a spam caller, an ex, or a persistent telemarketer, you might later need to find that list—either to unblock someone or to add a new number to the list. Unlike iOS, where settings are relatively uniform, Android’s fragmentation (Samsung, Google Pixel, OnePlus, Motorola, etc.) means the location of your blocked numbers can vary.
