If you want to block a phone number on your Android device, there are a few different ways to go about it. The first way is to go to the Settings menu on your device and select “Phone”. From here, you will be able to see all of the phone numbers that are currently registered on your device. To block a number, simply tap on it and select the “Block this number” option. This will prevent anyone from calling or texting that number from your device. If you want to unblock a number later, simply go back to the Phone menu and select “Unblock this Number”. This will allow people who have been blocked by you to call or text you again. ..
