At times, we choose to ignore some person’s call due to a couple of issues. Maybe to avoid disturbance, or not wanting to talk to them at all due to something bad they did. At best, we block calls to avoid telemarketers, scammers and those unwanted network provider calls that say nothing reasonable but want you to opt-in for a service.

In this post, I will show you how to easily block a number from calling you on Android phones.

How to Block Calls From a Number on Android Phone
Open the Dialer App on your phone and navigate to your recent calls list.
Find the contact you want to block, tap call details and select Block/Report Spam.
If you wouldn’t like to report the number as spam, you can uncheck the box and proceed to tap Block.
Hope you find this helpful.
