How to Block a Number on an Android Phone

It is common for us to want to block a contact. Whether it is to reduce annoyance or dodge and unwanted circumstance, contact blocking has various benefits.  Nobody likes to be bothered by unknown contacts that call for advertisement. Therefore, most phone brands have included a ‘block contact’ option to help you get out of these sticky situations. It is a very simple process, so read on to know how to block a number on an android phone. The method is mostly the same, although the steps may vary a little depending on the handset model.

From Your Call Log:

On the call log display screen, you can select the name of the contact you want to block. Click on the three-dot pop-up menu in the upper-right corner of the screen and choose ‘Add to Reject/Block list’. Any incoming calls or messages from this particular number will be blocked by your phone until you change the setting.

From the Contacts List:

This works in the same way as blocking from the call log. You should first choose the contact you want to block. Then, click on the three-dot menu. Choose the ‘Block’ option to block the contact.

From Settings

Navigate to Settings > Call > Call Rejection > Auto Reject List > Create. After this, a search box will appear that will ask you to select the contact you want to block. Search for the contacts you wish to block and they will be added to the list.

Ask Your Service Operator

Your carrier can also block a phone number for you from the back-end. You can directly call customer care and simply ask them to do so. You will need to provide the phone number of the contact in order to stop receiving further contact requests from them on your mobile.

Using Third-party Apps

Third party apps also exist which can help in blocking contacts. But most of these apps are not compatible with anti-virus apps and therefore, may be a security threat to your operating system. Before choosing such an app, make sure you go through it user-reviews and run it through a virus-protection software.

Whatever the case, you can surely remove any contact trying to bother you unnecessarily using the protocols that are already in place for this purpose.
