Consistency Is Evolving

Overall, call blocking features on Galaxy phones have evolved over the years to improve their elegance, flexibility, and compatibility with call blocking capabilities on other Galaxy and non-Galaxy models. However, standardization of these features across all Galaxy phone models, from all carriers, hasn't quite happened.

Certain features appear on some Galaxy phones, but not all. You'll also encounter variations in the terminology and icons appearing in menus. For instance, what was once known as the Auto reject list on Galaxy phones is now typically called the Block list. Unknown callers might instead be referred to as Anonymous callers or as Contacts without numbers.

Reasons for the Differences

The version of Android you have installed on your phone partially dictates call blocking capabilities. From the Galaxy S5 to the S9 alone, Samsung moved from Android 4.4 KitKat to Android 8.0 Oreo, with wireless carriers adopting these versions at their respective paces.

In its online documentation for the Galaxy S6, for example, T-Mobile describes two different techniques for blocking phone numbers; one method is for a Galaxy S6 running Android 5.0 Lollipop, while the other is for Android 6.0 Marshmallow. If you've updated an older Galaxy model to a more recent version of Android, your call blocking features may have changed, too.

Complicating matters further is how wireless providers differentiate their phones through the feature sets they offer; despite being the same phone, a T-Mobile Galaxy S9 may differ from a Galaxy S9 sold by Verizon or AT&T.

What Else Can You Do?

If these methods and their variations don't work for you, search online for carriers' product manuals for their editions of various Galaxy series. Alternatively, contact your provider for specifics about how to block phone numbers on your specific Galaxy phone model.

You’ll find plenty of third-party call blocking apps available, too.
