However, we cannot directly recognize whether the incoming phone number is or not a trustworthy one. As considerate as Samsung is, it comes out with a feature named "Identify Unsaved Numbers". For more information, please go on reading this article.

Section 1: A Brief Introduction to 'Identify Unsaved Numbers'

"Identify unsaved number" is a feature that is designed to identify numbers that are not stored in your Contact List and alerts you when an incoming call may be a nuisance call or spam.

When you receive a call from a number not in your address book, the Samsung Galaxy S7/S8 can check to see if that phone number is suspected of being a spammer or even a fraud-related number, and what the risk level is. Depending on that analysis, you can choose to block or report the number. How sweet, right?

More than calls, this function can prevent from messages hassle in the same way, though it's only available in some certain countries so far. To learn how to enable this feature, please read on.

However, some have reported that they found the 'Identify Unsaved Numbers' grayed out for no reason. How come? As I've stated above, this function only works in some countries. Or, you might drill down these three workarounds one by one.

Some bugs or glitches will be fixed in the latest operating system. So, if there is an update, please upgrade your Samsung, especially if you haven't update your device for long.

Approach 2: Restart your cell phone and try again.

If this is a temporary issue, then you might get it solved in this way. To power off you Samsung, please hold down the "Power" button and tap on "Restart". If you wish, you can turn the device off and then manually boot it up anew.

Approach 3: Reboot the system.

However, it's more of a tech staff. Please follow the exact steps. At first, you should boot Samsung into Recovery Mode. Power your Samsung off completely at first. Next, hold down "Home(Bixby on S8)+Power+Volume Up" buttons at the same time. When Samsung logo shows up, immediately let go of the keys. When in Recovery Mode, you should use "Volume" keys to choose "Reboot system now" option and confirm via "Power" button. Then, wait until it's done.
