If you often receive calls from an unknown number on your Samsung Galaxy S5, then this can be annoying in the long run. For this reason, there is the possibility of rececting unknown calls automatically in Android. We describe you now where you can find the setting to block unknown numbers on your Samsung Galaxy S5.
Open from the homescreen of your Samsung galaxy S5 the menu and then the Settings. Here you will find in the section "Applications" the button "Call". Tap this and then navigate in the menu next to "call rejection".
Tap at first "Auto Reject Mode" and checke in the new window, if "Auto reject numbers" is activated. If it is not marked yet, activate it now.
As next step go to "Auto Reject List", which now gives you the opportunity to put numbers on the so-called blocking list for calls. You already find here an entry with "Unknown". Set the flag in the checkbox behind it in order to automatically reject incoming calls on your Samsung Galaxy S5 received by unknown callers. That's it.
Now, if you get a undefined call on your Samsung Galaxy S5, then it is automatically rejected.
