Facebook calling has many advantages like free calls, but you may sometimes be unsure about who is calling you because of a limited amount of caller information. As a result, Facebook has developed and released Hello, a caller ID and call blocking app for Android. Hello connects with Facebook to check who’s calling you so that the information from the caller’s Facebook profile appears directly on your screen. It also blocks calls from blocked contacts on your profile. You can also block specific numbers and choose to block calls from commonly blocked numbers. Calls from blocked numbers will go straight to your voicemail, where you can review them later. The app also allows you to search for people and businesses on Facebook and call them with a single tap, making it easier to connect with new people and organizations. You can download Hello for your Android device on the Google Play.
