Dialing #662# on your Android phone will block calls flagged as “Scam Likely”, but it won’t block spam calls in general. Like many other spam-blocking methods, this one doesn’t have any downsides, but it isn’t a complete solution, either. Here’s how to enable call blocking for “Scam Likely” phone numbers on Android: 1. Open your phone app and switch to the dial pad; 2. Dial #662#; 3. Tap the receiver icon like you would when calling a regular number.
