A feature that's apparently been around a while on Samsung phones is getting lots of buzz this week after someone on Reddit spotted a how-to in a user's manual. It includes a handy section on "Fake Calls"—making your phone ring in simulation of a real incoming call—for "when you want to get out of meetings or unwanted conversations," notes Gizmodo. And just think: no app needed. It's not clear which model the manual is from. See the Gizmodo link for a screen shot of it.
