Its actually a now a setting on call settings as appose to just an app you dont need to be singed up or registerd with them to get the information wich is some ones full name when they call you only came across this as i have a new handset the s9+ (android,) its also a setting on iphone x (apple) I freaked thinking people may get my real full name if i called or txt them back but apparently not as i havent registerd but always good to share it may even be included in software updates just be vigilant xx
