I like the Apps I can get with my android smartphone though.
Trucaller let's me add all the info about callers that I need at a glance, plus their address directly links to Google maps, so I can immediately inform them of ETA when they call to book again.
I block literally dozens of timewasters per week, but I can check the spam folder from time to time (see if anyone has become stalkerish/potentially a threat)
Personally, I could never go back to my teeny little Samsung clamshell (unfortunately
)
