Call filtering app?
Out of bunch of anonymous there on Gplay, is there any light&fast&simple&invisible call filtering app you'd like to recommend for Xperia Z series? I've tried dozens and most of them are quite bulkish, oldish, semi-faulty and definitely visible like flashing or notifying etc. hanguping after first ring, disconnecting too obvious for a caller, really poor solutions.. Any thoughts?
