OMG this app came standrd with the my upgrade to android 9. Aftr a couple days I was wundrn why my fon was so quiet. Aftr a lil nvestigatn I discoverd ths app was blockn all my calls- sendn a msg to callers sayn that I was usin a screenin app that didn't allow any calls from anyone who wasn't n my contacts instructn callrs to send a msg stating who they r to b white listed & try calln again! It's really nice f u have allota sales calls! But I also missd several importnt calls! Also wrong IDs
