Hi, I have a big suggestion for the next update! My suggestion is to upgrade the call filtering system : - “Block suspicious calls” It automatically block numbers that are likely to be unwanted or spam. These calls should not ring, should not appear in the call history, and should be silently discarded. - “Block unknown callers/hidden numbers” Instead of receiving a call from a hidden or unknown caller and seeing it appear in the missed calls list, the call should be completely blocked and not recorded at all, no notification, no sight of call. - “Filter numbers that are not from contacts” If the same unknown number calls too frequently within a week and the user never answers (for example 10 times per day, or 5 times per day if considered suspicious or too much spam in a little time), the iPhone should automatically block this number. The device would display a message such as: “This number has called too many times and has been automatically blocked for 3 day(or 1 week).” The block could also apply to the entire IP range or source associated with the unknown caller. It is very helpful for most of unwanted calls.
