For about 2 weeks no one has been able to call my wife, the classic automatic answer always comes in, and so yesterday I hacked into her phone and saw that by default all unknown numbers are blocked, so I unblocked it and now she receives calls. Except that all numbers that call my wife appear as private or unknown. Basically what happens is that strangely the phone (and without any system update in the last few weeks) for no reason, stopped recognizing all known and registered numbers in the phone, and therefore for exactly this reason blocked calls. Has this ever happened to you?
