Rummaged through a bunch of articles in search of an answer to this question, but nothing helped. I ask for your help.
Android 6, LG
The contact book displays only a part of the numbers (124 contacts from applications such as Skype, Weiber, etc.), but in fact there should be much more contacts and they are in the phone (confirmation of that - when entering phone number +7 there are 449 numbers).
How can I make these 449+ contacts appear in the contact book?
In the display settings of contacts, it is possible to display contacts from all sources (phone memory, SIM, applications). I tried the sources one by one, too.
