联系人只显示数字的一部分（来自Skype，Wiers等的应用程序的124个联系人），但实际上应该有更多的联系人，他们在手机上（确认 - 进入时电话号码+7有449个数字）。
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.
You have 124 contacts saved to your phone. When you press +79, you get 449 in the dropdown. This 449 represents the number you have dialled (starting with +79) till date, from your device. Those may be the saved numbers or unsaved too. This is not a bug. Hope this satisfies you query.
Update - adding the screenshots of my Lg 5.0.1. When I search for contacts starting with 7 in Contacts tab, 250 contacts are shown.
While, when I type 7 in dialer, 396 contacts are found.
That's what happens with every phone. It's not a bug.
Touch three vertical dots at top right corner. It should let you change settings related to your contact book. Look for a setting named as - Contact Display or something similar. Make sure you have selected All Contacts
In Contacts click the 3 vertical dots on the upper right, select Filter , and then in Display contacts section select only Local, in order the device displays only your locally stored contacts (phone numbers). This holds for Sony Xperia M4 Acqua Android 6.0.1 version.
