When someone sending a contact, formatPhoneNumberWithCode always insert "+" before phone number but it wrong. At least in our country, we have number without "+", instead of "+" numbers can start with "8", for example, "87172123456". Now, before this number wrong formatting adds "+" and you get "+87172123456" - completely wrong number (+8 - Japan or Korea country codes, as far as I know, but this is doesn't matter).
