Answer 1

Use PhoneNumberUtils.compare(a, b) to filter out duplicated numbers

val contacts = ArrayList()
val uniqueMobilePhones = ArrayList()
                while (cursorPhones.moveToNext()) {
                    val displayName = cursorPhones.getString(cursorPhones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))
                    val number = cursorPhones.getString(cursorPhones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))
                    val convertedNumber = convert(telman, number)
                    var duplicate = false
                    uniqueMobilePhones.forEach { addedNumber ->
                        if (PhoneNumberUtils.compare(addedNumber, number)) {
                            duplicate = true
                        }
                    }

                    if (!duplicate) {
                        uniqueMobilePhones.add(number)
                        contacts.add(MyContact(displayName, number, convertedNumber.replace(Regex("[ -+()]"), "")))
                    }
                }
