Standalone solution for format raw phone number, if you don`t know your country and need support on pre-lollipop.

fun formatNumberCompat(rawPhone: String?, countryIso: String = ""): String {
    if (rawPhone == null) return ""

    var countryName = countryIso
    if (countryName.isBlank()) {
        countryName = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            Resources.getSystem().configuration.locales[0].country
        } else {
            Resources.getSystem().configuration.locale.country
        }
    }

    return if (Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP) {
        PhoneNumberUtils.formatNumber(rawPhone)
    } else {
        PhoneNumberUtils.formatNumber(rawPhone, countryName)
    }
}
