Validate valid phone number entry
I want to figure out invalid phone numbers entered in edittext before hitting the OTP api. Invalid phone numbers pattern may looks like these patterns [phone] / [phone] / [phone] ...and so on. Already added a check to validate invalid phone number but it didn't helps in detecting invalid patterns of phone numbers which can't exist.
private boolean isValidMobile(String phone) {
return android.util.Patterns.PHONE.matcher(phone).matches();
}

Anyone please suggest how...
