Graphic Symbols with TextWatcher Disabled on HTC Longpress

I have 3 EditText elements and I want to switch from one field to another if there are 4 characters in the input.

I use TextWatcher for this:

getEditView(R.id.edit_code1).addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {}

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

    @Override
    public void afterTextChanged(Editable input) {
        if(input.length() == 4){
            getEditView(R.id.edit_code2).requestFocus();
        }
    }
});

The input type for EditText is "textCapCharacters"

When you make a long press on a key to get a number, for example, holding R to get 4, most devices will not add letters until the user stops holding the button and shoots after TextChanged after the letter 4 is selected. On the HTC keyboard (in In this case, HTC Desire on 2.3.5) is not. Despite the fact that the user still holds the button, R is added to EditText, and afterTextChanged is launched, and the code performs its task and puts focus on the next field.
