TextWatcher and InputFilter bug/non consistent behaviour?

Question

The basic problem

I noticed a strange behavior when I combine an InputFilter with a TextWatcher. What I basically want to do is to help the user type a MAC address. First of all I want to add a separator (":") every two character the user types. The code works as expected with my vanilla Nexus 7, but with my LG Optimus 4X HD (fair enough it has a nightly Cyanogenmod on it), but also with a stock Samsung Galaxy S4, there is a strange behavior.

The code

I added an EditText with the ID editText1 to an empty Project and Layout and added the following code to my activity (auto generated functions not copied):

public class MainActivity extends Activity {
private static final String LOG_TAG = MainActivity.class.getSimpleName();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    EditText et = (EditText) this.findViewById(R.id.editText1);

    et.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
    et.addTextChangedListener(new TestTextWatcher());
    InputFilter[] inFi = { new InputFilter.LengthFilter(17),
            new TestInputFilter() };
    et.getText().setFilters(inFi);
}

private static class TestTextWatcher implements TextWatcher {

    private static final String regExp = "..(:..){5}";
    private static final Pattern pat = Pattern.compile(regExp);

    @Override
    public void afterTextChanged(Editable s) {
        Log.d(LOG_TAG, "AFTERTEXTCHANGED: " + s.toString());
        Matcher m = pat.matcher(s);
        // if does not match regexp
        if (!m.matches() && !m.hitEnd()) {
            SpannableStringBuilder ssb = new SpannableStringBuilder(s);
            Log.d(LOG_TAG, "remove " + ssb.toString());
            for (int i = 0; i < ssb.length(); i++) {
                char c = ssb.charAt(i);
                if (c == ':') {
                    ssb.delete(i, i + 1);
                    i--; // recheck same position
                }
            }

            Log.d(LOG_TAG, "insert " + ssb.toString());
            for (int i = 2; i < ssb.length(); i = i + 3) {
                ssb.insert(i, ":");
                Log.d(LOG_TAG, "Inserting: " + i + " " + ssb.toString());
            }

            Log.d(LOG_TAG, "trunc " + ssb.toString());
            if (ssb.length() > 17) {
                ssb.delete(17, ssb.length());
            }

            Log.d(LOG_TAG, "replace " + ssb.toString());
            s.replace(0, s.length(), ssb);
        }
    }

}

private static class TestInputFilter implements InputFilter {

    @Override
    public CharSequence filter(CharSequence source, int start, int end,
            Spanned dest, int dstart, int dend) {
        Log.d(LOG_TAG, "FILTER: source: " + source.toString() + " dest: "
                + dest.toString());
        // if character is deleted do nothing
        if (end - start == 0) {
            return null;
        }
        StringBuilder sb = new StringBuilder(dest.toString());
        sb.replace(dstart, dend, source.toString().substring(start, end));
        if ((sb.length() - 2) % 3 == 0 && sb.length() < 17) {
            SpannableStringBuilder sourceAsSpannableBuilder = new SpannableStringBuilder(
                    source);
            sourceAsSpannableBuilder = (SpannableStringBuilder) sourceAsSpannableBuilder
                    .subSequence(start, end);
            sourceAsSpannableBuilder.append(":");

            Log.d(LOG_TAG, "filter, spannable " + sourceAsSpannableBuilder.toString());
            return sourceAsSpannableBuilder;
        }
        return null;
    }
}

}

The problem

I pressed mutliple buttoms to add some characters and then try to delete all characters. Log of Nexus 7 (as it should be):
