OnTouchEvent detect click not working on my Asus Zenfone

Question

I use the onTouchEvent method to be able to have a drag&drop event and a click event. I test the result on my Nexus 7 (2012), it's working really great but on my smarphone a Asus Zenfone, it's not and I can't see why, here is my code :

button.setOnTouchListener(new View.OnTouchListener() {
    private float startX, startY;
    private long startClickTime;

    @Override
    public boolean onTouch(final View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                startX = event.getX();
                startY = event.getY();
                startClickTime = Calendar.getInstance().getTimeInMillis();
                break;

            case MotionEvent.ACTION_MOVE:
                if (v instanceof Button) {
                    Button button = ((Button) v);
                    if (button.getText().length() == 0) return true;

                    ClipData clipData = ClipData.newPlainText("", "");
                    DragShadowBuilder shadowBuilder = new DragShadowBuilder(v, false, scale);
                    v.startDrag(clipData, shadowBuilder, v, 0);

                    DataHolder.getInstance().setCurrentText(button.getText().toString());
                    button.setText("");
                }
                return true;

            case MotionEvent.ACTION_UP:
                float endX = event.getX();
                float endY = event.getY();
                long clickDuration = Calendar.getInstance().getTimeInMillis() - startClickTime;

                if (isAClick(startX, endX, startY, endY) && clickDuration < CLICK_DURATION) {
                    v.performClick();
                }
                return true;
        }
        return false;
    }
});

Did someone see why my click is not triggered ?

Edit : the screenshot

Answer 1

I finally succeed to make my code working. I just added in the Action Move if the detection of a click, if it's not and only if it's not I begin a drag. That's it.
