enable/disable zoom in Android WebView

Question

There are some methods in WebSettings related to zoom:

• WebSettings.setSupportZoom
• WebSettings.setBuiltInZoomControls

I noticed they work differently on some devices. For example, on my Galaxy S pinch to zoom is enabled by default, but on LG P500 it is disabled (And now I don't know how to enable ONLY pinch to zoom, but hide zooming buttons).

On P500 when I call setBuiltInZoomControls(true) I get both these variants working (multitouch and buttons).

How to enable multitouch zoom and disable zooming buttons on devices such an LG P500? (Also, I know the same problems are on HTC devices)

UPDATE: Here is almost full code for the solution

if (ev.getAction() == MotionEvent.ACTION_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_1_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_2_DOWN ||
        ev.getAction() == MotionEvent.ACTION_POINTER_3_DOWN) {
    if (multiTouchZoom && !buttonsZoom) {
        if (getPointerCount(ev) > 1) {
            getSettings().setBuiltInZoomControls(true);
            getSettings().setSupportZoom(true);
        } else {
            getSettings().setBuiltInZoomControls(false);
            getSettings().setSupportZoom(false);
        }
    }
}

if (!multiTouchZoom && buttonsZoom) {
    if (getPointerCount(ev) > 1) {
        return true;
    }
}

This code is in my onTouchEvent overridden method of the WebView.

On API >= 11, you can use:

wv.getSettings().setBuiltInZoomControls(true);
wv.getSettings().setDisplayZoomControls(false);

As per the SDK:

public void setDisplayZoomControls (boolean enabled) 

Since: API Level 11

Sets whether the on screen zoom buttons are used. A combination of built in zoom controls enabled and on screen zoom controls disabled allows for pinch to zoom to work without the on screen controls
