Appium Android with Androis 11

Hi, I’m using this function to check if element exist on screen (Real Device)

public boolean exist() {
    try {
        WebElement element;

            element = Android.driver.findElementByAndroidUIAutomator(locator);

            return true;

    }catch (Exception e) {
        return false;
    }

// }catch (NoSuchElementException e) {
}

In Android version that under 11 if the Element dos not exist the line :

element = Android.driver.findElementByAndroidUIAutomator(locator);

is very quick ( About 1 sec)

BUT in Android 11 if the Element dos not exist its take about 20 sec

What can i do ?

I cannot wait 20 sec ( During my tests I check hundreds of times ןכelements exist or not on the screen)

Thanks !!
