findElement is not working in Appium on Android

I am trying to click on display button in Settings app.
But “findElementBy..” statement is not working, Sometimes I get ‘nullpointer exception’ or ‘no such element exist’ exception and some times test passes without clicking Display button.

I have tried with different application but still the findElementBy… is not working in Win10.
But the same piece of code is working, when I run it on the same real device from my Win 7 laptop.

Project is using following jars:

1. gson-2.2.2.jar

2. java-client-4.1.2.jar

3. selenium-server-standalone-3.4.0.jar

4. Android Development Tool for Eclipse (addon)

5. Android for Maven Eclipse 1.4.0 (addon)

6. Appium Sever (ver: 1.4.13.1)

Appium Code:

@Test
public void Script1() throws Exception{

    DesiredCapabilities capabilities = new DesiredCapabilities();

    capabilities.setCapability("automationName", "UiAutomator 2");
    capabilities.setCapability("platformName", "Android");
    capabilities.setCapability("platformVersion", "6.0.1");
    capabilities.setCapability("deviceName", "Redmi 3S");
    capabilities.setCapability("appPackage", "com.android.settings");
    capabilities.setCapability("appActivity", "com.android.settings.MainSettings");

    AndroidDriver driver = new AndroidDriver(new URL("http://127.0.0.1:4723/wd/hub"), capabilities);

    Thread.sleep(5000); 
driver.findElementByAndroidUIAutomator("UiSelector().text("Display")").click();
}

}
