Appium 1.4.16 hangs while taking screenshot on iosdevice

I running java selenium tests on real iphone device using Appium.
My tests are running fine until it executes the command to take screenshot.
i am using the below command to take screenshot.
File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);
FileUtils.copyFile(scrFile, new File(Screenshotpath+“scrrenshot1”.jpg"));

I am not getting any error on appium log. It just hangs.


iphone 6plus - version 9.2.1
xcode - 7.2.1
Appium - 1.4.16
