+# deviceInfo
+
+The `deviceInfo` module can be used to get and set properties about device in weex such as fullScreenHeight.The module is suggested when you create a full screen page.
+
+# API
+
+## enableFullScreenHeight
+
+Since the default screen height in weex may exclude the height of status bar on some full screen devices.`enableFullScreenHeight` can be used to make full screen pages on these devices.
+
+#### enableFullScreenHeight(callback,extend)
+
+* **@callback**, function，callback when complete.
+  * **`fullScreenHeight`**, string, the current full screen height.
+
+* **@extend**,  optional parameters，please input {}.
+
+
+#### example
+
+```javascript
+  var deviceInfo = weex.requireModule('deviceInfo')
+  var modal = weex.requireModule('modal')
+  deviceInfo.enableFullScreenHeight(
+  function (e) {
+    modal.toast({
+      message:"full screen height:" + e.fullScreenHeight,
+      duration:1,
+    });
+    
+},{});
+```

+#### enableFullScreenHeight(callback,extend)
+
+* **@callback**, function，用户操作完成后的回调
+  * **`fullScreenHeight`**, string, 全屏高度
+
+* **@extend**,  可选参数 请传入{}
