In my application i have One EditText. I test my application in Google Nexus, Lenovo and Samsung Devices. Other than Samsung Device When i type wrong word it shows with an red underline. But in Samsung device it is not working. I didn't do anything to enable it on those devices. But Samsung it is not working. And i saw option in Setting page to enable/disable spell checker. But in Samsung i didn't see that setting.
How can i enable spell checker in Samsung Tablets?
My samsung Android Version 4.1.1.
Note: I need enable spell checker programmatically.

My setting screen looks like 
My layout EditText Code:
<EditText
android:id="@+id/DwEdit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="9"
android:ems="10"
android:gravity="top"
android:imeOptions="flagNoExtractUi"
android:minLines="7"
android:scrollHorizontally="false"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbarStyle="insideInset"
android:scrollbars="vertical"
android:overScrollMode="always"
android:inputType="textCapSentences">
<requestFocus /></EditText>
Open android setting menu then languages & input then check spelling indicator [x].
I think android provides a Spell Check service by default. Assuming that you didn't look for it in the developer website, here goes the link,
developer site
Also it looks like the examples are available with the sdk package itself.
