[T-Mobile Samsung Galaxy S II SGH-T989] mocsab:
I was going to start a thread for this but saw you asked the question so I will just do this here

I remember that on the Note 3 the Data Toggle was misssing - and someone posted a way to add it back - you have to download Sequelite from the GOOGLE PLAY to do this - but otherwise, it is very easy to do - if I can do it - anyone can -

So I searched online and found a thread in another forum - I need to give credit to the author because I did not do anything other than copy his instructions:

The original thread came from [MENTION=3693413]jdawgg21[/MENTION]#AC in the Android Central Forum - out of respect for XDA I won't post a link but anyone doing a GOOGLE search on how to add a Data TOGGLE to NOTE 3 will find the same Link I did - from jdawgg21#AC original instructions, here are the steps you need to take to add the Data Toggle to your phone -

DISCLAIMER: This is to add the MobileData toggle to your notification panel on the T-Mobile Samsung Galaxy Note 3. It might or might not work on the other models. Your phone has to be rooted in order for this to work. I'm not responsible if you screw something up on your device by not following directions. (It works fine on the NOTE 4) And the best tip I can give you is - be sure you are in the right line when you add MobileDATA - there are several that look the same - but it must be the RIGHT ONE - I think I recall that there are two that look similar - but the 2nd one - way toward the bottom of the list - is the right one - and it has to say notification_panel_default_active_app_list exactly for it to be the right one that you need to edit.

Here are the steps I used:

1. Download the Sqlite Editor app from the playstore(costs

2.99)https://play.google.com/store/apps/d...ware.sqleditor

2. After it's download, it will ask for root permissions, click Grant and it should load the databases.

3. Go to the FILES tab

4. Click on data, then after it opens up, look for data again

5. After that happens, scroll down the list till you find com.android.providers.settings and click on it

6. Click on databases and then click on settings.db

7. After you click on settings.db, then you will see system, click on that and it should open up a long list

8. Look for notification_panel_active_app_list. It will be near to the bottom of the list. You will see notification_panel_default_active_app_list. That is not the correct one. Make sure it says notification_panel_active_app_list.

9. Click and hold it till a sub menu pops up. Click on Edit Record

10. You're going to see a list of toggles under values

11. At the end of that list, make sure there is a ; after the last word. Then enter MobileData and put ; right after it. No spaces.

12. It should look like this for example: AirplaneMode;MobileData;

13. Now click Save, Reboot the phone and when it comes back up, you should have a MobileData toggle in your notification panel in your settings

As I said I am not responsible for this but happy to share the results of my GOOGLE SEARCH with anyone intersted in adding the Data toggle to their NOTE 4 - this was originally written for the NOTE 3 - but it works fine on the NOTE 4 - as evidenced by the screen shot i attached
