Default E/connectivityService(501): warning, forbidden third-party APP to active mobile data

Hi Guys,

I am just trying to disable / enable 3G mobile data connection automatically, and tried several apps from play store and all of the apps were not able to control mobile data. I see the following error message when running logcat on terminal:-

E/connectivityService(501): warning, forbidden third-party APP to active mobile data connection


- I am using Gfive G9 mobile running android 4.2.1
- I can manually turn on and off 3g mobile data connection using quick launch button - no problem
- Data connection is working when it is turned on - no issue
- But i need to use third party app (like llama, or Data on-off) to control my data connection when screen off or match configured rules but none of the application seems to control data connection due to above error.
- I am not using any other app as a firewall to restrict communication with data connection.


Just wondering if anybody has came across with the issue before?
Any help please?

Thanks in advance
