[Q] mobile data does not work at first try topic

Hi,

I have the exynos version of the note 4.
Has anyone encountered this?

1. I enable mobile data
2. Notification bar shows I'm connected to 4G
3. In browser, I'm unable to connect

Disabling mobile data and enabling it again does not work, too.

So i tried to enable Airplane mode, and then disable it. It would work everytime i do this.
