How do I access the new Oculus Browser in the Samsung Gear VR?
Indeed, the new Oculus Browser is out, however no clear documentation has been given from Samsung support website, fortunately a few workarounds are available:

Possible fixes for launching Oculus Browser:

1. Uninstalling and re installing the software.

Users have suggested to use the following order when uninstalling: (Gear VR service, Updates Gear setup, Gear VR video, Oculus, Oculus home and Oculus system activities) 

After that reinstalling the software to make sure all latest updates are received.

Some instructions have been described here: Samsung Internet


Search and install Samsung Internet browser from the Oculus Gear VR Store
launch the Samsung internet browser from your GearVR Library
Navigate to a WebVR-compatible site
Accept the option to enable WebVR.


2. 3rd party apps 

You can try third party apps like Launch Oculus browser 1.01 developed by muchenmusik.
The authour claims it is capable of launching the new Oculus Browser on GearVR compatible phones

3. Tweaking the hardware setup

Some users described here: How to fix Gear VR not launching when phone is plugged in? have complained of related issues with the browser especially when plugging in,
and a simple fix was to remove the connector on the GearVR and then putting it back. Check if it works.

Hope this helps
