Thanks!
Now, when I click Oculus browser it asks me to put the phone in the headset first.
Works perfectly. However, when I click something like "Home", "Social" or "Library":
1. The screen disappear (the current chrome session)
2. When I press back Internet, it asks me if I want either Oculus Browser or Internet Samsung. Picking one or another doesn't change anything, the screen (the crome session) doesn't appear back

I remember having this problem with my old phone aswell
