What are you using?
If your using the deo cardboard app you can set the zoom where you like it so you won't have to zoom out in every scene u watch...
In deo app I have my zoom set at -8 by default
What you do is, click on the zoom when a video is playing on the player, click on the negative to where you want it then open the camera settings and down at the bottom it will say "set as default"
But yeah. If you're cardboarding upgrading to a quest 2 would be a big upgrade for you 😉
