You can try the free version, but this is pretty cheap for what you get. This allows you to freeze the Oculus Service app so it doesn't auto launch. And you DO NOT need Root

Next up, you need to get your signature file and make an app and install it so you can enable developer mode. This app makes it super easy and will guide you through the app creation process. It'll have you get your sig file, upload it, and you can just pick a random app that it'll repack, and it does this all on your phone
Now that you have both of those done, turn on developer mode to reduce blurriness.
Go to your device Settings -> Application manager -> Gear VR Service (usually in the "Downloaded" section but could also be in the "All" section).
Tap on "Manage storage"
Tap the "VR Service Version" number six times.
Wait for scan process to complete and you should now see the Developer Mode toggle on this screen.
ENJOY! It worked on my Tmobile Note 5, not rooted.
