Ohhh..lol..it got my attention because you mentioned in it about a super awesome data speed..
Yea for an old Note 4. One thing to be aware of is the more you modify system apps , deni permission, chang receivers and delete stuff the less fluent your device will become (generally but not always). Sometimes its a good idea to go back and grant permission and test the difference.
Usually, the best way to test speeds is connected to home wifi rather than carrier data.
