I Think i've done it! Apple has a new feature of being able to delete default apps so let me try to explain my strategy
1. create a folder (or use an existing one) and place any unwanted apps inside, like game center
2. tap and hold on an app until they all start to jiggle
3. Press and hold game center until youre able to freely move it and then drag it to the right so it's put onto the second (or next available empty) page of the folder. Release game center but leave it jiggling
4. Press and hold the game center app again so you can freely move it and then drag it to the right again until a third (or next next available empty) page but do not release!
5. While game center is being suspended by one finger, use another to tap the home screen button and the app is deleted. Repeat for all undesirable apps
there's a video (i think by buzzfeed) if i wasnt clear enough, but there is a catch. Some apps will stay gone with this method and some will come back from the dead. In fact, game center might still be activated so what you're going to need to do is restart your device and do these steps over. After the second time, the app should be gone AND disabled. Best of wishes 🙂
Disclaimer: i read through this post and Idespairofusernames seemed to have a good method. I had already tried the delete method once and it failed to remove game center after i restarted my device so i logged myself out of game center and then got myself locked out by Idespairofusernames' method, and then i tried the delete method a second time and game center no longer popped up on games, so idk if that might play a part as well. I advise you restart your device after the second run through of the delete method to see if my idea works. If not, get yourself locked out by Idespair's method and then the delete method
