Sometimes you may find that you’ve over-customized your Home Screen layout on your iPhone, iPad, or iPod touch and want to get a fresh start, or perhaps you’ve let your kids play with your device, and are having a hard time finding your apps any more.
The good news is that iOS offers a very simple way to return to a default, flat Home Screen layout so you can start from a known position and then re-organize again from there.
Simply go into your iOS Settings app and choose General, Reset and select the option to “Reset Home Screen Layout.” You’ll be asked to confirm, after which all of the built-in apps will return to their default positions on the first page with all of your third-party apps organized alphabetically on subsequent pages.
