Putting off Updates
If there’s one thing that we recommend you do regularly, it’s updating your phone to the latest available software. Not only will you get new features occasionally, but you’ll also be receiving bug fixes and important security updates in the process.
While you may want to wait a day or two to download a major software update, we recommend downloading and installing smaller point releases as soon as you can. Keeping your device up-to-date is one of the best things you can do for it. You can find new updates by going to Settings > General > Software Update.
