Not Updating It
Keeping your iPhone’s software up-to-date is one of the best things you can do to keep it running smoothly and securely. Not installing updates can lead to buggy performance or vulnerability to serious security flaws.
- Check for updates regularly. Download the latest iOS update whenever possible, as well as the latest carrier settings update.
- Switch on automatic updates. Head over to Settings > General > About > Software Update. Make sure Automatic Updates is On.
- Don’t forget about your apps. Third-party apps can suffer from bugs and security vulnerabilities, too. Make sure to keep all of your apps updated alongside iOS.
