Any other tools, like Antivirus software? Things like cleaner apps, antivirus, VPNs all cause issues with normal things on iPhone. None are needed.


If you can't update your phone over the air, use your computer to do the update. If you have a Mac, use Finder. If you have a Windows computer, use iTunes or the newest Apple Devices for Windows.
