Regularly Update Device Operating Systems and Mobile Applications
We’ve talked about this before, and we’ll probably mention it again in the future: You need to update your devices. This is the easiest way to avoid running into any trouble. If the company that makes your device and its operating system fixes a security vulnerability, the only way for you to stay safe is to update your device.
If you’re on iPhone or iPad, that’s as easy as going to Settings > General > Software Update. If there’s an update available, it will show up there, and you can start installing it in a single tap. Your device will do the rest.
