Usually, it’s ok to wait until Apple pushes through iOS and iPadOS updates. However, iOS 14.4 and iPadOS 14.4, which were just released, should be installed right away because they fix three security bugs that were found by hackers.
The vulnerabilities allow remote attacks on your device to run malicious code and give hackers privileges to access personal information on your device. And because the hackers found the bugs before Apple did, they’ve had time to figure out how to exploit them.
Now is a good time to update your software – go to Settings > General > Software Update.
