Apple saw fit to release a new beta of iOS 14.7 to developers for testing purposes yesterday. While the new beta is more stable than the previous one, the company has also fixed a bug that was oriented towards your iPhone's Wi-Fi. Last month, it was discovered that connecting to Wi-Fi with a certain name can disable your iPhone permanently. Thankfully, the company has now fixed the Wi-Fi bug in iOS 14.7 beta.

As mentioned earlier, connecting your iPhone to a specific WiFi network with the name "%p%s%s%s%s%n" can wreck the device's ability to connect. Now, it was discovered by the YouTuber Zollotech that Apple has quietly fixed the WiFi bug in the latest iOS 14,7 beta. What this means is that the fix will be coming with the rollout of the update to everyone soon.
