iPhone update can completely paralyze cellular reception

When Apple released a major iPhone update to iOS 14.7.1 in late July, one thing was certain. Download it quickly, because it fixes a security vulnerability that had already been exploited. But now there are problems!

Our text about iOS 14.7.1 at the time started as follows:

“It’s nothing new that updates run the risk of catching new bugs. Before, of course, you never know. In the meantime, however, we can say that the advantages of a new version almost always outweigh the disadvantages. Still, after every major iPhone update, like the most recent one to iOS 14.7, you should be on the lookout for patches and fixes soon after.”

And that’s exactly how we could have started this text. Because although iOS 14.7.1 eliminated a serious security hole, it apparently also brought new mischief to iPhones, as users complain. Only this time, there is no solution yet.

iOS 14.7.1 can lead to problems with cellular reception

As a necessary security update, users came not around iOS 14.7.1. However, as the renowned site 9to5mac.com from the USA now reported, many users spoke out in forums and on social media. According to the report, they lost any connection to the mobile network after the update. Even restarting the device and reinserting the SIM card did not help.

Apple itself has already set up a support page for the problem. Those who are affected should follow the steps there. But even that is said to have not helped many users

Currently, there is still no patch for the problem. On the contrary, the just released beta version 6 of iOS 15 is said to be able to cause the same problems, according to the website Softpedia News.

Affected users can only hope for a quick fix from Apple. Find out why iOS 14.7.1 is still important in the following two paragraphs.

Serious security vulnerability eliminated

With iOS 14.7.1, Apple patches the security vulnerability CVE-2021-30807, which allows attackers to inject malware into third-party iPhones. According to the journalistic security portal Security Week, this could already have been “actively exploited”. According to this, it is a “zero-day security vulnerability”. This means that it was only discovered when the first attack had already taken place. In contrast, other gaps are discovered in advance, even before hackers can exploit them. It is already the 13th zero-day vulnerability that Apple has had to close in 2021. Anonymous sources have reported the vulnerability CVE-2021-30807 to Apple.

Not only iPhone users are affected, by the way. Mac owners should also update. macOS Big Sur 11.5.1 eliminates the gap on Apple’s computers.

iOS 14.7.1 fixes iPhone unlocking bug

With iOS 14.7, Apple introduced the option to unlock iPhones with the Apple Watch. This was supposed to provide a remedy if FaceID did not work due to mouth-to-nose coverage. However, the function was apparently not completely bug-free. Problems occurred with certain iPhone models. iOS 14.7.1 now eliminates this bug.
