Bug solved? Apple closes iOS 15.1.1 verification, no regrets after upgrading

On December 21, Apple launched the official version of iOS 15.2 last week. As usual, Apple closed the iOS 15.1.1 verification channel today. Users who have upgraded the system will not be able to downgrade the system.

This is Apple's traditional operation. After a period of time, the new system will close the verification channel of the old system and prohibit users from downgrading the system. In fact, it is not just Apple, but also Android phone manufacturers. Most of them do not allow users to downgrade the system.

Netizens have given different opinions on why mobile phone manufacturers do not allow system downgrades. Apple's own statement is that system updates include bug fixes, and in order to ensure the safety of users' devices, system downgrades are prohibited. At the same time, all devices use the same system, so Apps do not need to spend time improving software compatibility during development, and the size and operating efficiency of the software can be improved to a certain extent.

However, the system cannot be downgraded. When a bug appears in the new system, users can only endure it silently until the next version is updated to fix the bug. Fortunately, iOS and Android are very mature now, and generally no malicious bugs will appear. Even if there are some problems, they will not particularly affect the user experience. If a malicious bug does appear, the mobile phone manufacturer will usually fix it in the shortest possible time.

Of course, ordinary people will not feel anything about these so-called system vulnerabilities. Most iPhone users around Xiao Lei will update to the latest system version, but there is also an exception. A friend who uses iPhone 11 still uses iOS 14.3. The reason why he does not update the system is very simple. He is too lazy to update it and feels that there is no difference in daily use.

Take iOS 15.2 for example. The official log shows that the new system mainly fixes some bugs and adds functions such as digital heritage and App privacy report. After Xiao Lei upgraded the system, he never experienced these functions. He had used iOS 15.1.1 before and had no idea what the bugs were.

Finally, let's talk about whether or not to update the system as soon as possible. There is nothing wrong with updating the new system as soon as it is launched. Even if there are bugs, it doesn't matter much. If you feel uneasy, you can wait for others to update and observe the reputation. In fact, whether to update as soon as possible does not make a big difference. After all, it is really not easy to experience how the new system is better than the old system, unless the version gap is very large.
