Upgrading and jailbreaking are the two main causes of system chaos. Upgrading refers to updating the system to a newer version, while jailbreaking refers to bypassing system restrictions to gain higher privileges. Both actions may cause problems on the system. Upgrading may cause system instability or compatibility issues. Sometimes, the new version of the system may still have some bugs, which may cause some applications to not work properly or the system to run slowly. In addition, the upgrade may cause some old programs or devices to be incompatible with the new system, which requires some additional operations to solve the problem. Jailbreaking is an unofficial operation that bypasses system restrictions and allows users to customize system settings or install applications that are not officially certified. However, there are also some potential risks associated with jailbreaking. First, jailbreaking may make the system unstable. Since jailbreaking will modify the core files of the system, this may cause system errors or crashes. Secondly, jailbreaking also increases the risk of the system being attacked by malware. Because after jailbreaking, the security of the system may be reduced, making it easier for hackers to exploit system vulnerabilities to attack. To sum up, both upgrading and jailbreaking may cause system problems. Therefore, before performing these operations, we should carefully consider and understand the possible risks, and decide whether to upgrade or jailbreak based on our own needs.

Upgrading and jailbreaking may cause the iPhone system to function incorrectly, resulting in display errors on the phone screen.

It is a system problem and can be repaired with the help of third-party iOS system repair tools, such as Apple mobile phone repair tools.

4. Software conflicts

Frequently installing various software through the App Store or browser, or running multiple software to switch between each other leads to software conflicts, which in turn leads to Faults such as black screen and flickering screen occur.

It is a software problem. You can try to force restart or perform iOS system repair, such as Apple mobile phone repair tool.

Insufficient mobile phone storage space is a common problem, which can cause various inconveniences such as slow phone operation and application crashes. If you encounter this problem, here are some solutions: 1. Delete unnecessary apps: Go through your app list to find those you rarely use or no longer need, then delete them. This frees up some storage space. 2. Clean cache files: Many applications generate cache files during use, and these files take up a lot of storage space. You can find the app list in settings and select each app to clear cache. 3. Move apps to SD card: If your phone supports SD card extended storage, you can move some apps to the SD card. This frees up internal storage space on your phone. 4. Use cloud storage: Upload some personal files such as photos, videos, and documents to cloud storage services, such as Google Drive, Dropbox, etc. This frees up storage space on your phone and allows the files to be accessed from the cloud at any time. 5. Clean your phone regularly: Clean up useless files on your phone regularly, such as temporary files, downloaded files, etc. You can use a phone cleaning app or delete these files manually. I hope the above methods can help you solve the problem of insufficient storage space on your phone. Remember to clean your phone regularly and maintain enough storage space to ensure the normal operation of your phone.

When the memory of an Apple phone is too full, such as more than 80%, it will not only affect the running speed of the phone, but may even cause a black screen or a stuck screen.

So the screen is black and flickering, which may also be caused by insufficient memory. It is a hardware problem, but it can be solved by clearing the memory in time, or by repairing the iOS system, such as the Apple mobile phone repair tool.

System version incompatibility means that the system version does not match the application or software version, resulting in inability to run properly or errors. When encountering an incompatible system version, we can try the following solutions: 1. Update application or software versions: Usually, developers will update applications or software in a timely manner to adapt to the latest system version. We can try to update the application or software to see if there is an updated version that solves the incompatibility of the system version. 2. Check the system version: Make sure the system version is the latest. Sometimes, system version upgrades may fix some compatibility issues. 3. Seek developer support: If none of the above methods work, we can contact the developer of the application or software, report the problem of system version incompatibility to them, and seek their support and solutions. In general, system version incompatibility is a common problem, but it can usually be solved by updating the application or software version or contacting the developer.

Upgrading the system may bring some brand new features, which is an exciting thing for users. However, we must also be aware that upgrading the system may also cause new problems, such as new BUGs. Nevertheless, we can still ensure the normal operation of the system by fixing these problems in time.
