Prison break is risky? Scrub the machine carefully

As a closed system, Apple's iOS has very strict management authority, and users can only download it from the App? Download the application in the store, this function also makes its security better guaranteed.

However, after "jailbreak", the management authority of the system was changed, and users can install third-party applications at will without Apple's audit. This not only brings convenience to users, but also greatly increases the security risks of mobile phones. It is very likely that users will accidentally download some applications with hidden Trojans or other viruses, so that hackers can easily steal users' information and bank accounts. For the sake of safety, please don't choose Prison Break.

So root may not only affect the stability of the mobile phone system, but also bring some potential security risks. Everyone should try to avoid roots.

In addition, when downloading an App, you should pay attention to choosing a formal App application market, such as App Bao. Pay attention to the relevant permissions when installing. If these permissions have nothing to do with the software itself, try not to install it.
