[Transfer] Let’s talk about the hidden functions of “Developer Options” in detail

Let's talk about the hidden functions of “Developer Options” in detail. By the way, if you don't have developer options on your phone, you can go to Settings - About Phone - Software Version and click on it. Then he will remind you that you have entered developer mode. If you have any questions, please message me. Starting from version 4.0, the Android system has added a new setting item "Developer Options" to the system settings, which integrates control switches for a variety of systems and applications. However, many Android users do not know what functions these complex options have. This issue will tell you in detail what impact turning on and off these options can have on your mobile phone system.
Some options are only suitable for developers and have nothing to do with ordinary users
Although in the "Developer Options", each option has some simple text descriptions, the specific functions of many settings are not explained clearly. In addition to the "debug mode" that we ordinary users will use when using synchronization tools such as Wandoujia, other functions have basically not been studied in depth. In fact, there are many practical functions hidden in the "Developer Options", which can even make your phone smoother. It depends on whether you are willing to put in the effort.
The first introduction is the two functions of "Desktop Backup Password" and "Monitoring Options". They can easily cause users to misunderstand that these two control items are options related to system security. In fact, they are not. "Desktop backup password" is the first setting item in the developer options. Starting from Android 4.0, developers can back up the entire mobile phone system through the latest SDK (Software Development Kit), and the function of this option is to set a backup password in advance. When developers back up the mobile phone system through the SDK, they need to enter the set desktop backup password before backing up. This ensures system security to the greatest extent.
Similarly, the "monitoring options" have little to do with us ordinary users. Whether it is strictly monitoring or displaying CPU and GPU usage, it is all to facilitate developers to observe the application's occupation of system resources. For us ordinary users, if these functions are checked, it is nothing more than displaying a lot of jumping numbers on the screen and controlling CPU and other usage in real time. It will not have an impact on the performance of the phone.

The desktop backup password is to ensure that the system is not easily backed up

The monitoring option is to display the hardware usage of the phone. This dense text seems a bit annoying

What exactly do Android system developers develop?
The in-depth development of the Android system is due to the discovery of root permissions. As early as 2008, after the first Android mobile phone was released, developers discovered a method to gain Android privilege control "rooting" (also known as "rootaccess"). This discovery, combined with the open source nature of Android, allows the phone's firmware to be modified at will. It is precisely because of the emergence of root permissions that some teams began to recompile and modify the Android system based on the Android source code, thereby designing more powerful third-party Rom for users to use, such as the very famous foreign CyanogenMod and domestic MIUI. These are teams that conduct in-depth development of Android.
However, the most difficult thing in Android system development is to make changes to the Android system kernel. This is a very tedious task. By adding more powerful self-made code, more functions that cannot be achieved by the native Android system are achieved. For example, the source code of CyanogenMod was written by Cyanogen (real name Steve Kondik). Later, the main screen, caller and web browser enhanced by the xda-developers community were added. Other important programs such as BusyBox were also added to make the phone more playable.
