2. Waiting for the system to preliminarily scan the junk files in the mobile phone can release some memory.
3. In the mobile phone housekeeper, select "mobile phone slimming"
4. Wait for the application to scan the files in the phone. After scanning, you can selectively delete some files with different sizes.
Why are Android mobile phone card 2 1 and Android system code open source?
As we all know, the biggest advantage of Android system is open source. The system source code can be used, modified and distributed by the public, allowing any mobile terminal manufacturer and developer to join the Android alliance. However, open source also has disadvantages, that is, the application quality is uneven and the standards are chaotic.
Open source has greatly lowered the threshold for Android developers. An application with simple functions is likely to occupy 200 MB of RAM due to the rough code quality. If the mobile phone only has 2GB of storage, the congestion will become particularly obvious.
When we are operating an Android phone, sometimes we open a browser software, and several related apps will automatically wake up in the background, even if nothing happens in the Android native system. After all, behind this mechanism is an inter-application interest chain. For the domestic application market, Google is beyond its reach. A large number of programs will inevitably slow down the running speed of the mobile phone, and the mobile phone will not run smoothly.
2, the system precipitation garbage
Wechat is the most commonly used communication software today. The Android version of the installation package is 30MB in size, but if you look at this application after half a year, its memory occupation can reach 500MB or even more. This situation can be seen everywhere in video software, especially in some social and music/video applications. Over the years, when the mobile phone storage is almost full of applications, the system will definitely run slower and slower.
3. The system version cannot be upgraded.
According to the report, at the end of last year, the market share of Android5.0 and above (Android 5. 1 and Android 6.0) only accounted for 26% of all Android camps. In other words, two-thirds of users are still in Android 4. X era. Why emphasize this watershed? Starting with Android5.0, the Android 5.0 system was completely converted from Dalvik to ART. Before the system conversion, the virtual machine Dalvik was dynamically compiled and executed by an interpreter named JIT(Just-in-time) during the running of the application, which greatly slowed down the running efficiency of the system. In contrast, ART mode is to precompile the application when the user installs it, and advance the compilation action to the application installation when the program runs. After omitting the process of explaining the code, the application will run more efficiently.
The fundamental reason for the delay in completing this update is that many manufacturers rarely push the system upgrade after the mobile phone is sold, and a large number of consumers do not have the habit of updating the mobile phone system. Many mobile phone systems are stuck in Android4.4, but more and more new applications are built to adapt to higher systems, so it is inevitable that mobile phones will get stuck.
I'm stuck with what the user needs to do.
How to solve the problem that the mobile phone is getting more and more stuck? First, you need to have a mobile phone that can ensure that the system is updated regularly; On this basis, the mobile phone memory is cleaned regularly, and the fragments and some cached information are cleaned. Further operations will also use the firewall or third-party self-startup management software that comes with the system to block some self-startup applications according to usage habits.
Of course, it is not difficult to find that with the accumulation of time, it is inevitable that the mobile phone will be stuck at this stage. What users themselves, even mobile phone manufacturers, can do is to delay the time of this jam. We can only hope that those technical developers will develop mobile phones that will not be stuck as soon as possible.
