"Shen Jing" [Tutorial] [A brief summary of the care and maintenance experience of S40 mobile phone]

First, it's clear that since the S40 is not a smartphone, it doesn't require antivirus software or system cleaning and optimization tools. Many users are still looking for antivirus software and phone optimization apps—stop it. Even if there are viruses, they're spread via USB drives—just get them on your computer and deal with them. But for boot speed and file read speed, you still need to pay attention to a lot. Let's start by organizing JAR files. Take the S60 third-generation PC as an example: after Fetion's run, it generates a 4.7MB junk file on the C drive, along with various browser caches, often hundreds of KB of junk files, so regular cleaning is necessary. In contrast, the S40 only supports JAVA extensions, making it compact and convenient to run, and most rarely leave much trace. Take JAR games as an example: after running and saving, a game generates files with the RMS extension, and the prefix matches the JAR game filename. So a 250K game will eventually become 300K after playing. But looking at the details, the file size is still 250K. Open a folder; the more content it contains, the slower the speed. Especially JAR files—for non-smartphones, this is the highest level of external program files. Piling a bunch of JAR files together will definitely slow down speed. A simple solution is to create a separate folder for each JAR program and transfer the JAR files to your phone. For engine oil with dozens of games stored in one directory on your phone, try connecting to a computer and see—there are hundreds of files here, and opening them on your phone takes several seconds. Proper classification can have a noticeable effect. Also, use common tools like UCWEB and try to store them on your phone's storage. Reading the memory card every time consumes power and is slow. Next, let's talk about organizing other files. Just like on computers, phone storage and storage cards need to be properly categorized and reasonably allocated. For example, in JAR, you can put a main folder, then create subfolders as mentioned earlier, separate music folders, and novels into one folder—how much cleaner it is! The 5310's RAM is 2MB, which is fixed. It's normal for some games to lag or experience memory overflow, since they're very small, and there's no way to fix that. Keep in mind, on smartphones, sometimes a JAR game can use nearly 10MB of RAM, so memory overflow on the 5310 is quite normal. We don't need to be too fancy, just keep things neat and organized. Searching for messy files is really inconvenient. Also, pay attention to the remaining space on the phone's system drive. Many lazy people find their phones running slowly, crashing frequently, and booting up like a snail—usually because of this. The system drive contains text messages, memos, built-in ringtone themes, and if you don't organize files in time, the remaining space is just a few MB, and then the crash occurs. Some people ask, what does the C drive have to do with running and booting speed? I'm not an expert, so I can't explain.It's like how you can't hold too much on a computer's C drive—if it gets packed with files, it gets very laggy. If you try out the Nokia 5000, you'll see—it doesn't support memory cards, apparently only 8MB of phone storage and 1MB of RAM. As soon as you buy it, you can clearly feel that opening menus, viewing files, and messaging are very slow. A friend < not very good at gaming > kept MP3s and games on the phone's storage card, but the system crashed frequently. I just transferred them to the memory card and it was fixed. The exact reason is something experts can figure out. Except for SMS and a couple of commonly used apps, delete everything else. Delete everything, not a single one, including the built-in software, like QQ, which almost all have terrible reputations. Songs and unused software are all transferred to the memory card. Also, promptly delete SMS messages from your inbox and outbox; loading on your phone is very slow. Use the regular PC suite for backup, then perform a complete backup—leave nothing behind. No computer is fine; the phone's built-in backup function can also back up your messages. This way, it's easy to leave just over 20MB of stored space on your phone. Then, back up promptly. If your phone occasionally has issues, just reset it to factory settings. Don't be stingy—just choose Restore All and Delete Everything. So, backing up your messages and contacts is the most important. For example, if your phone is freezing or can't delete anything, many problems are often solved with a factory reset. Read the manual carefully. I won't go into how to back up—both the phone's built-in features and the PC suite are fine. Finally, hardware maintenance. Phones are precision electronic devices, so protect them carefully to prevent dust and water ingress. It's recommended to use silicone covers to protect the casing. Although it loses its original style, it effectively prevents dust and scratches on the casing. Also, the feel is quite good. When reading novels, pay attention to the buttons. ANYVIEW allows custom shortcuts, so don't overpress some buttons and damage them. Also, connect the memory card to a computer periodically to check, fix, and defragment. Just right-click with the mouse—don't be stingy. Defragmentation is very practical. There are many issues with computer hard drives and removable disks, and defragmentation is often more useful than any system optimization.
