Why do I say: insufficient storage space as soon as I open the message? But there is a lot of space on the mobile phone and SIM card. ...

First, the theme of installing a third-party mobile phone will occupy the memory of the mobile phone, but it is not much. If you bring your own icon, you will certainly take up more. The most economical way is to use the theme that comes with the mobile phone as much as possible, but some third-party themes save more memory than their own. I don't understand this phenomenon for the time being . .

Second, address books, short messages, communication records, business cards and photo programs will stay in the background, and they can't quit completely automatically after closing. They can be closed with the help of security housekeeper and 360 security guards, which can save transportation and storage and can be recalled when used. Personally, I think the reopening after closing is a little delayed, but it has no big impact. ...

Third, after a period of time, the storage of mobile phones has been declining. This seems to be a common problem of Saipan system. There is no better way for individuals to restart their mobile phones regularly for the time being. ...

The above problems will lead to the reason why the mobile phone prompts the lack of memory, so let's take a look at the solution:

1. There are too many open programs and insufficient memory.

Solution: Close some impractical programs and free up memory. After all, there are not many mobile phones, and Saipan mobile phones are generally 70+, and the boot is 60+. It is recommended not to open too many random startup items, generally no more than three, which will affect the speed.

2. There are not many programs open on the mobile phone, but it always prompts that the memory is insufficient. Please turn off the prompts for some applications, so that you can't delete programs and setup packages.

Solution:

(1) theoretically, Symbian S60V3 mobile phone can install unlimited software, and the larger the installation space, the better, but in fact there is an upper limit, the upper limit is 85 installation points, and some programs have more than one installation point. If there are too many, this will happen. It is suggested to delete some uncommon software or themes, which can also improve the speed of mobile phones. ...

② It may be related to junk files that occupy memory, such as installation records. It is recommended to install system cleaning software and clean it regularly, such as 360 mobile guards and security butlers. This kind of software is stupid when it is cleaned, so it can be handled automatically without management. ...

③ There are also some things caused by software conflicts. Two softwares with the same function will rob each other of resources, resulting in low running memory of the mobile phone. ...

(4) Don't install too many themes, try to copy them, because each theme will have installation information. If you have a host who likes to change the theme frequently, you can refer to the following methods.

Specific methods: firstly, install the required theme, and then copy the whole folder corresponding to this theme to other directories under the E: \ private \1020714 \ import \ folder for later use. Then, you can delete this theme in the program management, and now cut the theme folder you just copied back to the previous location-e:. Under the folder10207165438 \ import \, there will be this theme in the theme settings now, and there is no installation information in the program management. When you want to delete a theme, just delete the corresponding folder under the import.

⑤ Try not to install software that takes up too much memory. After all, our mobile phone is not a computer, so we should think about it. Moreover, the speed of running large files will not be too fast, which will affect the level of mobile phones. ...

3. Online or SMS photography is out of memory.

Solution: Clear short messages and sent messages, and try to save files on the memory card.

Here is a comprehensive explanation! There are two reasons why the mobile phone prompts "insufficient memory". One is to open too many programs at the same time, resulting in exhausted storage; Second, threads are exhausted (in S60 system, there are two limiting factors for opening more programs: memory and threads).

As we all know, every running program has at least one thread, and the number of threads in S60 system is limited. Take Nokia 5700 as an example, the maximum number of threads is 266. When the number of mobile phone threads reaches the upper limit, even if the mobile phone still has memory, the mobile phone will still prompt "insufficient memory" when opening a new program.

Under normal circumstances, the possibility that the number of mobile phone threads exceeds the upper limit is very small, but if the SIM card is in poor contact or the mobile phone is abnormal, the probability will be greatly increased. When the SIM card is used for a long time, the metal surface will be oxidized, resulting in frequent SIM card verification information such as "I can easily go to Shenzhou". Every time the verification information system appears, a SATUI.exe thread will be opened in the background, and n identical threads will appear after n times, until the system prompts "insufficient memory" after the thread reaches the upper limit.

Solution:

1. Wipe the contact pins of the SIM card with an eraser. Stick a piece of paper on the back of the SIM card, so that the antenna of the SIM card slot of the mobile phone can better contact the antenna of the SIM card. If not, you have to change your SIM card in the business hall.

2. Use Task Manager to check whether the memory capacity of the mobile phone is left. If so, look at the number of threads. If the number of threads is 200+, a program is abnormal. (There are usually many threads with the same name) The abnormal number of threads is usually caused by SIM cards. Pay more attention to the number of threads in SATUI.exe, and you will usually see more than 100 such threads. These threads belong to system threads and cannot be closed. The solution has been mentioned above.

Again, mobile phone memory is not equal to mobile phone storage, it depends on D disk!

The last one: the method to solve the problem that N73 playlist can't be played in order.

Set the third-party software as the default program for mobile phones.
