Why is the memory of Lenovo A850 mobile phone only 1 2G, not 4G?

Dear Lenovo users, this is basically the case for all Android phones, 4G, which is the total ROM capacity.

But the phone system will take up some so that the phone can be used. There is also a portion of the space reserved for users to install the software themselves. This part is where you install your favorite software during use.

The other part is used by users as a memory card, which is used to store files, **, songs, etc.

This is not a quality problem, it is a normal phenomenon. If you have any questions, it is recommended that you consult the after-sales service.

Dear Lenovo mobile phone users, hello!

We're sorry for the trouble you may have with your phone.

The ROM space of Lenovo A850 mobile phone is 4G, but due to the different calculation methods and particles (the manufacturer calculates it at 1G=1000M, but it is actually 1024M=1G to display) and a small part reserved for hiding, the actual display space will be smaller than 4G.

You can go to the "System Settings--Storage" of the mobile phone to check and confirm, it is mainly divided into two parts: "internal storage space" (occupied by the system and software installation) and "internal memory card" (can be used as U disk storage).

Please understand the above.

Junk software after root, delete slowly, don't delete many programs at once, delete them one by one, until you can't turn on the machine, restore factory settings, skip this can't be deleted, generally now the smartphone doesn't change a few bricks, it won't be good.

System file... The memory space of the phone is getting smaller and smaller the more you play.

We apologize for the inconvenience caused.

Your device ID has a total running memory of 1 GB. The capacity displayed in the menu is inconsistent with the actual capacity, mainly due to the following reasons:

1.Differences in capacity calculation methods: Hardware manufacturers usually use 1000M as 1G for calculation, while operating systems use 1024M as 1G for calculation, and different calculation methods will cause differences in actual display capacity.

2.The system hides part of the running memory: In order to ensure that the system can run normally, the mobile phone will reserve a part of the running space

a.As the cache space required for the operation of some hardware (such as CPU, camera, sensor, etc.) of the mobile phone; b.As the underlying core of the mobile phone system, the running memory required for the operation of programs and processes.

This portion of the reservation is hidden and not visible to the user.

Please refer to the above.

1. Lenovo A808T supports external SD card, and the mobile phone can support up to 32GB memory card (TF card) expansion.

2. Transflash, jointly developed by Motorola and Sandisk, was launched in 2004. It is an ultra-small card (11*15*1mm), which is about 1 4 of SD cards, which can be regarded as the smallest memory card at present. TF card can be used as SD card after SD card converter.

The adapter can be used on devices that use SD as a storage medium.

3. You can choose a memory card with a smaller capacity according to your actual situation, which will not cause the mobile phone to read the memory card slowly.

Lenovo A808T phone.

Display memory. If it is not enough, it is recommended to go to Settings - Storage to view memory usage.

1. If the internal storage space is insufficient. You can clean your phone's cache, move software to the built-in memory card, and delete unwanted software. Backup data restoration.

Factory setting. Invalid contact after-sales testing.

2. If the internal memory card space is insufficient, move the files (**, **, **, etc.) to the external memory card, computer or delete them; Remove unwanted software. Set the external memory card as the default memory and move the software to the external memory card.

RAM is running memory. ROM is body memory. You're looking at ram

The hundreds of megabytes you are talking about are not the running memory of the mobile phone, it should be 512.

We apologize for any inconvenience this may cause and affect your use.

If your device is running low on memory, you can try to adjust and improve it in the following ways:

1. Frequently or regularly use the mobile phone acceleration function of security software such as Le'an to clean up background applications, which can effectively release the running memory;

2. It is recommended to uninstall useless or infrequently used software, which can prevent the self-start of such software and occupy running memory;

3. After the application is finished, try to use the exit function of the application to completely exit to avoid the application hanging in the background and occupying the running memory;

4. It is recommended to use the built-in music security software for self-start management, limit the boot start project, avoid occupying too much running memory, due to the difference in the version of the music security, there may be differences in the menu path, take the version as an example, the path and operation steps are as follows: "music security" - "mobile phone acceleration" - "self-start management", the self-start project that needs to be restricted is manually closed, please refer to it.

The latest version of Le Safety:

Lenovo A850 mobile phone runs memory accounts for too much, the main reason is that there are many software in the Android system to obtain self-start permission, and the memory ** mechanism of the Android system is a more complex problem. For the time being, it is not possible to fundamentally prohibit the self-start of a program. If you install too much software of this kind, it will cause the phone to run and occupy too much memory.

Consider uninstalling some of the software that often self-starts and is less commonly used.

When you need to run large software that takes up memory, you can consider manually closing some programs to get more memory.

In addition, install mobile phone management software, use the software to disable the self-start of the program in the background, and automatically clean up the memory function.
