Obviously, the SD card still has a lot of space, but the installation says that the memory is insuff

Now there are two kinds of mobile phone memory: RAM dynamic memory, commonly known as running memory, which is the same as the memory in the computer; ROM used to be static memory, and with the development of technology, ROM now usually refers to non-volatile memory, or in other words, they can still hold data when the system is out of power.

Also known as mobile phone memory, it is used to store the mobile phone system and some user data (including the programs installed by the user), and the role is basically the same as the hard disk, but the hard disk is definitely not a ROM.

Smartphones are a microcosm of a computer, and the phenomenon of insufficient memory is often seen, and there are two situations of insufficient memory.

1. The application is out of memory.

Most smartphones do not have high memory If you use several software at the same time, it will lead to such a phenomenon The file will not open and close at the light The phone will restart at the heavy Solution Clear the cache Close the software you don't need Don't open too many background programs Standby mode will also affect the memory The memory is the highest when the phone is turned on The longer the time after booting up, the memory of the phone will slowly drop But it will stop at a certain time.

2. Insufficient storage memory.

The C drive of the mobile phone is not high, too many installers in the C drive will cause the phone to slow down, just like the computer, the processing method will be uninstalled in the C drive, and the machine can be used when necessary.

Is it an Android machine?

The installed program is the default on the phone, it may be that the storage space of the phone is very small, you can try to transfer the phone's application to the SD card.

Memory and SD card are not the same concept.

1. SD card.

If you have enough memory but can't store it, please remove the SD card and reinsert it.

2. If it is invalid, put this SD card into other hidden worlds to observe whether it can be used normally, and rule out whether it is an SD card.

3. If it can be used normally in other mobile phones, please back up the data in the SD card and try to format the SD card (Note: If you are using a computer for formatting, please select Format-File System after the right mouse button.

4. If it doesn't work, try to update the system version of the mobile phone: please go to Settings - About the phone (about the device) - Software update (system update) - Update (please back up the data in the device before upgrading).

5. Replace other memory cards.

Try. 6. If the problem still exists, it is recommended that you bring the purchase invoice, repair card and machine to the service center of the brand to carry the machine for inspection.
