On each Android phone there is a folder for downloads in which everything you download from the Internet is stored. Such a folder sometimes can take a lot of space, because whenever we need to download any media or apk files, we simply load them, install, and then forget about them. Thus, in this folder, many files that slow down the work of our phone can be accumulated.

How to see the available amount of free memory on Android?

When buying a phone or when installing an application, it is important to check the available amount of free phone memory. We give step-by-step instructions on how to do it. To begin with, we note that you distinguish operational and built-in phone memory. Operational. necessary to process the processes of the operating system, to maintain the operation of running applications and T.P. Built-in is designed to store various files (video, photo, applications, etc.P.). Accordingly, there are several ways to learn the volume of free memory of the phone, both operational and built-in.

The easiest way to get information as follows. Open the “Settings”.

In the root menu, looking for the “Memory” section

We have information about the number of available and promoted RAM. Immediately you can find out the details of its use by different applications.

Information about free location on the external drive can be viewed in the “Setup” section. “Storage and USB drives”

This section provides information on the free container of the phone and the volume that is busy.

You can also check the memory status using applications.

The most popular is the Antutu Benchmark application (download).

You will appear a list of items that can be tested on the phone. As you can see, it is possible not only to test the performance of the device, but also graphics performance, write / read speed with an SD card and. Select the items you need, click the Start Test button.

Time that will be required to test depends on the number of selected items and from the volume of the RAM. When the test is completed, you will receive detailed information about the device.

At the presented screenshot, the total amount of RAM is 2825 MB, and the number of used. 319 MB. Accordingly, the total volume of the built-in. 24.59 GB, and the number of uses used. 7.83 GB.

In conclusion, we note that information about the total volume of operational and internal memory (the possible maximum volume of embedded SD cards) is indicated in the instructions for the phone. The total amount of RAM always remains unchanged. Users often encounter messages about its lack on the device. For the reasons and eliminate such errors, see other sections.

Causes of memory fill

For the volume of free space, many moments affect. Especially tangible problem with long use of the gadget.


The owner of modern phones should be ready for the fact that not all memory is available to him. About 2-3 GBs need a system for normal stable operation of the system.

If the phone reports a lack of free space, while the memory card is empty, the filling could occur at the following points.

  • The system for work occupies a place for the required components.
  • After installation, user programs occupy a place and highlight free space for their working and temporary files.
  • Very often when removing applications, the cache of this program remains. It takes a large volume, but it is not visible.
  • If you do not set up the phone when purchasing a phone, then automatically the video and photo-information shown by the user will be saved in the internal memory. Better for such purposes to use a removable flash drive.
  • If viruses appeared on the phone, then the likelihood is that they occupied precious space.

When installing new programs, the phone gives a message about the lack of space and the need to remove excess. This problem becomes the moment when there is nothing to delete, and there is not enough space in mind. Need to urgently look for a decision.

How to quickly clear the Android memory (the easiest way)

An important point to be borne in mind: If your device is installed android 6 or a newer version, and there is also a memory card formatted as an internal storage, then when you retrieved or malfunction, you will always receive a message that not enough memory ( With any actions, even when creating a screenshot), until you install this memory card again or do not go to the notification that it is retrieved and not click “Forget Device” (consider that after this action you will no longer be able to read the data From this memory card).

As a rule, for a novice user who first encountered an error “not enough place in the device’s memory” when installing Android applications, the simplest and often successful option will be easy to clean the cache applications that sometimes can take the precious gigabytes of internal memory.

In order to clear the cache, go to the settings. “Storage and USB drives”, after that at the bottom of the screen, pay attention to the Casha data item.

In my case, it is almost 2 GB. Click on this item and agree to clean the cache. After cleaning, try downloading your application again.

You can clear the cache of individual applications, for example, Google Chrome cache (or another browser), and Google photos are taken by hundreds of megabytes. Also, if the error is “not enough memory” caused by updating a specific application, you should try to clear the cache and the data for it.

To clean, go to the settings. applications, you need to select the application, click on the “Storage” (for Android 5 and above), after which click the “Clear Cash” button (if the problem occurs when updating this application. then use also “Clear data “).

By the way, note that the size occupied in the application list displays smaller values ​​than the amount of memory that the application and its data actually occupy on the device.

What is external storage and where is

Now consider what EXTERNAL STORAGE in Android. This is an external storage where custom data are saved, which is easy to find on the phone. The Storage folder will be located in Android / Data, and in this catalog numerous subfolders with application names (the location of the external memory determines the OS, but not a user).

Cleaning the cache and exemption place in the Android OS storage

There may be various files, such as music, photos, video, and other content, accessible to the user and applications. That is, the External Storage location can be in any place in the phone‘s memory or on a removable media, and under the external storage is implied not only the SD card, but also part of the built-in Android device memory (the difference from the internal. in protected).

Thus, there are two types of external drives:

  • PRIMARY EXTERNAL STORAGE. Built-in public access storage, to work with which you can use the USB connection of the smartphone to the computer or laptop.
  • Secondary EXTERNAL STORAGE. Removable memory, for example, SD card.

External external container management is carried out through the available operating system tools or the installed file manager, you can use third-party software. Any manipulation with files are available to the user, you can rename them, copy, transmit, delete, etc. D. In this case, deleting some data may affect the functioning of individual programs installed on the device, so it is better to check the purpose of the element before.

The overall external storage to save data, common to different applications lies in the root of the external section (next to the Android folder), for example, DCIM folder for photographs from a smartphone camera. These files will remain in place if you deleted the application, but if necessary, you can perform steps to remove them manually.

The external content used to save files is supported by each Android device, it differs in volume depending on the device model, and this information is specified in the characteristics.

And internal, and external storage performs the task of storing temporary or permanent data, while the sections are characterized by the level of access to information.
