Almost everyone now has a variety of mobile gadgets, one of which, most often, is a mobile phone - a smartphone. And as you use the phone, the owner is faced with a lack of internal memory of the phone or the need to expand the general memory to store photos, videos or music. So, let's figure out what the differences are between internal and external memory phone, what are the reasons for its shortage.

Phone internal memory

In addition to internal memory, many phone models have a slot for microSD or microSDHC memory cards. But some models do not have this connector and the user has to be content with internal memory, which can become an unpleasant surprise. If your phone does not have a slot for a memory card, and you like to take photographs, shoot videos in high resolution, or always have an extensive audio library with you, then at some point you may encounter a message “not enough memory” or that you need clear system memory.

The internal memory of the phone is physically a memory chip that is soldered onto system board phone.

Features of using the phone's internal memory

Some manufacturers and operating systems that are used in smartphones make it possible for their gadgets to use applications only installed in the internal memory of the phone. In addition, some programs have peculiarities - they do not work from memory cards and their installation in the internal memory of a smartphone is dictated by the requirements of the developer of this software. In some cases, such restrictions can be circumvented in various ways, however, this is not always possible.

How to clear phone memory

First of all, you can delete unnecessary photos, music, videos or unused applications. It is best to transfer the footage to a computer or other storage device, thereby freeing up internal memory for new multimedia files.

You can clear your phone's memory directly through the system menu using built-in tools.

Android phone memory

The Android operating system allows you to view the total memory of the device, internal memory available for installing applications and external memory (if any), expanded by memory cards. Manufacturers Lenovo, Samsung, HTC, Fly and others themselves determine how much of the phone’s internal memory is dedicated to installing applications and games, and how much space the user can use to record files and data.

Most often, information about the state of internal and external memory mobile phone located in the “Settings-storage-memory” or “Settings-programs-memory status” section. Various options are possible depending on the version of Android, the version of the shell and the version of translation and Russification of the device by the manufacturer. You can view the memory status of your Android phone in other ways - third-party software, for example Antutu Benchmark or System Information Tool - various system utilities that allow you to see the phone’s hardware.

How to increase phone memory

If you are lucky and your phone model is equipped with a slot for a MicroSD memory card, then you can increase the total memory of your phone by installing this card or replacing the one that is already installed. You should pay attention to the maximum memory card capacity supported by the device.

Card slot can be made in different ways and be located under the back cover or under the battery, under the plug on the side of the device.

But before rushing headlong to correct this injustice, it is worth finding out why this happens and how exactly you can clean the system.

Android File System Structure

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2015/09/faylovaya-sistema-android.png" alt="File system structure Android" width="200" height="356" srcset="" data-srcset="http://androidkak.ru/wp-content/uploads/2015/09/faylovaya-sistema-android..png 168w" sizes="(max-width: 200px) 100vw, 200px"> !} One thing worth understanding: file system Android is not nearly as versatile as, say, Windows. If on Windows your programs and media files are in the same space, then on Android each type of file has its own section.

System programs - separately, auxiliary files and music - separately. The first partition is called the system memory, while the last one is called the media partition.

Why is this necessary? First of all, to make the OS as secure as possible. If you combine these sections, it turns out that a regular media player can accidentally delete data important for the operation of another program, crash the system, or simply fill it to capacity with its files, without leaving even a byte for the necessary system programs.

Moreover, these two sections have different access levels. In the media section, the user and third-party programs can do whatever they want. To section system programs Android has no use for anything other than these programs.

Because of this order of things, sometimes a rather curious situation occurs: the media section has several gigabytes free, but the phone stubbornly reports that it cannot install an application of a couple of tens of megabytes in size. This is because the section for third party programs already filled to the end.

In such cases, there is nothing left but to try to clear the system memory in the hope that you will be able to free up these megabytes.

You can see the amount of free system memory in the settings, in the “Memory” section. The first scale shows exactly this value. In addition, it is worth considering that the system requires leaving a certain amount free - from 50 to 600 megabytes, depending on the Android device model and OS version.

Cleaning system memory without superuser rights

If you have not opened root access on your smartphone, then your ability to clean up the system partition will be seriously limited. On the other hand, the warranty on the device will remain intact. Is it worth it? It's up to you to decide.

If you want to clear system memory, do the following:

Go to "Settings".
Go to the "Applications" section.
Next, go to the “Third Party” tab.
Click the Menu button (three vertical dots in the upper right corner of the screen).
Select sort by size.

.png" alt="List of Android phone applications" width="300" height="169" srcset="" data-srcset="http://androidkak.ru/wp-content/uploads/2015/09/spisok-prilozheniy..png 300w" sizes="(max-width: 300px) 100vw, 300px"> !} After a couple of seconds, you will see a list of the largest applications on your device. If there is something among them that you do not use, then click on it and select “Delete”. If the button is not available, it means that the application is a system application and cannot be erased without superuser rights.

Then select “Uninstall updates”, this way you will free up at least some space. It is also advisable to disable the program by clicking on the corresponding button. But this must be done carefully and only with applications like Facebook that are not part of the system.

The above method does not take into account the fact that Android calculates the size of the application on the entire internal memory. If it takes up 1.2 GB per internal map memory and only 40 MB on the system partition, it will still be shown with a size of 1.2 GB.

If you have already carried out such optimization and there is still little space, you have little choice: get superuser rights or try to transfer applications to a memory card. The latter will only work if your system is version 4.0.4 or lower, so the chance is slim. But if you really are a user of a device that is at least three years old, then next to the “Delete” button you will have a “Move to SD card/USB drive” button. Click on it, and part of the data of this application will leave the system partition and will be transferred to the memory card, freeing up space.

Some Android programs are used only by some third-party applications, so they can be erased even without superuser rights. For example, deleting " Google Services Play" allows you to free up to 150 MB in the system partition, in return closing the possibility of direct synchronization between devices. If you don't use programs like Pushbullet or MightyText, you can safely delete this. And if some program suddenly needs something, it will offer to download it again. The second candidate for deletion is Google search, but along with its 40-60 MB you will lose Google Now and the “Ok, Google!” command.

Cleaning system memory with superuser rights

And although we will further discuss unstable solutions a la Xposed App2SD, which, for example, allow you to replace the application section with a memory card, root users still have more options.

Removing pre-installed programs

If your Android already had installed third party applications(Facebook, VKontakte, Odnoklassniki, MTS Assistant), then most likely you will not be able to delete them without superuser rights. This is quite a shame, because they often have significant sizes of 40-160 MB.

The solution is the Titanium Backup program, which allows you not only to make a complete backup of all your applications with their settings, but also to clean the closed system partition from such garbage. To do this, simply select the desired application on the second tab of the program and click “Delete”.

Mounting an SD card as internal memory

As mentioned above, 1.5 GB of a game does not always go completely to the system partition. But for those who have internal memory of a couple of gigabytes, this does not make it any easier.

Jpg" alt="Folder Mount program" width="150" height="119"> !} The solution is the FolderMount program, which allows you to transfer cache files (that’s what these one and a half gigabytes are called) to a memory card, leaving a shortcut in their place. In this case, the system will still consider that the files are in the old location, which leads to funny oddities in the “Memory” settings section: for example, you can see that you have 8.2 GB of 3.6 GB occupied, while another 0.98 of these 3.6 are completely free.

If FolderMount cannot create a folder on the SD card, do it yourself by any file manager and indicate in the program. You can also immediately copy the files of the transferred program there, deleting them later from the internal memory - it’s more reliable. And if you see a message that mounting is impossible, turn on “Autostart” or “Mount at startup” in the settings and restart your smartphone.

Other partition extension methods

Data-lazy-type="image" data-src="http://androidkak.ru/wp-content/uploads/2015/09/App2SD.png" alt="App2SD App Manager Save Space" width="100" height="100" srcset="" data-srcset="http://androidkak.ru/wp-content/uploads/2015/09/App2SD..png 150w" sizes="(max-width: 100px) 100vw, 100px"> !} There are other ways to transfer data from the system partition to a card or internal memory. However, most of them are extremely dangerous in the hands inexperienced users, is only suitable for a specific model/make or requires a high level of technical skill.

Most users of mobile devices working with operating system Android may encounter problems that are associated with memory overflow. There is no universal solution to get out of this situation. But it is better to listen to some recommendations.

The article is devoted to the question of how to free up the memory of an Android mobile device. First you need to familiarize yourself with its types. This will allow us to deal with the problem on a global scale. It is worth noting the following types of RAM:

RAM, RandomAccessMemory or RAM;
ROM, ReadOnlyMemory or ROM;
internal drive Interal Storage;
microSD/microSDHC or ExternalStorage.

RAM, RandomAccessMemory or RAM

This RAM serves for recording by the operating system and software all necessary data. Thanks to this, applications launch and function without failures. It is worth noting that when you turn off or reboot the device, it is cleared in a fairly short time; the RAM needs constant power. As you know, the larger the volume of RAM, RandomAccessMemory or RAM, the more applications are launched simultaneously on a mobile device. In addition, by its size you can determine what capacity of resources can be launched on your device without problems.

If the RAM is full, an error occurs when starting a new application. The user will receive a notification that there is not enough space to play. Thanks to the rapid development of technology, today there are versions of Android 2.2 and higher. In such devices, the operating system independently determines what exactly needs to be removed, as well as which applications need to be closed to free up space.

Currently, most flagship devices are equipped with memory with a capacity of 1 Gigabyte, and even 2 Gigabyte. That is why the problem with its overflow occurs less and less often. As for inexpensive phones, tablets and smartphones, they have a capacity of 512–768 MB. In this case, the issue of freeing up RAM is still relevant.

ROM, ReadOnlyMemory or ROM

RAM is used exclusively for reading. It stores data that was recorded at the manufacturer's factory. They cannot be changed. The only option is to flash the device or reinstall the operating system. ROM consists of several sections that are designed to perform various internal functions.

Interval Storage

It is an internal storage device. It stores all the information that is entered by the owner of the device. The internal drive is analogous to the hard drive used in a computer. When recording all kinds of applications and data, the free space of RAM decreases. To free it up, it is enough to get rid of excess material that is not used. The remaining capacity for data recording can be seen in the device settings. Therefore, often freeing up RAM space is directly related to cleaning the internal storage.

microSD/microSDHC or ExternalStorage memory card

It is a removable memory. Its volumes depend on the card used. True, it is worth considering the presence of the necessary spot in the device, as well as whether it is supported by the device. MicroSD/microSDHC or ExternalStorage can be compared to an external hard drive that is used by a computer. Phone settings will provide all the necessary information about the volume free space. On such a card it is convenient to store multimedia materials, which include music, images, and videos. Android versions 2.2 and higher allow you to transfer all data to the card. As a result, space on the internal storage is freed up. When removing a card, it is advisable to first unmount it.

Freeing up internal memory on Android smartphones

Most users tend to install more different applications on their own device and modify programs. As a result, the gadget will definitely notify him that the system is full. To clean it, you need to download an additional utility or use the settings of your mobile device.

Thus, the user will definitely know that the memory on his device is full. When downloading the next application, the system will display a corresponding message on the screen. To be able to save the material, you can delete unnecessary objects. This will free up space for the required application. As a rule, large volumes are occupied by various updates coming to GooglePlay. A certain number of programs can be moved to the card when using Link2SD.

InternalStorage can be accessed if you have Root rights. This also promotes effective cleansing. You also need to get rid of temporary files with the .rm extension. They are saved in the datalocalmp folder and tend to constantly accumulate and clog the system.

Selection of events

All of the above steps involve temporarily clearing the gadget’s memory. Is there a thorough method to free up the internal storage on your phone? During the installation of programs on a tablet or smartphone running the Android operating system, a file with the extension .dex is created in the datadalvik-cache directory.

Sometimes it happens that some system applications do not have them. At first glance, it is a rather strange phenomenon when a program exists, but does not take up space at all. However, this is quite understandable. The fact is that at the same time as these files, the device’s memory contains files with the same name, but with the extension .odex. You can save them, but then you don’t need to leave the .dex files. Recommended download additional application. An example of this is LuckyPatcher.

After this, you should start performing certain actions that will help you find the answer to the question of how to unload internal memory on Android versions 2.3.6 and higher:

1. First, you should check how much space the application takes up. To do this, use the “Properties” menu.
2. LuckyPatcher starts, after which the required application is selected from the list.
3. You need to click on its icon and hold it down, pausing. As a result, a context menu will pop up on the screen.
4. You must select the first two items. The program will automatically create the necessary odex files.
5. Dex is removed from the datadalvik-cache folder.

After completing all these steps, the application will work perfectly and not create problems, occupying 0 MB. In the same way, you can free up memory for other system applications.

To clear memory from user applications, you need to use a slightly different method. You need to select an application and go to its folder on the memory card. As a result, you can see the free space. For example, there is 1.56 MB of unallocated space, but the dex file covers 1.68 MB. Thus, you can transfer the required application to the system directory. Then the steps described above are performed.

You can also simply select another application and leave this one alone. When an object is moved to user memory and an odex file is created, and then the dex file is deleted, the device performs well. It will cope perfectly with the assigned tasks, open required applications and use them without failure. If you transfer the object to a flash drive, the odex file is deleted, and the program itself stops working. As a result, you will need to install it again or completely clear dalvik-cache.

It is worth taking into account that not every utility can work without dex files. This is typical for games or applications with a dex of up to 1.5 Megabytes. This method is relevant exclusively for those applications whose dex files weigh less than the available memory space. Thus, the steps to answer the question of how to free up internal memory on an Android device are not difficult; they are easy to complete.

Daily in search engines There are only growing queries about what RAM is on a smartphone, how it can be changed, measured, and increased.

How to increase RAM on your phone is the most popular request, of course. But the fact is that over time, your smartphone begins to work slower and become glitchy, and it’s all about that same RAM.

In general, RAM is a special type of memory that is present on a modern phone. And in order to answer the questions, you will have to explain what types of memory there are, and how they differ from each other.

1. What kind of memory is there on the phone?

Modern phones include three types of memory:
1. RAM, aka random access memory, in English RAM. This type of memory stores information about those processes on the device that are currently running. It is very energy-dependent and processes only the information that is working right now. If the phone loses “power” and turns off, then the RAM data disappears.
2. ROM, ROM– a read-only storage device, or non-volatile memory, which is used specifically for storing data on the phone. This memory is not deleted and does not require a power source. This memory stores information about the processes that have ever been running on the phone. To simplify, such memory can also be called a cache, because it stores all the required files for applications and their operation. They will not be deleted until the user wants it.
3. Internal storage or Internal memory. This is the type of memory that stores all user data: photos, music, videos. It can also be expanded via microSD cards.

Apparently, only the number of simultaneous applications running depends on the RAM. It turns out that the more RAM, the more processes the smartphone can perform.

RAM constantly changes information, while information in ROM does not change.

About internal memory - its changes directly depend on the smartphone user. The internal memory is used for movies, music and other files.

RAM can only be changed by the system. But the ROM can be changed by the user if he has Root rights, that is, administrator rights.

To obtain such rights, you will need to do some additional steps to “hack” the phone.

2. How to find out the amount of memory on your device

The answer to this question will be provided gradually. To view the amount of RAM on your smartphone, you need to do the following:
- For Android devices - download CPU-Z tester, or Antutu Benchmark to check RAM.

- For iOS devices - download Antutu Benchmark, or another well-known tester.
- For Windows Phone devices - go to your phone settings and view the data in the “Advanced” item.

On the OS, like BlackBerry, where there is no option to download the tester, you just need to go to the official website of the manufacturer and view the characteristics of your phone.

In order to find out how much time the ROM is currently in use, you need to do the following:
- For Android– download task manager, like Clean Master and see the amount of memory used.

- For iOS– task manager, “System from the inside”;
- Symbian– task manager “Acces APPS” or others.
You should also look for task managers on other platforms.
As far as I know, there is only one such manager specifically for Windows Phone, and this is “Device Diagnostics HUB”.

As for the total amount of shared memory, you can view it through Antutu.

3. How to free up RAM

This is very easy to do, you just need to disable those applications that take up “RAM”.

Of course, you won’t be able to disable everything, because many are needed for the system to function. But you can disable unnecessary ones using the application “ Advanced Task Manager"- the application is available on both iOS, Android and Windows Phone.

The application is able to “kill” processes and free up RAM. At first, the program will show running processes and the amount of memory they occupy. To close any of them, place the stick and click on " Boost».

The same process can be performed standard means OS, but not all.

For example, Android has its own “ application manager”, but it is limited and does not provide information on how much a particular application is using.
Depending on running applications, it can be deleted, stopped or turned off. All these options will free up memory from this application.

To view the Application Manager, go to " Settings", after " Applications", and then select one of the applications and there you will see the buttons that were discussed.

4. How to increase RAM on your phone

It's very simple - remove all unused programs. Of course, there are no software methods for increasing RAM, and it is impossible to increase its volume. This volume can only be released.

Especially for cleaning RAM, there are “cleaner” applications that remove “cache”, temporary files, ad junk and other files. This garbage significantly slows down the system. The downloaded application will automatically analyze the phone system and delete unnecessary files with the user's consent.

- Cleaners for Android: Power Clean; Avira Android Optimizer; CCleaner.
- Cleaners for iOS: Clean Doctor; PhoneClean; PhoneExpander.
- Cleaners for Windows Phone: Storage Cleaner; RAM Master Pro; RAM Optimizer by Kovlag.
- There is only one cleaner on Symbian: Mobile Cleaner.

How to clear phone memory on Android? - This is a question that interests many smartphone users. Insufficient memory is one of the most common problems, as it can appear even on smartphones with large amounts of storage. Typically, a problem is indicated by the system message “Memory Full”. In this case, the device may indeed not have free space, and sometimes there is enough of it. This problem leads to a ban on downloading, updating, creating photos and videos. The phone turns into a device of little use, devoid of most functions.

The way out of the situation is to free up space or change settings. We will show you 5 effective ways to eliminate the lack of free space on your smartphone.

Cleaning your phone from unnecessary files

If your Android phone's memory is full, the first thing we recommend is deleting apps, downloads, and system junk. The largest amount of space on a smartphone is occupied by the download folder and installed applications. Effective way free up enough memory - remove everything unnecessary.

Analyze all applications on the smartphone's desktop. Most likely you will be able to find several unnecessary or few useful applications, which have not been used for a long time. It is better to delete them in order to free up memory;

Another common reason why your phone's memory is full is because it stores a lot of videos and photos. We can filter out bad photos and useless videos. This may already solve the problem. If all the media data is needed or deleting it did not help free up enough memory, all that remains is to transfer the . We recommend moving the data to a flash drive or transferring it to a computer;
Clear downloaded files from messengers. They download sent photos to your phone by default. Because of this, various postcards, congratulations, photos of strangers, etc. accumulate in the smartphone storage. The easiest way to clear this partition is to use your computer. Through Explorer we can open the folder of the same name from the messenger and remove its contents;
Check the folder where the browser downloads all files. A lot of data accumulates here; cleaning it will help free up a lot of space.

These are the most effective ways to free up space on your phone, but they don’t work for everyone. Is the low memory problem still there? – Read on.

Removing information from the .thumbnails folder on Android

Probably few people know, but when viewing the gallery Android system creates sketches - these are small snapshots of pictures. Their main task is to increase the speed of the next file download. It's easy to guess that these sketches take up space and have minimal practical use.

We connect the smartphone to the PC and enable the “File Transfer” mode.
Open the “DCIM” section in the phone section.
Go to the “.thumbnails” directory.
Press the combination Ctrl + A and delete all content.

Over time in this section 1-2 GB of data accumulates. Only removing them will help the phone, perhaps it will even stop slowing down.

Important! We recommend performing this action at regular intervals. Depending on the activity of smartphone use, this is 1-3 weeks. If we forget to clean up, the same number of files will accumulate in the partition again.

Clearing cache

Another way to painlessly free up space on your phone is to delete the cache. Cache is temporary files designed to speed up data processing. Actively used data is placed here. Instead of re-processing the data when the application loads, it is simply taken from the cache.

As in the previous case, in small quantities the cache is useful, but in large quantities it can slow down the smartphone. This procedure is ready to give from 500 MB to 2-4 GB of free space and even more.

How to clear your phone storage by deleting the cache:

Open the Settings application.
We look for the “System and Device” section and click on the “Storage” item.

After calculating the data occupied by the cache, click on the “Cache data” item.

In the “Clear cache” window, select “Ok”.

By the way, due to an incorrectly formed cache, there is a situation when the phone’s memory is full, although there is nothing there. Usually a utility for accessing the official store Google Play reports that memory is busy. This notification appears when you try to install any application.

How to clear Google Play cache:

In the “Settings” menu, look for the “Applications” section.
Select "All applications".
Find the line “Google Play Store" and click on it.

Click on the “Clear” button at the bottom and select “Clear cache”.

Healthy! Often, special applications are used to delete the cache; they do not require root access and do everything in a couple of clicks. For this we can use CCleaner or Clean Master.

Changing settings on an Android smartphone

Now let's learn about a method that is ready to give more free memory than any other method. This is a radical way to free up memory on your phone, the essence of which is to reset the settings to the factory state. The local storage will be formatted. The end result is a completely clean smartphone.

Go to the “Settings” menu and find the “System and device” item.
Open “Advanced settings” and at the end of the page click on “Backup and reset”.

At the bottom of the list, select “Reset settings”.

Click on “All files on the phone” and confirm the action.

We left one more for last good way, which requires a small cash investment.

Replacing the memory card

We can simply purchase a larger microSD card. Modern smartphones usually support 128 GB drives. With such a storage volume, there should be no shortage of space.

Important! Many smartphones have a combined slot. This means that we can install either a 2nd SIM or microSD card in the second slot. You'll have to set your priorities correctly.

Brief summary: Insufficient memory can be easily eliminated by deleting temporary and useless files. If you want to save all the data, you can simply install a more capacious flash drive. If a lot of the data on your phone is out of date, it makes sense to transfer everything you need to your computer and format your smartphone. A factory reset frees up the most space.
