The memory full problem, which can be identified by the message issued by the Android operating system “Memory Full,” is quite common. Moreover, there are no universal solutions for it, but there are many tips. In this material we will try to systematize all, or at least most, of the available information on this issue.
RAM, Random Access Memory or RAM - random access memory or random access memory. Software (including the operating system and installed applications) writes the data they need during operation into this memory and can quickly read it. RAM requires constant power - when you turn off or restart the device, it is completely cleared. The more RAM, the correspondingly more different processes and services can be launched simultaneously. The “Phone memory is full” error may occur if the entire amount of RAM is completely exhausted, and there is not enough free space for the application being launched.
ROM, Read Only Memory or ROM - read-only memory. The information stored in it cannot be changed and is recorded when the phone is manufactured, or when the operating system is reinstalled - that is, during the flashing process. ROM is often divided into several sections to perform internal functions.
Interal Storage (Interal Phone Storage) – internal storage of a smartphone (or other device). This memory section is designed to store user data, installed applications, and so on. This is something like an analogue of a hard drive in a personal computer. Naturally, in the process of writing data to the internal memory of an Android device, the free space here becomes less. The total storage capacity and the amount of free space can be viewed in the device settings.
External Storage – or, essentially, a microSD/microSDHC memory card. The user can expand this type of memory at will, if, of course, the device supports memory cards and there is a corresponding slot for this. It is something like an external hard drive for a personal computer. The total and occupied volumes of this type of memory, as well as the free space on the card, can be checked in the settings of the Android gadget. You can store multimedia data such as music, movies, pictures on a memory card. Starting with Android 2.2, it became possible to transfer installed applications to a memory card if the application itself supports it, thus saving space on the internal storage. Before replacing a memory card, it is strongly recommended that you first unmount it rather than simply removing it from the device.
Usually, after some time of relatively “quiet” use of a device on Android, users begin a period when they want to modify this very device in every possible way programmatically. The endless installation of applications, scripts, and so on begins. And sooner or later the message “Phone memory is full” appears, especially if the model is not one of the “top” ones, and there is not that much memory. It is logical to assume that the problem is in RAM - yes, this is partly true. But cleaning it up is much easier; this can be done both through the settings and using various downloadable utilities. So, a message about a lack of memory in the device appears when the internal storage is full. Of course, you can constantly clean this very drive, remove unnecessary applications, and so on, but over time it will be seen that the notorious “Phone memory is full” will appear more and more often. What is this connected with?
On Samsung devices, press and hold the Home button for about a second, then go to the memory icon.
The data here is displayed in the format "Occupied/Total", so you will need to remember a little arithmetic lessons.
Everything is simpler here: Settings > Options > Memory . And you don’t need to count anything.
For a quick, although not very long-term, solution to the situation, clearing temporary files will help. They have the extension .rm and are stored in the folder datalocal mp. You can delete temporary files with Root access, for example, using Root Explorer.
Also, in the above folder data you can find many files that have the extension .log and contain “error” in the name - these are log files of errors from various applications that take up quite a lot of space. We delete them and forget about “Phone memory is full” for a while.
Now let's look at a more thorough method of cleaning space on the internal drive. Each program on a smartphone or tablet, or any other Android device, when installed, creates a file with the extension .dex in the directory datadalvik-cache. But sometimes, on some system applications these files are missing, and the following picture is visible:
It's really strange that the program takes up 0 bytes. As it turns out, the reason lies in the fact that along with these files, the firmware contains files of the same name, but with the .odex extension. These files can be created, and then there is no need to leave the .dex files. For example, LuckyPatcher can “oddex” applications. So, first, look in the application properties to see how much space it takes up:
In this case it is 1.68 MB, so the corresponding .dex file is in datadalvik-cache takes up the same amount of space, and the created .odex file will weigh the same. We launch the mentioned LuckyPatcher, select the desired application in the list, press on it (not just “tap” once, but press and hold), we see the context menu:
We select the first or second item, and it does not matter that the application may not need to remove license verification or remove advertising at all. After this, the program will create the .odex files we need. You can now remove .dex files from datadalvik-cache. And now we see that the application already takes 0 bytes, but it works fine. This method is suitable for system applications.
For custom applications, everything is a little different. We select the application we need and go to its folder on the memory card, look at the free memory of this application. In this example, 1.56 MB is reserved for the program folder, while the .dex file occupies 1.68 MB.
There are several ways to solve this problem: either move the selected application to the system directory and carry out the manipulations described above, or forget about this idea specifically with this application and take on some other program. By the way, if you move the application to user memory and then create .odex, you can delete .dex, and the program will work normally. But when you move it to a flash drive, the .odex file will be deleted and the application will refuse to work. In this case, there are only two options left: reinstall the program again or do a complete clear of dalvik-cache. So not every application can work without .dex - the method will only work with applications that have more free memory than .dex.
You can solve the problem radically by using Hard reset - a hard reboot of the communicator. This is a good step, returning the device to its original factory settings. The speed of operation increases, the smartphone instantly responds to all input and literally begins to “fly”. But, on the other hand, such an action can cause inconvenience for the user, because this is the deletion of data, files, applications that he will be forced to install again.
To get rid of unused apps, go to Settings > Options > Application Manager.
Once in the “Downloaded” tab, call up the menu and sort the files by size. Next, select the applications you abandoned and click “Delete”.
You can only remove updates from applications that you installed yourself - a similar trick won’t work with built-in ones.
Select the application, click on “Uninstall updates”, and then click on “Disable”.
If you have root, then you can even get rid of system software. But be careful - one awkward move and your smartphone will fall asleep.
To clear the application cache, go to: Settings > Options > Memory.
Wait a few seconds until the amount of occupied space is determined, then select “Cached Data” and tap “OK”.
I can’t say that this method is super-effective, given that some utilities themselves take up a lot of space and even display advertising. Therefore, if you decide to resort to it, then choose the proven CCleaner.
After the utility has done its job, you can safely delete it - until the next need.
“Phone memory is full” is certainly one of the most unpleasant and annoying messages for Android device owners. We hope that thanks to our advice, she will not bother you for a long time.
Problems related to smartphone performance are very relevant these days, and any owner of a modern device would not want to face them. But, unfortunately, even any top-end flagship will start to fail after months of use. We want to make you happy, because this problem has a solution. This article will help you get rid of lags on your phone.

Have your eye on a brand new smartphone, but want to sell your old one before buying? Have you given your phone a proper presentation, but can’t return it to its former functionality? You need to prepare your phone for sale. How to clean your phone completely?
All current mobile devices running the Android operating system are tied to an individual postal address. Therefore, when selling, the presence of viruses, or simply cleaning, you need to quickly clean the phone “to zero.” This goal can be achieved in several ways:
How to completely erase a Samsung phone to factory settings? The method is very simple, so we recommend it first:
After the phone restarts, you will see pure Android.
Important! It is necessary to fully charge your smartphone before this procedure.
Turn off your phone. Now you need a combination of control keys. There are several most common variations:
Important! The combination should bring up the Recovery menu, controlled by the volume keys, and selected by the power button.
You need to find the factory reset item and select it. We agree with the choice and wait for the smartphone cleaning procedure to start.
There is an opinion that standard device cleaning tools are not as effective as data removal tools offered by different companies. How to completely clean your phone in other ways?
Important! All instructions given above are relevant for new versions of Android and may differ slightly on different devices.
If you need a “clean” phone for sale, then in order to speed up the performance of the device, you don’t always need to tear everything down. There are many programs that can keep your system clean.
You can get rid of lags and freezes. What is needed for this? Most often, it is enough to install special applications that will help clean and speed up the system.
There is a list of tips that will help you get rid of the “brakes”:
You won’t have to set up your phone as often as you will have to get rid of junk on it. Cache from surfing the Internet, the consequences of background running of applications - these are only a small part of the sources of so-called “pollution”. Let's try to analyze the cleaning process in more detail using the example of using the Clean Master program.
Clean Master is a very convenient, intuitive and functional application for cleaning the internal memory of your phone, which can also speed up and optimize the operation of Android devices. In order to carry out the procedure, you need to launch the application itself, select “Trash” and “Clean”.
Important! The app will prompt you to do an advanced cleanup and notify you that this partition may contain important data. Be careful!

This article should help you clean your Android device of unnecessary information and erase files you no longer need. We hope that now you can easily solve the problem of Samsung phone freezing or give it a factory “state” with characteristic performance. If this article did not help solve your problem and correct the operation of the device, we recommend that you contact your nearest service center or consult a qualified specialist.
Active users of Android mobile devices often encounter a situation where a fast and responsive device begins to “slow down” - installed applications take a long time to open, pages load slowly in the browser, the gallery “freezes” before opening, etc. This may be caused by accumulated “garbage”, which interferes with the operation of programs.
We will look at how to solve the problem of clearing memory using the example of Samsung mobile devices.
Let's first prepare the phone for work.
As a result of the procedure, all data will be deleted from the phone, therefore, before proceeding with the corresponding manipulations, you need to make backup copies of all important information for you - contacts, photographs, programs, etc.
Check the condition of the battery, if necessary, charge to maximum values.
Now turn off your gadget completely.
With the device turned off, you need to simultaneously hold down three buttons - the volume up key (up), the device power button and the physical button (home) located below the display, as shown below in the still frame:
The phone will start to boot, but in reset mode:
In the menu that opens, use the volume rocker to select “ wipe data/factory reset»:
By pressing the power button, we confirm the action, after which a submenu will open, in which (also using the volume up or down key) select the line “ Yes — delete all user data", press the power button, which in this case activates the reset process.
Now, when the menu appears, select the line “ Reboot system now"(don't forget to confirm the action with the power button):
After the manipulations have been performed, absolutely all information will be deleted from the smartphone (tablet), and along with it what is called “system garbage”, the device will return to the “as from a store” state, will automatically reboot, and we will only have to return the saved data.
This option does not exist on all Samsung devices. You can find out by performing all the necessary actions for which “superuser” (ROOT) rights are not needed. So what we need to do:
On your smartphone, enter the engineering menu code in the dialing line *#9900# and press the call button:
In the window that opens, select the item “ Delete dumpstate/logcat»:
If this item does not appear, then due to the lack of a function in your device, you will have to use another method.
A fairly simple way to clear memory is to use the built-in task manager. What actions should we take:
Press the physical Home button located in the center at the bottom of the device and hold it for a couple of seconds to open the task manager. Then, click on the virtual button in the lower right corner to close all applications, after that, click on the button in the lower left corner, which activates the deep cleaning process:
In the window that opens, a system message will appear indicating what will be deleted as a result of the procedure. All you have to do is click on the “Clear memory” button:
In order to apply this method, we will need (or another file manager) and . Since in this case we will be working with system files, it’s worth immediately recalling that rash actions can lead to dire consequences when your phone can be used for other purposes than its intended purpose, but, for example, as a cool stand for a cup of coffee, or something else. , what your imagination can tell you.

The article shows in detail how to free up phone memory. Cleaning methods are described for beginners, advanced and experienced Android users. General recommendations are given for expanding disk space and maintaining storage in optimal condition.
The following methods of clearing memory are distinguished:
Each method is focused on the knowledge and capabilities of users. Therefore, the available methods in our article are arranged in increasing complexity. Let's start with the simplest...
In Android, a general basic analysis of the occupied internal memory space is available. Detailed analysis is offered only by third-party applications, for example, . But a basic analysis is enough to find out what memory is being used for.
In Android version 5.0, a graph appeared with the calculation of cache - temporary data. Such files appear while using applications. The more frequently and more actively programs are used, the more cache accumulates. For some users, the volume of temporary files is 500 – 2500 MB.
To clear the cache, do the following:
Third-party apps offer in-depth analysis and advanced memory cleaning. For example, the application can clear the cache, as in the previous method. And also delete applications and look for duplicate files. The program offers manual and automatic cleaning methods. This allows you to mark and delete more “unnecessary” files at once.
Some similar programs analyze application usage time. Unused or rarely used applications are suggested to be deleted.
If available, system applications can be deleted or frozen. Also move it to a memory card, which is important for large games.
Such applications work on the same principle.:
Cleaning phone memory using SD Main app
Manual cleaning is the best and safest way to remove unnecessary files. The procedure is long and monotonous, since it is necessary to check the attachments of each folder separately. Skills in working with the Android file system are important, as is an understanding of what a particular file is responsible for. In this case, the likelihood of accidentally deleting important information is noticeably lower compared to automatic cleaning.
For manual cleaning you will need one, preferably with the “occupied space analyzer” function. The same one will do. Large selection of file managers, see our applications.
Algorithm of actions:
The last, radical way to clean Android. Resetting will delete all data on the internal drive, including most viruses. It will also return applications and system settings to their original state. After complete cleaning, it is enough to reconfigure the system. In addition, changes made using root rights will return to their original state. , read in a separate article.
Resetting your phone
Internal memory is used by default for most tasks. Here is an incomplete list of such tasks.
Modern mobile devices are equipped with an impressive amount of internal memory, which can reach 64 GB or more. This space is sufficient for most users to perform everyday tasks. However, if your gadget does not boast a capacitive drive, sooner or later you will face a lack of free space on your device. In this case, it will not be superfluous to know how to clean your Android phone of unnecessary files and applications.
Starting with Android 4.4, the developers of this OS have removed the ability to install applications on an external memory card. Thanks to this, many owners of mobile devices began to experience a shortage of free space and look for different ways to free it up.
There are several ways to clean Android from unnecessary files and programs:
The most accessible and easy-to-use method of getting rid of unnecessary data is manual cleaning of Android. It consists of searching internal and external storage for files and programs that you do not use, and then erasing them.
The most convenient way to clean your phone of unnecessary files is through the explorer installed on your smartphone. This could be File Manager, ES Explorer, Total Commander or any other software with similar functionality. The procedure will be as follows:
If ES Explorer is used as a cleaner, then in this case unnecessary files manually deleted will not disappear without a trace, but will be transferred to a backup area called the Recycle Bin. To completely erase them, you need to clean it too.
If, after cleaning the gadget from rarely used files, little free space has increased on the drive, you can additionally get rid of unnecessary software:
This cleaning method is only suitable for third-party applications. There is no virtual Delete key in the properties of the preinstalled (built into the system) software. Before uninstalling such programs, you will need to unlock root access on your device.
When considering how to clean Android of junk, it should be noted that one of the places with a large volume of unnecessary files is the Download folder. Therefore, it is recommended to visit it first.
Another place where garbage likes to accumulate is cache. It stores temporary files, as well as “snapshots” of previously deleted applications. One of the most effective cache clearing utilities is SD Maid. It works like this:
Deeper cache clearing can be done via . To do this, you need to enter Recovery mode by turning off the phone and holding down a certain combination of mechanical keys, and select the wipe cache partition tool. After rebooting the phone, the cache will be completely clear. 
If the memory of your device contains only the necessary information, that is, you cannot delete anything from it, you can free up free space by transferring the installed software to an external card. Modern smartphones and tablets do not have this feature. However, this shortcoming can be corrected.
