Freeing up the built-in memory on Android. The best apps for cleaning garbage on Android Internal memory disappeared on Android what to do

Android users are often faced with the fact that some time after the start of use, the "system" memory disappears somewhere. This also applies to users of budget versions of smartphones and mid-range ones; rarely only concerns flagship users, although it shouldn't hurt them to read this note. Moreover, the majority of budget devices are still on hand.

When you buy an android smartphone for the first time, it is not clear whether the memory specified in the specification will be enough for real tasks. My first android smartphone was Samsung Galaxy Gio GT-S5660, with 178 megabytes of "internal memory". Thoughts when buying: “So, the basic applications are already installed. I also buy a memory card for multimedia, files and other progs. And those that will not be able to establish themselves on the map - for them, and 178 meters with the head. "
And after a while, understanding and disappointment comes. But let's talk about everything in order. Let's try to understand the basic concepts in file system and how to “cure” the problem at a minimal level. I am oversimplifying the material so do not look for "inaccuracies" from the point of view of Computer Science.

The android operating system is based on Linux. If we look at it from the root, we will see approximately the following picture:

Approximately the same as in any Linux. I will not describe all the folders - if you need it, read the relevant literature. Now we are interested in “built-in memory” and “system memory”. Where is it and what?

The android operating system itself is installed in system memory... These are all the files and folders you see in the screenshot, except for a couple. Manufacturers do not write about this memory anywhere and never (in any case, I have not seen it, if you have seen it, show it). You will not see “XXX MB System Memory” in any press release or specification. Everyone is here system files that are of little interest regular user... Using special utilities, you can still see it. In the Galaxy Gio, the system memory is 206 megabytes, but we are in this case interested in one folder / system / app.

This folder contains all the “pre-installed” applications. Here are also those programs without which a smartphone cannot function normally, for example, a “dialer”, all sorts of “synchronizers” and those that were installed by the vendor (phone manufacturer) by default: Youtube, some office or “operator's” software.

But where do we have that “built-in memory” or “user memory” ?. Speaking simple language, it is in the directory / data... It would be more correct to say: “a section of the internal non-volatile memory available to the user is mounted in the file system as a directory / data“, But I'll keep it simple.
What's in this directory? The novice user thinks he has been given all the space of the built-in memory (in my case 178 MB) at full disposal.

No matter how it is! After the first start, this directory is filled with directories with files. Again, I will not dwell on all the directories, but will only talk about the main “eaters” of the place.
The first directory is dalvik-cache... The android part is Dalvik Virtual Machine- Google's own implementation of virtual java-machine in which all applications are launched. Dalvik cache is an intermediate buffer with fast access. Simply put, android puts precompiled program code here in order to speed up their launch. Moreover, it does not depend on the type of program: at least system, at least in user memory, at least on a memory card; dalvik-cache in one place - in / data... For example, on Galaxy Gio, this folder after the first start takes about 100-110 megabytes. Well, 178 megabytes of memory for the user unexpectedly turns into 60-70. Sadness-sadness. You can't do without this cache. There are a number of instructions on the net that allow you to transfer it to external card memory. Of course, this affects the performance a little, and there are glitches. I will not describe this technique. (If you have your own description of this method, knock - we will exchange links)

We look further. Folder / data / app... All user programs that cannot be transferred to a memory card for some reason are installed in it. There are usually two reasons. The first is a widget: such programs cannot be transferred to the map due to OS limitations. Second, the developer did not think about users of budget smartphones.

Now for the biggest surprise, which is why I started writing this post. When a system program such as Youtube is updated, its apk also fits in / data / app... And we get the following: in / system / app lies, not going anywhere, old version programs, and in / data / app- new. Of course, “parts” of the program are also in dalvik-cache, and in other caches and places, but this is as usual, but we do not need such a “doubling” at all. It turns out that even if you did not install any programs yourself, after a while the user's memory (/ data / app) will be spent on updating the system programs (of course, if you update). Android will not move this apk itself to / system / app never.

What to do?
First, you need to get, otherwise the system won't let you write anything to / system / app.
How to get the root for your specific device I suggest you search the Internet yourself or browse this topic on w3bsit3-dns.com.

Root-rights are not scary. Often, users of competing systems present this as some kind of terrible villainy that allows you to do no one knows what. For example, "pirate" - like with JailBreak on iOS. For "piracy" on android, all this is not necessary :) A smartphone with enabled root-rights only allows some programs, the list of which is controlled, to always or temporarily obtain the right to write to system directories. And that's all. How sudo on the linux or in Run as administrator" on the windows... Fearfully? No. Now, on some firmwares, the root is turned on simply by a switch in the settings.

The second point we need is the SystemCleanup program

Donat program. That is, at each launch, she asks to buy for about $ 3 Inteks Donation Key, which is suitable for several programs of the author, but this does not take away the functionality. In general, the program allows you to do a lot of things: “code” applications (maybe I'll talk about this later) on the device itself, clear the cache, delete system applications, do backups and much more.
Consider only restoration of universal justice transferring the updated system programs to their place.

Run the program and switch to the tab Apps.

Here we see a list installed applications with additional information. We are looking for programs under which it is written in red system + data... These are our "penalties". Clicking on a line will show additional information about the place occupied by this application in different “memory locations”. We make a long tap and choose “ Update system app”(The screenshot is old, now the inscription is like this) and agree with the action in the additional dialog box. Usually, after all the movements, a reboot of the device is required, which the program will offer to do.

In such a simple way, you can free up several tens of megabytes of valuable user memory occupied by clones.

In general, I repeat, the program can do quite a lot of useful things. For example, you can uninstall pre-installed system apps that you don't need. Moreover, under most applications there is a hint: is it safe to delete it. You can transfer the application from the main memory to the card with full functionality (only if it is not a widget). And you can make some applications "system". For example, you freed up several megabytes in system memory occupied by unnecessary operator software, and at the same time installed a third-party “dialer”. It is not advisable to transfer it to a memory card because of its speed or fault tolerance, and it takes up space in the “built-in memory”. Long tap and choose Move app to / system / app and your program has moved to the folder / system / app, that is, it has become systemic (from the point of view of an android).

That's all for today. Once again: the program has many useful functions, learn them yourself, or maybe I will describe it someday. There is more radical methods of "expanding" user memory related to remounting the dalwick cache or folders in general / data to a memory card, but they are associated with certain risks and other inconveniences.

If the phone memory is full, then you need to free up space. Removing cached data filling spaces will help keep your Android running smoothly. You can clean Android from garbage manually or using special cleaning applications.

Manual cleaning

If the phone has not been cleaned for a long time, then the user faces a number of tasks:

1. How to free up system memory.
2. How to release RAM.
3. How to clear an SD card.

If it ends free place, then the first question that needs to be solved is how to clear the cache on Android. Deleting the cache frees up system memory quickly and for free. If you do not understand where the free space is going, clearing the cache will give the answer - the memory on the phone is running out due to the large volume of temporary files. To get rid of them, you need to clean your Android.

1. Open the settings, section "Applications".
2. Go to the settings of applications that create a lot of temporary files - Play Market, games, browser, instant messengers, social media clients. Don't forget about built-in applications like "Gallery". Even if you delete photos and videos from your phone, the information about them will remain in the cache.
3. Click "Clear Cache".

Manual clearing of internal memory Android devices not limited to deleting the application cache. To completely clear the memory of your Android phone, you need to examine the contents system folders... This can be done manually via file managers... Let's see how you can free up memory on Android by deleting temporary files through the File Manager.

You can also clean the folders of individual applications - VKontakte, Viber, WhatsApp. You won't clean the RAM on Android like that, but you will understand how to clear the internal memory of the phone. Plus, knowing how to clean your phone can help you get rid of viruses that periodically enter your system.

After deleting the cache and unnecessary files it will become clear where the memory of your Android phone or tablet has gone. The memory is gone because the system has accumulated a complete set of temporary data. The storage device cannot delete them on its own, hence braking and other problems arise. Knowing how to clear memory and freeing up system memory, the user extends the operating time of the device.

Using cleaning apps

We figured out how to independently clear the internal memory of Android. Now let's see how to completely clean your phone using dedicated apps. In the Play Market, you can find a large number of programs in Russian and English. Pay attention to the following applications:

• Clean Master.
• Cleaning wizard.
• History Eraser.
• Smart Booster.
• 1Tap Cleaner, etc.

They work according to the same principle: you launch the program, choose which files to delete, and wait for the optimization procedure to complete.

If you know how to manually clear memory on Android, then this will not be enough for complete removal unnecessary files. Using 2 methods, manual cleaning and optimization through applications, will help you figure out how to delete all unnecessary data that takes up space.

RAM cleaning

We figured out how to quickly clear the system memory on Android, but the question remains, how to clear the RAM? RAM on Android is also filled with data, the release from which allows you to answer the question of how to increase the speed of the phone.

Most cleaning programs are able to optimize RAM on Android and increase performance. If you do not understand where the performance has gone, then after the application is running to clear the RAM on Android, you can again use it in full.

On the Android platform, it gives out messages of insufficient memory or memory error, out of memory, and so on.

Many users face a problem when phone or tablet on Android base begins to be capricious. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

For example, the device has problems with the fact that at one stage or another of working with the gadget, the system issues messages about a failure, paying attention to problems with the "memory". This may be due to:

1st: Software glitch - i.e. the problem is crashing software

2nd: Hardware failure- i.e. the problem lies in the "hardware" (that is, the replacement or restoration of spare parts of the gadget is required)

However, do not rush to get upset - in 90% of cases with problems launching and running applications and the entire system smartphone a or Android tablet is to blame software glitch, which you can easily fix on your own.

Fixing a software glitch:

Method 1. Quite simple - go to "settings" find there « backup and reset " where you choose full reset settings with deletion of all data. Be careful, the use of this method is often effective, but it entails the deletion of all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if the problem persists after it, see Method 2.

Method 2.

Based on solving network communication and reception problems phone s and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a few of them, however, the fewer functions an application contains, the more, as a rule, it is effective. Best of all controls the functions of the system, corrects, and corrects everything possible mistakes settings and synchronization is small and easy to use, free utility for Android devices. Download app from Google play and you can see its additional options in the description. After installing the application, all that remains is to launch it. Further, from you, in principle, nothing else is required. The application will completely take over the control of the device's functions. (By the way, among other things, the gadget will start charging 20% ​​faster, and its performance will also significantly increase, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system works on 50% faster.)

• In addition, it is worth cleaning the system with NORMAL antivirus. Best of all, it copes with this task Kaspersky antivirus , which you can download. Unlike the "multi-cleaner", the software of "Kaspersky Lab" is paid, therefore, if you do not have the opportunity to install such protection, you can skip this step ...

Method 3.

Change of device software, or, as it is also called "Per firmware ".This method, as a rule, requires certain skills and is solved by contacting the Service Center. To independently carry out this task, you need to contact the manufacturer's website for your device, download the utilities and the firmware itself necessary for the firmware, and then reinstall it on your gadget.

If none of the methods has brought results, unfortunately, you will have to contact Service center for repair of your tablet a or smartphone a.

Missing "memory" on the tablet or phone. What to do if an Android phone or tablet displays messages such as insufficient memory, memory error, and so on.

Any smartphone user sooner or later faces one problem - there is not enough space in the memory of the Android device, how to fix it? After all, it would seem that there are devices with built-in memory of 16 GB and even more. But no matter how much it is, in the end it is always not enough. What's wrong? Where can it go and what to do with a crowded device?

The owner of the phone needs to know something - he will never have access to the full internal memory. This is due to the fact that part of this very memory is occupied operating system and all those applications, and sometimes games, that the manufacturer deemed it necessary to install by default. In this regard, the Android memory, which remains at the user's disposal, is always 2-3 GB less necessary for the normal functioning of the device. And therefore, if your memory is 4-8 GB, there is very little of it.

What affects the amount of free space and where does it go?

1. As it was already written above, first of all, part of the memory is lost due to the fact that the system itself uses it.
2. Further, it is filled with various applications that a person installs on his mobile phone or tablet.
3. Also, each program, and especially a game, gradually fills the space with a cache, which, although it speeds up loading in the future, often takes up a lot of space on the phone.
4. It so happens that the cache remote applications does not go anywhere, and therefore also becomes the cause of the problem, because usually new applications are placed on top, and old files are not cleaned up.
5. I can say with confidence that not all phone owners immediately worry when setting up their phone about where photos and videos will be stored - in the internal memory or on a flash drive.
6. And do not forget about various viruses that, being malicious, also steal free space quite well.

Ways to free memory

Basically, we find out that there is not enough memory on the device already when we are going to install a new application. At the same time, the error "Phone memory is full" or "Not enough free memory" pops up, Android offers to get rid of unnecessary and rarely used content.

The conscious owner of a smartphone always has installed utilities that can monitor the overflow of the device and offer appropriate solutions to this problem. It would be nice to independently monitor the state of the device's memory, for which it will be sufficient to go to the "Memory" section in the settings and see if the free space may run out.

Another signal that there is not enough memory can be considered a sudden braking of the phone, the response speed to user actions becomes much lower.

Removing unnecessary programs

This is possible using both the installed utilities and simply the Device Manager. To do this, just go into it, find the desired program or a game, click on it and then select "Delete." To the same method of reducing the clogged space, we also include stopping the work of built-in programs that are not removed without providing root rights... This is also done using the Dispatcher.

This video shows an example of the main ways to free up space on your device.

Clearing the cache

All the same Device Manager or special programs we delete the cache of any application, while not forgetting about the already deleted ones, the trace of which is still left. Just empty folders will be deleted immediately. Even if there is nothing there, but why are they on the gadget at all?
This should also include antivirus software, which, in the presence of pests, can also help free up space.

Transferring files to a USB flash drive or any other storage device

In the case when the memory is filled with a large amount of music, photos, videos and just pictures, you can free it by simply moving the files through the Explorer to a USB flash drive in your phone or to a computer. For Android users, there is an additional and very convenient function - Google Drive. Thanks to him, you can store information up to 15 GB in the "cloud", while deleting its copies from your device.

Some applications and games can also be moved to a removable memory card. True, this can be done not on all models and only with the help Android programs Assistant, or rather one of the functions - App2SD.

There is a place, but the error does not disappear

But what if the error about the lack of free space still pops up, although there is memory? You can try to fix the situation by deleting the Google Play Market cache. If necessary - and its updates (via Device Manager).
The last way is to delete the cache in Recovery mode. For this you need:

• turn off your phone or tablet;
• turn on, while holding the button to enter the mode (for different brands and models it is different, but often it is the power button + volume rocker + home button);
• select Wipe cache partition;
• if there is an Advanced item, then select it, and in it - Wipe dalvik cache.

In conclusion, I will say that there are many ways to increase the amount of free space on the device, but it is better to resort to the one in which you are confident. Just in order not to harm your device even more.

Articles and Life Hacks

Surely many users have faced a similar situation. What to do if phone memory disappears? Let's try to understand this failure using the example of platforms such as Windows Phone and Android.

Why this can happen on Windows Phone

• Let's start with the fact that the programs do not always correctly display the real amount of free memory in the mobile Windows device Phone. Also, don't forget about the cache and temporary files.

  Most likely, the memory is occupied by them, since the memory card can only contain photos and media files.

• Even after deleting some programs, some of them remain in the device's memory. Now that we surf the Internet, its size continues to shrink. What to do in this case?
• To begin with, you should reset your mobile device as this will restore it to its original state and also help in removing personal content.
• At the same time, it is recommended to take care of archiving all your data (including photos, music, game achievements, messages and applications) in advance. account Microsoft.
• We proceed to the reset. We go into the settings and go to the "Device Information" menu, where we select the "Reset settings" item.
  You can also get rid of unnecessary applications in the phone memory on Windows Phone using Shrink Storage.

  The program completely fills the internal storage, after which we reboot our device.

Why this can happen on Android

• The Android operating system is natively installed in system memory. In other words, the memory of our device is occupied by a variety of system files and folders.
• Everything preinstalled programs are located in the / system / app folder. Without most of them, our device will not be able to work normally, although there are some that we could easily do without (they are simply installed by default by the manufacturer).
• When we purchase a smartphone for Android, then we mistakenly believe that we have all the free space at our disposal.
• However, in fact, after the first launch, it is easy to make sure that our memory is completely filled with a variety of directories.
• At the moment, there are many special software for Android that will help you monitor the status of internal storage.
• If we are rooted, we can install the SystemCleanup app. For a reasonable fee, it allows you to transfer updated system programs, delete unnecessary items, back up and clear the cache.
