Where is the memory card in the phone?

To install a memory card, you need to find a slot for it. In modern smartphones, it sits in the SIM tray. You can remove the tray with a paper clip.

How can I transfer applications to a USB flash drive

To begin with, we will transfer the already installed applications from the phone’s memory to the flash drive, and then we will try to make the programs automatically install on the SD card.

Memory setting

Let’s go back to system tools again. On Android, you can specify the SD card as the default install location for apps. Again, this does not always work.

Try the following anyway:

  • While in the settings, open the “Memory” section.
  • Click on “Preferred Installation Location” and select “SD Card”.
  • You can also assign storage to save other files by designating the SD card as “Default memory”.

The arrangement of elements on your device may differ from the examples shown. Therefore, if you have any questions or fail to do all the steps described in this article, write about it in the comments below. We will definitely help you to solve the problem.

Switching internal memory to external

There are two ways to replace the memory in the phone, the first is carried out by system means, and for the second you will need any file manager and ROOT rights.

We use Clean Master to transfer data to a memory card

As noted above, this method is analogous to the previous version of transferring to an SD card. We suggest that you immediately start reviewing the instructions:

  • Tap on the “App Manager” icon;
  • Now click on the “Move to SD card” button;
  • Wait for the operation to complete.

Done! The memory on the device itself is freed. By the way, if we compare the two methods already presented, then we advise you to choose the second one. using the Clean Master application. So you will spend significantly less time due to the fact that you can select several games and programs at once.

Third-party programs to move

Operations with the programs listed below require superuser rights. Be careful: receiving them will void your device warranty.

Make sure your SD card type is at least C4 before transferring programs, otherwise the transfer will take a long time.

Replacing the internal memory with an SD card

This method will trick the Android system into treating the SD card as its system memory. To do this, you need root rights and a file manager, for example, Total Commander.

All the actions described below you carry out at your own peril and risk. It is highly recommended to make a backup of the entire device in advance.

  • Download Total Commander, launch it and give it ROOT rights.
  • At the root of the system, open the folder “etc”.
  • Find the file “vold.fstab”, click on it and select the Edit button.
  • A notepad with many lines will open. We need lines starting with the words “dev_mount”.
  • There will be two such lines, one with extsd, the other with sdcard. The bottom line is to swap the lines after the word “mnt /”: write sdcard instead of extsd and vice versa.
  • Everyone, save your document and restart your phone.

How to switch phone memory to memory card?

How to switch memory to card on Android. By default, all applications are installed on the internal memory of the Android device. It is also used to store their cache. But even the memory of modern smartphones is sometimes not enough to load all the necessary software. It’s good that there are memory cards with enough capacity for this. How to use them to unload main memory, we will consider further.

Risks and what you need to know

Replacing the internal Android memory with a memory card occurs only if you have installed root rights (no root, the method does not work)! For those who do not know what Root is and how to get:

  • What is Root Android?
  • How to Root Android?

In addition, you must know the structure of the Android file system.

Memory substitution is possible only if your Android device has a system file vold.fstab along the path / system / etc, if you do not have one, then this method is unfortunately not for you! Use alternative methods (.). Also, if Android does not have its own memory, then this article is also not for you. The article is mostly for devices with a Mediatek (MTK) or Rockchip processor.

Since the system file will be edited, there is a risk that you may make a mistake and the device will not boot, in order to fix this, you need to reflash the device, and the memory card may fail and you will face the same problem, the firmware will also help.

With a replacement internal memory to a memory card, the latter has a very severe life cycle (due to frequent read / write), and the speed of Android may also drop if the class of the MicroSD card is very low.

Cache transfer for Android 4.0 versions

Google has added the ability to transfer the app and cache to an Android memory card for devices running the 4.0 version of the system. This is done as follows:

  • We go to the settings of the smartphone / tablet.
  • Next, go to the Applications tab.
  • In the window that appears, look for the desired program or game and click on it.
  • In the description of the program / game there should be a sub-item “Memory”, which indicates the occupied space. And just below there are 2 buttons: “Move to SD card” and “Erase data”.
  • We select the transfer key and wait for the end of the process.
  • If the operation is successful, the button should change to “Move to phone / tablet”. This means that the transfer of the application to the Android memory card was completed without errors.

It should be noted that this method does not require ROOT rights, but it is not suitable for all applications. So, if there are no necessary buttons in the description of the application, you should not be upset, because this was the easiest way. For even greater relief, you can use the Apps 2 SD utility (Move app 2 SD) or the like, where all applications are conveniently structured, which speeds up the search for the ones you need.

ATTENTION! The methods presented below can be applied only on devices with ROOT rights. All further operations are done at your own peril and risk, no one gives a 100% guarantee that in case of failure you will not receive a brick. Also, we do not accept any responsibility for the loss of personal data.

Changing the contents of the Vold.fstab file

The first of the described methods involves changing the contents of the system settings file “Vold.fstab”. After making these changes, Android OS will read your SD card as the device’s internal memory, but note that a number of previously installed applications may stop working.

It is important to know that this method only works on rooted devices with Android OS lower (!) Than version 4.4.2 installed. In Android OS versions 4.4.2 and higher, the specified file, most likely, you simply will not find.

switch, samsung, memory, flash

Also, keep in mind that a mistake in the implementation of this method (in particular, adding extra characters to the required lines) can affect the performance of your device in the most sad way. Therefore, carefully weigh the possible risks, and if, nevertheless, you have made a decision, then proceed with its implementation.

So, to implement this method, do the following:

  • Start any file manager (for example, the popular “Total Commander”);
  • Go to the root of the filesystem;
  • Find the “etc” folder there and go to it;
  • Find the vold.fstab file there, tap on it, and switch to its editing mode (in “Total Commander” run “Totalcmd-editor”);

Switch to the editing mode of the file “Vold.fstab”

  • Within this file, there are many lines starting with the “#” character. You need to find lines that start not with a hash, but with a combination of characters “dev_mount”. Usually these will be two lines arranged in a column, one of them will point to internal memory, the other to external memory.
    • dev_mount sdcard / storage / sdcard0 emmc @ xxxxxx
    • dev_mount sdcard2 / storage / sdcard1 auto / xxxxxx

    To make the necessary changes, we need to change the path in the indicated lines in places, that is, in other words, instead of 0, put 1 in the first line, and in the second, instead of 1, put 0.

    After the changes, these lines will look like:

    • dev_mount sdcard / storage / sdcard1 emmc @ xxxxxx
    • dev_mount sdcard2 / storage / sdcard0 auto / xxxxx

    Save the changes you made and then reboot the gadget.

    Another option is how to make a memory card the main one on Android:

    Good to know: What is Normal Boot on Android

    We use OS settings Android 6.0 and higher

    In addition to the first method, in which I examined how to switch the phone memory to a memory card, there is another method that works only on OS settings Android 6.0 (Marshmallow) or higher, and allows you to use the SD card as the main one for saving files and working with them To implement it, I recommend making a copy of the data from your SD card (if any), since this card will be formatted by the system.

    • Connect SD card to your device;
    • Go to the gadget settings, then to “Storage and USB drives”;
    • Tap on the item “SD card”;

    Tap on the item “SD card”

    In the menu on the right, click on “Settings”. “Internal memory”. “Clear and format”;

    Select “Clear and Format” to format your card

  • After the end of the formatting process, a message about slow memory may appear (usually in a situation if a low grade SD card is used);
  • A message will appear about the transfer to a new device, activate the item “Transfer now”. “Finish”.
  • Interesting: Talkback what is this program on Android

    In this article, I examined the options for how to make an SD card the main memory on Android. It is important to bear in mind that these methods do not always work. the first requires ROOT rights and Android OS lower than 4.4.2., And the second works with Android 6.0 and higher (while there are a number of modern devices, for example “LG G5”, on which the implementation of the last method is impossible for internal reasons). Also note that the implementation of these methods is carried out by you at your own peril and risk, and it is hardly possible to guarantee a 100%.percentage result in this case.

    Replacing internal memory with external

    And this method allows you to trick Android into treating the memory card as system memory. You will need any file manager from the toolkit. For example, Root Explorer will be used.

    Attention! You do the procedure described below at your own peril and risk. There is always a chance that this will cause problems with Android, which can only be fixed by flashing.

    At the root of the system, open the “etc” folder. To do this, open your file manager.

    Find the file “vold.fstab” and open it with a text editor.

    Among all the text, look for 2 lines starting with “dev_mount” without a leading pound. They should be followed by the following values:

    • “Sdcard / mnt / sdcard”;
    • “Extsd / mnt / extsd”.

    You need to swap the words after “mnt /” to make it look like this:

    • “Sdcard / mnt / extsd”;
    • “Extsd / mnt / sdcard”.

    Different devices may have different designations after “mnt /”: “sdcard”, “sdcard0”, “sdcard1”, “sdcard2”. The main thing is to swap them.

    Save changes and restart your smartphone.

    As for the file manager, it should be said that not all such programs allow you to see the aforementioned files. We recommend using ES File Explorer.

    Transferring the cache to a USB flash drive

    This method is useful for users who like games with a large cache. Now many large projects (for example, a series of games Asphalt, FIFA, Grand Theft Auto) take up several gigabytes. The same goes for nautical charts. Not all devices can boast of this amount of internal memory, which is why FolderMount comes to the rescue. It allows you to create virtual folders so that the system still thinks that the application data is in internal memory, although in fact all the files are located on the USB flash drive.

    • Install FolderMount.
    • Launch and grant Superuser rights.
    • Open the pull-down menu on the left side of the screen.
    • Go to the “Application Analyzer”, look for the desired game and click on it.
    • In the window that opens, we see the volume that the application data and its cache take separately.
    • Click the “Create Pair” button opposite the cache size.
    • Answer the question “Yes” and click the checkmark at the top of the screen, after that you must again answer “Yes”.
    • In the notification line, you can see the process of transferring files.
    • As soon as the transfer is completed (reaches 100%), open the pull-out menu again and select “List of pairs”.
    • It remains only to press the switch opposite the name of the game that you transferred.

    Replacing internal memory with external

    This method allows you to deceive the system, i.e. Android will read the SD card as the device’s memory. One of the main advantages is the fact that all applications will be automatically installed on the USB stick. Ideal for devices with very little internal memory. To implement it, you need a file manager, it is best to use Total Commander. The meaning of the method is to swap the paths to the device memory and flash drive.

    • Install Total Commander.
    • Launch and give Superuser rights.
    • Go to the “File system root”.
    • Further the folder “etc”, and in it find the file “vold.fstab”.
  • Click on the file, then “Edit”.
  • The file contains many lines that start with # (pound symbol). But we need a line that starts with the words “dev_mount” and without the (.) Pound sign at the beginning.
    There should be 2 such lines: the first denotes internal memory, the second. external.
    For example, if your lines are:
    dev_mount sdcard / mnt / sdcard
    dev_mount extsd / mnt / extsd
    Then they should become:
    dev_mount sdcard / mnt / extsd
    dev_mount extsd / mnt / sdcard
    That is, the most important thing is to swap the words after / mnt /.
  • You don’t need to change anything else, press the “Save” button (floppy disk icon).
  • Reboot the device.
  • A small amount of internal memory on cheap Android smartphones and tablets, the main problem is the inability to install applications in such cases, replacing the Android internal memory with a memory card can help you.

    For those who did not understand from the title what this article is about: suppose you have 400 MB of internal Android memory, which is very small (about 12-20 installed applications), then you might think to take and replace the main memory with a memory card.

    Full transfer of Android applications to SD memory card

    An attentive user could have noticed that Link2SD and other similar utilities have an interesting “Send” function. With its help, not individual parts of the program are transferred, as in the previous paragraphs, but absolutely all data. In this case, the program will consider that it works in the internal memory of the device, which for some of them is an important condition for normal operation.
    To implement this method, the SD card must be “split” into two sections, after which all data will be deleted from it, therefore, be careful and make a backup copy of important information.
    Partitions on a memory card can be done as on a computer using programs such as Paragon Hard Disk Manager 12 Server or MiniTool Partition Wizard Home Edition. But this is a rather laborious process, and therefore we will do everything right on the smartphone using AParted (SD card Partition).

    • Download and install the utility.
    • In the device settings, we find the “Memory” section, where we press “Extract SD”.
    • Go directly to AParted and in the first Create tab, double-click ADD.
    • In Part 1 we leave Fat32, and in Part 2 we choose ext2 or any other format, if you know what they are for at all.
  • We make sure that the Format field is checked and select the required memory size for each of the sections. At the same time, Part 1 will remain our standard “flash drive”, but applications will refer to Part 2.
  • Click APPLY and confirm the action.
  • Patiently waiting for the end of the process.
  • Now applications and games can be safely linked to the second section of the memory card using the corresponding Link2SD function or its equivalent.
