Price first, build quality, functionality, types and updates of software and other gadgets

If your phone or tablet running Android 6.0 or 7 Nougat has a memory card slot, then you can use a MicroSD memory card as the internal memory of your device, this feature first appeared in Android 6.0 Marshm.

Note: When using a memory card in this way, it cannot be used in other devices - i.e. It will be possible to remove it and connect it via a card reader to the computer (more precisely, to read the data) only after complete formatting.

Using an SD memory card as internal memory

Before you start setting up, transfer all important data from your memory card somewhere: it will be completely formatted during the process.

Further actions will look like this (instead of the first two points, you can click on “ Tune" in the notification that a new SD card has been detected if you have just installed it and such a notification is displayed):

1. Go to Settings - Storage and USB drives and click on the item " SD card"(On some devices, the storage settings item may be located in the " Additionally", for example, on ZTE).

2. In the menu (button at the top right) select " Tune" If the menu contains the item “ Inner memory", immediately click on it and skip step 3.

3. Click " Inner memory».

4. Read the warning that all data on the card will be erased before it can be used as internal storage, tap " Clear and Format».

5. Wait until the formatting process is completed.

6. If at the end of the process you see the message “ SD card is slow", this indicates that you are using a Class 4, 6 or similar memory card - i.e. really slow. It can be used as internal memory, but this will affect the speed of your Android phone or tablet (such memory cards can work up to 10 times slower than regular internal memory). We recommend using UHS Speed ​​Class 3 (U3) memory cards.

7. After formatting, you will be prompted to transfer data to a new device, select " Transfer now"(until the transfer, the process is not considered completed).

8. Click " Ready».

9. It is recommended that immediately after formatting the card as internal memory, restart your phone or tablet - press and hold the power button, then select " Reboot", and if there is none - " Power off" or " Switch off", and after turning it off, turn the device on again.

This completes the process: if you go to the parameters “ Storage and USB drives", then you will see that the space occupied in the internal memory has decreased, on the memory card it has increased, and the total amount of memory has also increased.

However, the function of using an SD card as internal memory in Android 6 and 7 has some features that may make using this feature impractical.

Features of the memory card working as internal Android memory

It can be assumed that when a memory card size M is added to Android's internal memory of N, the total available internal memory should become N+M. Moreover, approximately this is also displayed in the information about the device’s storage, but in fact everything works somewhat differently:

  • Everything that is possible (with the exception of some applications, system updates) will be placed on the internal memory located on the SD card, without providing a choice.
  • When connecting an Android device to a computer, in this case you will “ see" and only have access to the internal memory on the card. It's the same in file managers on the device itself.

As a result, after the moment when the SD memory card began to be used as internal memory, the user does not have access to the “real” internal memory, and if we assume that the device’s own internal memory was larger than MicroSD memory, then the amount of available internal memory after of the described actions will not increase, but decrease.

Formatting a memory card for use as internal storage in ADB

For Android devices where the function is not available, for example, on the Samsung Galaxy S7, it is possible to format the SD card as internal memory using ADB Shell.

Since this method can potentially lead to problems with the phone (and may not work on every device), I will skip the details on installing, enabling USB debugging and running in the adb folder (If you don’t know how to do this, then perhaps It’s better not to take it. And if you take it, it’s at your own peril and risk).

The necessary commands themselves will look like this (the memory card must be connected):

  • adb shell
  • sm list-disks ( As a result of executing this command, pay attention to the issued disk identifier of the form disk:NNN,NN - it will be required in the next command)
  • sm partition disk:NNN,NN private

Once formatting is complete, exit the adb shell, and on your phone, in the storage options, open the item “ SD card", click on the menu button at the top right and click " Transfer data"(this is required, otherwise the phone's internal memory will continue to be used). Once the transfer is complete, the process can be considered complete.

How to restore normal functioning of a memory card

If you decide to disconnect the memory card from the internal memory, this is easy to do - transfer all important data from it, then go to the SD card settings, just like in the first method.

Select " Portable media» and follow the instructions to format the memory card.



Installing applications on a memory card is required by almost every owner of an Android device, especially if the internal storage is designed for a small number of files. Regardless of the purpose for which you use your device - for work, study, entertainment, games, the allocated memory capacity may not be enough. If you are interested in how to install an application on a memory card in Android, then you can use two methods - system functions or special utilities. Which we will now look into in more detail.

Android system capabilities

The Android platform, starting with version 2.2, provides a system function for moving content from external memory to a card. This feature does not always work, since its functionality also depends on the properties of each specific program or game.

How to install applications on a memory card in Android:

1 . It is assumed that you already have apk downloaded and installed on your device, which now needs to be moved to SD to free up memory. Open your device settings and go to the applications tab.

2 . The new window should contain several items - downloaded, located on the SD card and all programs. We need the first point.

3 . The downloaded section contains all the software that you downloaded and installed yourself. Now you have to work with all the programs displayed in the list separately, since it will not be possible to transfer all of them at once.

4 . To move applications to the memory card, select any of them in the list and click on it. The display will show all the information about it, including the required amount of memory, access to data and other information.

5 . If a certain program has a function for installing on external storage, then the “ Transfer to SD" will be active - click on it and the moving operation will start.

6 . If the button is not active, then the system tools are powerless in this case - you will have to use third-party utilities.

It is worth noting that the above instructions apply exclusively up to platform version 4.2, including it, but how to save applications to a memory card in Android if the device runs on newer versions of the platform? These include the following OS: 4.4, 5.0, 5.1, 6.0.

In such a situation, you will have to find an additional utility. It may also be necessary to have root rights. However, in version 4.4, in some cases you can still do without additional programs, but a lot depends on the model of the mobile device. For example, Sony made sure that the devices included installation of programs on the memory card in Android directly without additional applications and utilities.

Using third party applications

There are quite a lot of special utilities that solve the problem of installing software on SD, but only a few of them can effectively help the user. The most interesting applications for transferring applications to an SD card should be noted:

  • App 2 SD
  • Link 2 SD
  • Total Commander

App 2 SD

This is one of the most popular utilities among Android owners, which greatly simplifies working with content. The latest version of the program has a redesigned and improved design.

Main functions:

  • moving programs;
  • software management;
  • hiding programs.

Directly in the utility, all content on your device is divided into two categories - that which is already located on SD, and that which can be moved there. On Android, transferring applications to a memory card is possible for one selected program or all existing software. If you install a program that can be moved, App 2 SD will notify you about it.

Every owner of an Android device is extremely dissatisfied with the presence of a large number of unnecessary system applications on his device. There is no way to get rid of them in the usual way - to remove them you need to have root rights. However, you may accidentally touch important files, which may cause the device to malfunction. There is a way out of this situation, thanks to the functionality of the presented program. App 2 SD can hide system content, due to which it will not load the system.
As for managing downloaded applications, thanks to App 2 SD you can remove programs (while performing a full system scan for unnecessary data), clear data and cache.

Link 2 SD

The program is designed as a functional application manager, with its help you can not only transfer content to storage, but also clear cache files. The program has the usual software installation function, as well as moving with advanced functionality, which requires two partitions on SD and .
Link 2 SD is suitable for experienced users who understand the features of file systems and SD partitions. Main functions:

  • moving apk., lib., dex files. to SD and back;
  • automatic installation to SD;
  • transfer even of content that does not provide this feature;
  • choosing a location to install new applications;
  • notifications about the possibility of transfer;
  • “freezing” embedded content;
  • clearing cache and data;
  • converting user programs into built-in ones.

Total Commander

Total Commander– a well-known manager among Android and PC owners. The manager provides a huge number of functions that are designed to manage various data in the system. Main functions:

  • moving, copying, renaming, deleting files/folders;
  • data transfer via Bluetooth;
  • selecting and sorting files;
  • built-in archiver;
  • text editor;
  • search for files and data;
  • audio and video player;
  • support for functions provided by root rights;
  • changing file properties, etc.

The functionality does not provide a special option for installing applications to external storage, however, it is thanks to the support root rights it becomes available.

Conclusion

Now you know how to transfer applications to a memory card, what may be required for this, what difficulties users encounter most often. It should be noted that this function is considered very useful, since over time the amount of available memory in the device becomes less and less, and you don’t want to get rid of important programs. Unfortunately, automatic installation of programs on SD is not possible, so after each installation you will have to move the content to external storage yourself.



Hello everyone! Your phone doesn't see the memory card? Was there important data on the flash drive? In this article I will tell you why the memory card may not be visible on the phone, and I will also share my methods for restoring a flash drive.

At the same time, I will say right away that the accessory could simply break, but in 50% of cases the fault is a software glitch, which you can fix yourself without contacting a specialized cell phone repair service.

The instructions and tips described below are suitable for all phones, including older models that cannot be classified as “smartphones”. This topic is especially relevant for those users who still have important data on their phone. Sometimes it is impossible to restore the functionality of the flash drive in the phone itself, but it is possible to transfer data to a computer using a card reader.

After studying today's article, the user will learn:

1. Why flash drives stop working.

2. How to check the status of the memory card.

3. How to format a flash drive on a computer.

4. Formatting the memory card using phone functions.

5. Memory card malfunctions and their causes

Important! If you are installing a flash drive for the first time, then the reason for its lack of operation may be the capacity of this drive. This applies to older phone models that are not designed for large memory cards.

The phone does not see the memory card

Now study the main malfunctions and possible solutions:

— The file system is damaged – the memory card can be restored by formatting (the most common malfunction);

— The contact of the drive has come loose in the phone’s flash reader – you need to insert the flash drive firmly and reboot the phone;

— The flash reader has failed, so the phone does not see the memory card - repairs at a service center will help here;

— The flash drive burned out - it, of course, can no longer be restored. Although you can still try to recover data, here is one of my articles in which I told you how to recover data from a burnt flash drive.

So let's continue. Now you need to check what exactly happened to the memory card. First of all, reboot your phone; sometimes such a simple action is enough to fix an error in the file system of the drive. Did not help? Remove the battery (if the flash reader is located behind the battery and not on the side) and check whether the flash drive fits tightly to the contacts.

The next step is to check the flash drive on another device. The easiest way to do this is with a card reader: just place a flash drive in it and connect it to the computer. If there is no reader, then insert the flash drive into another phone.

If the memory card is readable on another device, then the problem lies in your device. To find out more, you need to take it in for repairs. Sometimes it's just a bug in the software, and sometimes it's a broken contact. If the memory card is not visible on other devices, then it is either burned out or its file system is damaged. In the second case, formatting will help. Also, in some cases, you can repair a memory card using simple commands, which were described in this article:

ATTENTION! When formatting, all data will be deleted from the flash drive. If you are not sure that the cause was a software glitch, then it is better to immediately take the memory card to be checked. For those who want to try to “reanimate” a flash drive, I have prepared two simple instructions. If your phone still does not see the memory card, then read on.

Formatting a flash drive on a computer: step-by-step instructions

You can format a flash drive on a computer using a card reader. If it is not there, then go to the second instruction. And now on topic:

1. You need to place the flash drive in the card reader, and then insert it into the corresponding slot in the computer or laptop.

2. Now we wait for the flash drive to automatically launch on the computer. If this does not happen, then go to “My Computer” - there you will see a new device (if the flash drive is not burned out).

3. Right-click on the mouse icon and select “Format” from the context menu.

4. After this, the formatting menu will appear. You need to select the file system of the flash drive: “NTFS” or “FAT”. By default, the FAT format is selected for almost all cards, but if this formatting does not bring results, then try selecting NTFS.

Check that everything looks like this screenshot:

Now click on the “Start” button and wait for the process to complete.

Now you can insert the flash drive into your smartphone and check whether it works or not. If the problem persists, then you should try the second instruction. Sometimes the card is not readable after formatting on the phone due to the partitions that Windows creates when formatting.

Format a flash drive in your phone

The phone sees the memory card, but you still can’t open it? Then let's format it right here. We insert the drive, check the contacts and go to the memory settings. On Android phones, you will find this option in the memory options. In this section, you need to click on the “Disable card” or “Eject” button, as shown in the screenshot:

Now click the “Clear memory card” button. The process will take no more than a minute. After this, you need to select the “Connect SD card” menu item. In addition, I recommend that you watch the following video:

It is worth considering that depending on the Android firmware version, the path to this function may differ. Formatting flash drives in gadgets with another operating system is the same process - you need to find the “Memory Settings” section.

So, to summarize today’s article - “The phone does not see the memory card”, it will be necessary to add that if formatting does not help, then you can immediately take the memory card to a service center or buy a new drive. I hope that my article helped you recover your flash drive. It's especially good if you were able to do it without formatting.

Quite often, owners of Android devices encounter an unpleasant problem when the phone has a MicroSD. What to do in this case, what methods to solve the problem to apply? First you need to determine the root cause and analyze possible situations.

Why doesn't my phone see the MicroSD flash drive?

It goes without saying that there can be any number of reasons for such failures. Here there are software failures of the system itself, and a banal lack of contact between the memory card and the card reader, and violations in the file system of the USB drive, and even physical damage.

However, the situation can look two ways. On the one hand, this may concern a new card that you just purchased, but on the other hand, the problem may be that over time the phone has stopped seeing the MicroSD flash drive. What to do in this case will now be considered.

By the way, the issue of compatibility between the card and the phone itself will not be discussed here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards. Moreover, it may be that the card’s memory is larger than what is stated in the device’s support. So in this case the card will not be detected.

The phone does not see the MicroSD flash drive: what to do first?

If problems arise with an already installed memory card, no matter how it sounds, the cause may be ordinary contamination of the device, say, dust. Agree, not every user constantly cleans their phone.

Here the solution is the simplest: remove the card from the phone, wipe the contacts on the flash drive itself and on the card reader, and then reinsert it. By the way, this option is also suitable for new cards. Well, you never know, the contacts simply didn’t work. Therefore, do not rush to run to the service center or throw away the card you just purchased.

Using Recovery Mode

If simple manipulations with contacts do not help, you can use the special Recovery mode provided in any Android device, although you can first perform a normal reboot.

To access the mode we need, we use the simultaneous holding of the power and volume down buttons. This is the most common option. But, in principle, each manufacturer can prescribe a different combination. That's not the point. After the device starts, a special service menu will appear, where you need to select the Wipe cache partition item, after which you simply reboot the device. If even after this the phone does not see MicroSD, we move on to more effective measures. They will be radically different from the previous steps.

Problems with the MicroSD card on the computer: what can you do?

Well, firstly, it is worth noting a generally exceptional situation when both the computer and the phone do not see the MicroSD flash drive. This is already worse. This problem is almost never fixed on a phone.

First, you should insert the card into another device or computer and make sure it works. If it is detected, the problem is only with the phone or the drive names on the computer. If the card is not detected, the problem is either with the file system or with the memory card itself.

So, first you should use which is called quickly enough in Windows. You can use the Win + X combination and then select Disk Management, or enter the diskmgmt.msc command in the Run menu bar field.

This method is good because absolutely all connected disk devices, even unformatted ones, will be displayed in the main window. It is quite possible that the letter of the removable card, for example “F”, matches the designation of the optical drive. Right-click on the map and select the command to change the letter.

However, after such an operation, a situation may also arise when the phone does not see the MicroSD flash drive. What to do, since it is already recognized on the computer? The easiest way to correct the situation is to partially or completely format the media. However, complete formatting with deleting all data and re-creating the file system still looks preferable.

It can be produced either here or from the standard “Explorer”. In both cases, right-click calls up where and selects the formatting line. In the new window, you need to uncheck quick formatting, and then specify creation. But, in principle, FAT32 is installed by the system by default. Now all that remains is to confirm the start of the process and wait for it to finish. After this, you can safely insert the card into your phone.

Restoring the MicroSD card

Now a few words about another situation when the phone does not see the MicroSD flash drive. What to do if it is detected on the computer, but not on the mobile gadget?

First, you should again connect the card to your computer or laptop and perform a standard check of the device for errors. We use the same “Explorer” and then go to the properties menu. There we select the service section and with the obligatory indication of automatic error correction. Also, although not required, you can use a surface test with automatic recovery of bad sectors.

Another option involves correcting access to the memory card specifically on computer terminals, as well as normalizing parameters and system registry keys in the HKLM branch. You should find the SYSTEM folder in the directory tree, in which the StorageDevicePolicies directory is located. On the right side, the defining parameter must be assigned a zero value (usually 0x00000000(0)). After this, the problem should disappear.

Finally, if the card has minor physical damage, which is usually associated with malfunctions of the microcontroller, you will have to look for special utilities for formatting, having first learned the VID and PID parameters. This can also be done using special programs, such as USBIDCheck, or by disassembling the card (where the data is indicated on the internal chip).

Then, for each card of a certain manufacturer, a program is downloaded from the Internet in accordance with known parameters, after which formatting is performed.

Conclusion

If for some reason the removable device is not detected, there is no need to panic. First you need to determine the root cause of the failure. As practice shows, any of the proposed methods helps solve the problem. If we talk specifically about phones, here, it’s more likely that cleaning the device from dirt, formatting the card, or restoring functionality, as described in the last version, would be suitable.

By the way, the issue of compatibility between the card and the phone itself was not considered here. This is worth paying attention to separately, since outdated gadgets are not able to detect the latest generation SD cards.
