If your device does not have enough internal memory, can use SD card as internal storage for your android phone. This feature, called Adoptable Storage, allows the Android OS to format external storage media as permanent internal storage. The information on the installed SD-card is encrypted and cannot be further used on another device.
SD Card is a very convenient option for storing photos, songs and videos. Even if you have a large amount of internal memory on your Android smartphone, you may always need a large chunk of memory to store long videos captured by the camera. high resolution your phone.
It's important to know
There is one drawback, the LED chip can lag when recording high definition video.
Android by default installs applications in the internal memory and only occasionally uploads data to the SD card. Thus, you are deprived of installing any additional applications if your phone lacks internal storage, for example, in the case of budget devices on Android One.
What is cumulative storage?
Accumulative storage is the main memory of your smartphone, but if necessary, it can be expanded by using an SD card.
This on Android is called Adoptable Storage. This will allow you to use the removable microSD card installed on your Android phone as your primary storage. Thus, you can easily solve the problem of how to make an SD card the main memory on Android and overcome the lack of space if the phone has a small internal volume.
Features of using the map as the main storage
There are some important things to consider in this procedure.

When using a storage device, be it an SD-flash drive or a USB-drive, it is important to remember what format this device is in and whether it is supported by the Android operating system, and there are four types of main file formats: FAT32 or exFAT, ext4 or f2fs.
How to change phone memory to android memory card? The question is not entirely correct, it is impossible to completely replace it, you can only sort of "build up" the additional volume.
Using your SD-card as your primary storage device can be a great solution for music lovers and TV shows on their way to work or on a long trip. But, as often happens, memory expansion always depends on the cost of the required device, after all, they differ both in speed and in volume, as well as in the adaptable function of storing information. Here are some of the nuances that can be viewed from different angles - both negatively and positively:
- SD cards are slow. This is the painful reality of today's tiny memory chips. While they can store tons of data, they are slower than phone storage and have a limited number of read-write cycles.
- Non-returnable integration into the operating system. Using the Adoptable Storage feature, the Android operating system encrypts the external SD card used as internal storage, so it binds to a specific device, without the possibility of further use on another smartphone. The key used to encrypt data on the SD card is stored in the main memory Android devices... Thus, it is impossible to dismantle the received storage on another phone due to its encrypted nature of the data (you can remove the card, but it will not be detected on the other phone).
- Not all programs can be installed. Almost Android can install almost all applications on its internal storage. However, this also depends on the consent of the application developer. He has the right to enable or disable support for the accepted repository in the application by adding appropriate attributes to the code of the downloaded program.
- Place the SD card on Android phone and wait for it to be defined or displayed in.
- Now open "Settings".
- Scroll down and go to the "Storage" section.
- Tap the name of your SD card.
- Tap the three vertical dots in the upper right corner of the screen.
- Click on "Storage Settings".
- Select the "as internal option" format.
It's important to know
Using SD cards as permanent storage will require more frequent read / write operations, which will degrade its performance over time, and in the worst case can lead to complete data loss. It will be especially offensive if there are important documents or expensive for memory photos or unique videos.
Before changing the phone memory to a memory card, your Android will perform a performance test of the SD card to make sure that it is fast enough and can meet the parameters for use as a main storage.
However, you can remove the external removable storage from your device and put it back into simple flash drive mode. The device will remember what is on this card in order to restore the settings when the accepted device is connected later. Thus, you can also use another storage device.
It's important to know
Always make sure that you do not remove the default SD card during the unmounting procedure, otherwise the storage medium may be damaged.
How to use SD card as internal storage on Android?
How to replace internal memory phone to an external sd card on android? Configuring your SD card to act as internal storage on Android is essentially a fairly straightforward process. There is nothing complicated in this, and you will see for yourself later on.
note
Please note that your SD card will be formatted during the process. Do not forget to back up your data by temporarily transferring it to the main unit of the phone, desktop computer, laptop or other smart device.
It is possible that the Adoptable Storage function is not supported by your device, even if the smartphone is running Android 6.0 or higher (it also happens, it all depends on the model and brand of the smartphone). The device manufacturer may have disabled this feature. However, there are command line techniques that force the use of a flash drive for storing data.
The following are the basic steps for formatting.
On the next screen, you have one last chance to decide for yourself if you want to change your mind.
Articles and Life Hacks
A common question, how to enable a memory card on the phone, interests many owners mobile devices on which free storage space useful information turns out to be very small.
Installing a memory card
- In order to install a memory card on the device, you will need to find a connection slot for this part on the phone itself. As a rule, it is located on the side of the gadget panel.
- Then the selected map is loaded here, which is suitable for the user in terms of volume.
- It is necessary to check how thoroughly the part is fixed in the slot. If all is well, an expressive click will be heard.
As a rule, nothing else needs to be done to detect the memory card by the telephone. However, there may be exceptions.
- It is also recommended to immediately change the settings of the gadget and mark the saving of information not to the built-in, "native" memory of the mobile phone, but to the loaded memory card.
What to do if the memory card is not detected
Reading information from a working memory card is often a real problem. What if, as a USB device, it is not visible and is not displayed at all on the device?
- If such an add-on is installed on the mobile phone, then the difficulties can be solved by using a card reader. This device is a true universal adapter.
His work is focused just on reading information from various memory cards.
- Card readers are different: multi-format, built-in and single format. That is why, when choosing it, you should pay attention to the use of the memory card itself in the phone: Micro SD, Mini SD or SD.
- To turn on the memory card, you first need to connect the card reader itself to the PC. On the phone, you need to close all applications and folders.
As a rule, after data manipulation, the card begins to interact perfectly with the phone itself. However, for safety reasons, it is still recommended to transfer data from a mobile device to a PC.
Among other tips, it is worth noting that many experts recommend purchasing the largest memory card in terms of volume.
Many people want to know how to install applications on an SD card in Android devices. If the user has a phone or tablet with a small amount of permanent memory and RAM, then he probably often uninstalls programs to free up space. But there is a way to increase the storage capacity by using an SD card.

Default games and Android apps installed on the built-in storage of your smartphone, which may be too small. If there is an SD, then you can make it so that some programs are installed there by default, thereby freeing up space for more information. Under certain conditions, almost any installed program can be transferred to a removable flash drive.
How to install an app to an Android SD card? There are several different ways to accomplish this operation. The choice of the correct method depends on the version of the operating system and the data that needs to be moved. In Android 6.0 Marshmallow settings, you can adapt SD as built-in memory by automatically installing allowed games and software to removable storage.
Some smartphones without a new operating system allow you to manually move the application to the memory card, but only if the developer allows it. An alternative way to transfer programs is to use the Link2SD application.
It should be noted that programs launched from the card are likely to run slower than those in the built-in memory.
That is why you can transfer applications to an external flash drive only in case of extreme need. It is recommended to use this method whenever possible for programs that do not need high speed for normal operation.
How to adapt an SD card to internal memory
Traditionally, SD on Android has served as portable storage. This means you can store videos, music and photos on them for use on your smartphone. SD can be connected to a computer for two-way file transfer. When used as a portable storage device, the card can be removed without compromising functionality.

How do I install applications to a memory card? Android 6.0 Marshmallow system allows you to use SD as built-in storage, making it an integral part of your smartphone. If you accept a removable flash drive as the main storage, then by default the new software will be installed on it. If desired, the user can move the program back to the built-in memory.
If an external drive is used as the main storage, then it cannot be removed without affecting the functionality of the gadget. In this case, the card cannot be used on other devices (including a PC). The SD card is formatted as a local EXT4 drive, encoded with 128-bit AES encryption and mounted as part of the system. When Marshmallow accepts the drive, it will only work with that drive.

Now how to set up an SD card. Be sure to back up your data and save it on your computer before using the USB flash drive as internal storage. The onboarding process will delete all data. It is possible to return data to SD after the drive has been adopted as built-in storage.
To transfer data, you need to connect Android directly to your computer. It is not possible to remove the SD from the device and connect it directly to the PC for file transfer. If the drive was used as a portable storage and it contains data, then it is necessary to transfer it to the built-in memory. If you do not do this, then the programs will be removed and they will have to be reinstalled.
When using SD for internal storage, make sure the card is fast. When buying a new drive, look for Class 10 and UHC. If you choose a cheaper and slower SD, then it will slow down the device as a whole. If you have plans to configure the drive as internal storage, then it is better to spend the money on purchasing a fast card. The Android system will test the SD speed during the sync process and warn the user if it is too slow and could negatively affect the gadget's performance.
Do you want to use your MicroSD card as a real memory expansion and install applications on it? To do this, you need to format it as internal memory. This is easy enough on most phones, but unfortunately some manufacturers such as Sony, LG or Samsung do not have this feature by default. But if your smartphone is equipped with Android Marshmallow or newer, then you can use the command line. However, after that, avoid Android updates. We will tell you how to combine memory correctly in this article.
The easy way
If you're lucky, your smartphone will let you do this without connecting it to a PC. This method will most likely be your only hope if you use more new version Android (7.0 Nougat or 8.0 Oreo). Here's how to check:
- Insert SD card into Android phone and wait for it to be recognized
- Open up Settings> Storage
- Tap the name of your SD card.
- Tap the three vertical dots in the upper right corner of the screen.
- Click on "Settings" .
- Please select Format as internal memory.
- Click on "Clear and Format"
- Then Android will offer to transfer data
If your smartphone doesn't allow you to do this, the process becomes more complicated. We'll get to it below.
What to do if your phone won't let you format microSD as internal storage
Some smartphone manufacturers disable the usual Android function to format microSD as internal storage, hiding the ability to do so from your phone. But you can still activate this process using a PC without requiring any root privileges.
The exact steps vary depending on Android version your phone. This method worked well with Android 6.0 Marshmallow and Android 8.0 Oreo, however we ran into difficulties on Android Nougat.
For phones running Android 6.0 Marshmallow
When the MicroSD card is formatted as internal storage, applications can be completely saved on it. This means that if you download an app with a total size of 2 GB, then there should be 2 GB of space on the SD card. If, however, the MicroSD card is formatted only as a backup, there won't be enough memory, according to Reddit.
Just because a menu option is invisible doesn't mean it isn't working. A few days after posting on Reddit, it became known that the command line can also format the MicroSD card as internal memory in the Galaxy S7. We have successfully tested the instructions with Samsung Galaxy S7, Sony Xperia Z5 and LG G4 running Android 6.0 Marshmallow.
All three smartphones work from the factory or after an update from Android 6.0 Marshmallow and have a microSD card slot. In addition, there is no menu option to format the microSD card as internal storage. This feature is only available on HTC One A9 and Motorola on all Moto smartphones.
Why did Samsung, LG and Sony hide this item? I connected each of the three smartphones to my computer and each had one microSD card.
Then I entered in the commands described in my blog. Once you open a command prompt window and connect your smartphone, you can enter the first command:
- adb shell
The Command Prompt is now ready to run system commands on your smartphone. In this case, we want to format the SD card or part of it as internal memory. Even if Sony, Samsung and LG deny us this ability in the graphical user interface, we can still execute this command through the console. First, however, we need the ID of the SD card. You can find it out with the following command:
- sm list-disks
In my case, the disk is called 179.64 ... Perhaps you have it different. Pay attention to the exact identifier. In the next command, we will format and partition the MicroSD card. Your content will be removed. If there are important files on the card, copy them to another drive or computer. If you want to keep the MicroSD card in your smartphone at all times, you can now partition all of your memory. To do this, enter:
- sm partition disk: 179.64 private
The operation takes a few seconds or minutes, depending on the capacity of the memory card. If you only want to use a certain percentage so that other devices can read it, you must exclude it from your personal section. The 50:50 split command looks like this:
- sm partition disk: 179.64 mixed 50
This is the end of Paul O'Brien's leadership, but not the end of the job. If you now want to use re-allocated memory, you must also migrate applications and data. This can be done through the "Storage" section in the Android settings menu. Select your microSD card, then go to the top right side of the menu and press "Move data"... You cannot select this menu item before splitting.
Now all downloaded apps will be completely written to the microSD card. Only system apps and updates use internal memory. This means that you will never get an out of space error message.
Smartphones with Android Oreo
Recent Android updates have changed the rules a bit, but you can still use this method with ADB. Just get started with ADB using the method above, but after typing shell adb you will be prompted to set specific values.
Enter the following lines to unlock the ability to format microSD cards as internal storage on your phone:
G8141: / $ sm set-force-adoptable true
G8141: / $ sm list-disks
- disk: 179.0
G8141: / $ sm partition disk: 179.0 private
G8141: / $ sm set-force-adoptable false
G8141: / $ exit
We tested this method on a Sony Xperia XZ Premium running Android 8.0 Oreo and it worked. In the screenshots below, you can see the 16GB microSD card installed as internal storage:
Problems with system updates and Nougat
Some readers reported difficulties installing system updates in Android 6.0 after using the above methods. Updating to Android 7.0 Nougat is not possible after installing MicroSD as internal storage. Our test devices running Android 7.0 Nougat don't even respond to the console commands shown above.
Due to the lack of documentation on the network, we can only recommend performing a number of operations before updating the system. Back up your photos or music to your computer or cloud and free up as much storage space on your SD card and smartphone as you can.
Delete unnecessary applications and return data to internal memory. Then format the MicroSD card as removable media. Only then can you safely install the Android update.
What's the catch?
MicroSD cards do not work as fast as the built-in memory of a smartphone. So don't waste your money on cheaper ones, but instead buy yourself memory cards with reasonable read bandwidth. and MicroSD from Sandisk were, in our opinion, the best in terms of price / quality ratio. With 74 MB / s write bandwidth, you shouldn't experience lag. These cards are best suited for installation as internal memory
Interestingly, only the LG G4 was able to read the extended memory correctly. Samsung showed an unnaturally large amount of occupied memory, and Sony's memory was even negative. However, we did not have any complications, and even when we were connected to the computer, we were able to access all of our data properly, although we could only see the general and not a specific part of the memory. Difficulties arose only when the system was updated (see above).
Memory expansion: a complete success
We put all the smartphones described above to a single endurance test. We have established Final Fantasy IX on all devices. The game size is 1.8 GB. After installation, it is easy to see which of the two types of memory, internal or SD card, was used. In all cases, after installation on an SD card, 1.8 GB less space. This success cannot be achieved with SD cards formatted as external storage, since a complete data migration is not possible.
Compare the values of internal memory and SD card memory in the screenshot for confirmation.
What happens if you remove the microSD card?
Of course, the question is what happens if the MicroSD card disappears from the system. In fact, this poses a serious problem for your applications. Eventually, they can no longer access their data. Since the sections with your operating system and the factory reset information is still saved in the internal memory, a removed or broken SD card cannot do much harm. When we removed the microSD card, the app icons just disappeared, and when reinstalled, they came back.
If you lose your SD card or break it, your data will be lost. Since they are encrypted as internal storage, you can not hope for data recovery. Use regular backups instead. So feel free to enjoy the cheap memory expansion of your Marshmallow smartphone.
Safely Remove Internal Broken SD Card
To safely remove the SD card from your smartphone, you must undo the above process. Since your storage space on internal storage is probably not enough, you first need to transfer photos and other data to another storage, such as your PC's hard drive.
Then go back to settings "Storage and USB sticks" and press "Move data to internal memory" on the menu. Then format the SD card like external storage. Do both steps (backup and format) so your data cannot be lost and you can use the SD card with other devices.
A flash card is the most functional and popular storage medium in our time. CDs have their own positive sides, but the amount of memory, clarity in application and other factors are on the side of the flash drive.
You can also connect a USB flash drive to an android smartphone, and even the cost today is on the side of the memory card, because cheap options will cost only a couple of times more than DVD-RW.
Only now it is much easier to disable or lose a memory card.
It happens that a person takes this information carrier out of his own smartphone or digital camera, but the computer does not open it. This happens due to virus infection, software glitches, and breakdown of the device itself. In such a situation, it is necessary to restore the micro SD flash drive by changing the partition letter or in other ways.
VARIETIES OF DEVICES OF THIS TYPE
Before restoring a memory card, you should familiarize yourself with the varieties of this small but useful detail. People are not very knowledgeable about this issue, which also brings problems. Today, three types of SD devices are produced: micro, mini, SD.
It would seem, why divide one species into three additional ones. But this is a logical decision, because SD is used in different techniques: camcorders, video recorders, smartphones, mp3 players, etc. Gadgets differ in size and requirements for power and memory capacity of the device. Therefore, there are three subspecies, which are worth familiarizing yourself with in more detail:
- MicroSD. Micro SD memory card is commonly used in smartphones, tablets and media players due to its format and storage capacity.
A small device allows you to increase the memory of the gadget several times
- MiniSD is already slightly larger than micro. They are used on players and phones that are already 5-10 years old.
Today they gave way to the previous version
- SD. This is the largest type that is used in photo and video equipment, in particular, in car recorders.
This option is distinguished by a large amount of memory and a good speed of work.
It is interesting that the first option, if necessary, can be turned into the third with the help of an adapter. A micro card is inserted into this adapter, and then the design is inserted into devices that work with SD.
But this combination will not be able to fully replace the large version, because the speed of work will be too low
IMPORTANT NUANCES IN USING THE MEMORY CARD
- In addition to the amount of memory, the speed is also indicated on the surface of the product (to be precise, the class). So, if a flash drive has this indicator equal to 10, then data can be transferred to the device at a speed of 10 MB per second. It is worth considering what class is required for the normal operation of the gadget.
- A memory card for a phone with an adapter can be used as an SD card. But, as already mentioned, it is not advised to do this due to the mismatch of the class of parts.
- The USB flash drive must be selected for compatibility. When a gadget that opens SDHC is used, it will be able to work with SD 1 or 1.1, but it will not work to read SDXC.
Before buying devices for reading, this characteristic should be taken into account.
Laptops that are 7 or older can be equipped with standard card readers, but they cannot open SDHC. A card reader that connects via USB will help to solve the problem. It costs a couple of hundred rubles. You can also use an otg cable (it will help you connect a card reader for micro sd or a regular USB flash drive even to a smartphone).
SAME NAME OF SECTIONS
Let's return to the problem of unreadability of the device. The flash drive will not appear in the "My Computer" menu if it is given the name D, and the operating system section works with the same name.
fig. 1. It is not difficult to unlock a USB flash drive in such a situation; for this, the "Disk Management" menu opens (a combination of the Win and R keys and a copy of the diskmgmt.msc command)
A menu will appear on the screen, showing the folder of each disc and devices connected via USB. When a memory card appears in this menu, you need to reanimate the flash drive in one of the following ways:
- Put a unique letter in the name, under which there are no sections yet.
fig. 2. This is done by pressing RMB and further selecting the operation to change the letter
- Format the SD card using standard Windows tools or using special utilities. But it is worth considering that all files from the storage medium will disappear.
DRIVER PROBLEM
If you can connect the USB flash drive to the tablet, but not to the computer, then the necessary driver may be missing.
It happens that the employees of the equipment stores forget or do not want to install necessary components and sell computers like that. The equipment must include CDs with drivers, the installation of which will not take much time. If the computer is not new, or the disk with "firewood" is lost, then the almighty Internet will help. In such a situation, restoring a micro sd flash drive is limited only to finding and installing components.
Special utilities are available on the Internet for analyzing the operating system and finding the necessary drivers; they will greatly simplify the task.
CONNECTING WITH OTHER GADGETS
If the flash drive connects to the phone without problems, but you can't see it on the PC, then why not use this smartphone as a conductor and connect it directly to the computer (you can use the otg usb cable)
Most users rarely pull out a memory card to work with files through a computer.
The only question is whether special software is needed for this purpose. In new versions of the operating system, you do not need to install anything additionally, Windows 7 and 8 automatically install drivers for devices. If you wish, you can also use a program from the manufacturer (for example, NokiaPCSuite).
As you can see, restoring the map microsd memory- it's not difficult, sometimes you need to install drivers, change the partition letter or use third-party devices.
