How To Use Sd Memory As Internal Memory Of A Smartphone

Do you want to use the SD memory card as the default location to install applications and increase the memory capacity of your smartphone?

Well, then you have to convert it to internal memory. 

This memory change is very simple on most smartphones, but unfortunately, it is not possible to do this by default in some smartphone companies. 

If your smartphone is running Android 6.0, a simple code can solve this problem. The following article will help you step by step to use the external memory of your smartphone as internal memory without the need to update the operating system.


The first solution: easy and fast

If you are lucky, your smartphone will allow memory conversion without the need for a computer connection. It should be noted that if you are using newer versions of Android (version 7 Nougat or version 8 Oreo), this method is probably suitable for your situation:

Note: Before performing the following steps, be sure to move your important information to a safe place to prevent the accidental deletion of information.
  1. Insert the external SD memory into your smartphone and wait for it to be detected.
  2. Go to Settings and click on Storage settings.
  3. Click on the SD memory name.
  4. Touch the three small dots in the upper right corner of the screen.
  5. Then select the Storage Settings option.
  6. Select the Format as an internal memory option.
  7. Finally, click on the Erase & Format option.

In this way, the Android operating system will allow you to transfer information to external memory.

What can I do if my smartphone does not allow me to use SD memory as internal storage?

Some phone manufacturers, such as Sony, LG, and Samsung, disable these default Android settings but do not worry, you can still reactivate them by connecting your smartphone to a computer. This method does not require rooting the device or any special technique.

The steps of this method are different in different versions of Android and it works best in Android 6 and Android 8, but in Android 7 the story is a little different and may cause problems.

Use SD memory as internal memory in Android 6 Marshmallow

When SD memory is selected as internal storage, various applications can be easily stored in it. This means that if you download a 2 GB application from the Internet, it will occupy the same amount of capacity as SD memory.

Recently, a new command line was discovered by users that allows you to change the SD memory to internal memory. This method has been well tested on Samsung Galaxy S7Sony Xperia Z5, and LG G4 smartphones.

All of these smartphones run Android 6 and support SD memory by default. In addition, the memory change settings are disabled by default in all of them. It is surprising why companies like Samsung, LG, and Sony ignore the importance of these settings.


To get started, insert the SD card into your smartphone and connect it to your computer with a USB cable.

Now you have to enter commands using the ADB tool. When the command line window is open and your smartphone is fully connected to the computer, enter the following command:

Adb shell

Now the command line is ready to receive your commands. In this case, in particular, we want to use SD memory or part of it as internal storage. Even if Sony, Samsung, and LG prevent us from accessing these settings, it can still be done by sending commands.

First, we need the SD memory ID.

Then enter the following command:

Sm list-disks
In the next command, we have to format the SD memory and then partition it. Note that after formatting, all data in the SD memory will be erased. So if there is important information in memory, move it to another location. To partition the SD memory, enter the following command: The memory ID code is displayed. In our test, the number was 179.64, but it may be different for you. Write down the ID number on a piece of paper.

sm partition disk: * private
The operation of the memory card capacity may take from a few seconds to a few minutes. Enter ID number instead of *.

If you want to define a certain percentage for your smartphone, you can specify it with the following command:

sm partition disk: * mixed 50
Well, you have almost completed the main part of the trick. Now if you want to use SD memory as the internal memory of the smartphone, you have to move the data and applications to the new memory. Go to the smartphone settings and select the MicroSD option from the Storage section.

Then from the top menu, right-click on the Move data option. This is the same option that was disabled before partitioning.


From now on, all downloaded applications will be fully stored on the SD memory card, and will only use the device’s internal memory for Android system applications and updates. This means you no longer have to worry about memory shortages in your smartphone.

Problems updating the system and the Android operating system 7

Some users reported problems updating the operating system from Android 6 to version 7 after changing the internal memory of their smartphone. Manual partitioning of SD memory does not seem to be compatible with Android 7, so avoid updating your Android to this version as much as possible, but if you encounter this problem, we suggest restoring the internal memory to its original state.

Transfer your photos and important information to your computer and then free up some of your device memory.

Remove unnecessary applications and transfer application data to the internal storage from the settings section. Then format the SD memory card. With this, you can update the Android operating system as before.


important points

MicroSD memory cards are not as fast as the internal memory of a smartphone. So do not waste your money to buy a cheap memory card and instead get a strong memory with high-speed efficiency. In this case, Sandisk Extreme Pros and Extreme Plus can be your best choices as they give you a speed of 74 MB / s. Therefore, after changing the memory, you will not face any delay in the performance of your smartphone.

It is interesting to know that in the tests performed, only the LG G4 smartphone was able to calculate the amount of new SD memory correctly. On the other hand, after receiving the new memory, Samsung showed a strange capacity on the screen, and Sony also calculated the memory capacity negatively (!).

However, there were no problems with these three smartphone models. Even if connected to a computer, all information was easily accessible. The only problem users reported was updating the operating system to Android 7.  

Successful change of internal memory

We tested the trick of changing the internal memory on different brands of smartphones and, for example, installed the heavy game Final Fantasy IX on all devices. The size of this game is about 1.8 GB and after installation, it was easily found that all the information was successfully stored in SD memory.

The image below shows the information and memory status after the steps of changing the internal memory to an SD card.



What happens if we remove the SD card?

Removing an SD card from the system can cause serious problems for applications. These applications lose access to information stored in the SD memory, and since the Android operating system and factory data are still in the internal memory of the smartphone, removing or damaging the SD card will not harm the operating system. When you remove SD memory from the device, the application icons disappear immediately, and if you reconnect the memory, they quickly return to the previous state.

If you lose your SD card or it may damage for some reason, your data will also be lost. The data could not be restored because you saved this type of memory as internal storage on your phone. To prevent this from happening, I suggest backing up your important data from time to time.

How to safely remove SD memory from your smartphone?

Repeat the above steps to safely remove the SD card.

Then go to Memory & USB from the settings and touch the Move data option. After transferring the data, completely format the SD memory.
