The problem of lack of memory is one of the fundamental problems for both PCs and mobile devices. With a small amount of free memory, the system usually starts to slow down, freeze, work unstably and unreliably. This is especially true for Android devices, many of which initially have a rather small amount of main memory (the so-called "Internal Storage"). In such a situation, some users may have the idea to try using external SD card as the main memory on their Android device. In this article, I will tell you how to make an SD card the main memory on Android gadgets, and what methods will help us with this.
We analyze how to make an SD card the main memory on AndroidWhat you need to install an SD card as main memory on Android
To accomplish this task, you will need a high-speed SD card (preferably class 10 or faster). Cards 6, and especially 4 and 2 classes are not suitable for such purposes, your system will significantly slow down its work due to their use, which is unlikely to please any of the users.
It is also important to understand that the validity period of such an SD card, due to the active load on it, will be significantly less than if the card was loaded in standard mode.
Method number 1. Change the contents of the Vold.fstab file
The first of the described methods involves changing the contents of the file system settings Vol.fstab. After making these changes, the Android OS will consider your SD card as the internal memory of the device, while keeping in mind that a number of previously installed applications may stop working.
It is important to know that this method only works on rooted devices running Android OS below (!) than version 4.4.2. In Android OS versions 4.4.2 and above, most likely you simply will not find the specified file.
Also note that an implementation error this method(in particular, adding extra characters to the necessary lines) can most sadly affect the performance of your device. 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:
For example, these lines could be:
- dev_mount sdcard/storage/sdcard0 [email protected]
- dev_mount sdcard2/storage/sdcard1 auto/xxxxxx
To make the necessary changes, we need to change the path in the specified lines, that is, in other words, instead of 0, put one in the first line, and in the second, put 0 instead of 1.
After the changes, these lines will look like:
- dev_mount sdcard/storage/sdcard1 [email protected]
- dev_mount sdcard2/storage/sdcard0 auto/xxxxx
Save your changes and then reboot your gadget.
Another option on how to make a memory card the main one on android:
Method number 2. We use the settings of Android OS 6.0 and higher
In addition to the first method, in which I looked at how to switch the phone's memory to a memory card, there is another method that works only on Android 6.0 (Marshmallow) or higher OS settings 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 map will be formatted by the system.
Do the following:
Conclusion
In this article, I have considered options for how to make an SD card the main memory on Android. It is important to consider that these methods do not always work - the first one requires root rights and the Android OS is lower than 4.4. whose implementation the last way 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% result in this case.

A common question, how to enable a memory card on a phone, is of interest to many owners of mobile devices on which free space for storage useful information turns out to be very few.
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 placed on the gadget panel, on the side.
- Then the selected map is loaded here, 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.
Typically to detect telephone memory card, nothing more needs to be done. 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
Often, reading information from a working memory card becomes a real problem. What to do 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 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 must first 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 starts 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 a memory card that will be the largest 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 volume permanent memory and RAM, then he probably often uninstalls programs to free up space. But there is a way to increase the amount of memory by using an SD card.

Default games and android apps are installed on the built-in storage of the smartphone, which may be too small. If there is an SD, then you can make sure that some programs are installed there by default, thereby freeing up space for more information. At certain conditions You can transfer almost any installed program to a removable USB flash drive.
How to install an app on an android sd card? There are several different ways carrying out this operation. Selecting the correct method depends on the version operating system and data to be moved. AT android settings 6.0 Marshmallow 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 move the application to the memory card manually, but only if the developer allows it. Alternative way program transfer - using the Link2SD application.
It should be noted that programs launched from the card are likely to run slower than those that are in the built-in memory.
That is why you can only transfer applications to an external flash drive in case of emergency. 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 that 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 affecting functionality.

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

Now about how to set up the SD card. It is necessary to create backup data and save it to your computer before using the flash drive as internal storage. The onboarding process will delete all data. You can return data to SD after the drive is accepted as built-in storage.
To transfer data, you need to connect Android directly to the computer. It is not possible to remove the SD from the device and connect it directly to a PC to transfer files. If the drive was used as portable storage and it contains data, then you need to transfer them to the built-in memory. If you do not do this, the programs will be deleted and they will have to be installed again.
When using SD as internal storage, you need to make sure that 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 there are plans to set up the drive as internal storage, then it is better to spend money on getting 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 performance of the gadget.
The internal memory on smartphones is not infinite, and photos, videos, documents, and applications take up quite a lot of space. That is why most devices have an SD card slot - this allows you to significantly expand memory reserves.
And yet, users are faced with such a problem: an external media is installed in the phone, but all applications are automatically downloaded to the internal memory. Because of this, a notification constantly appears that there is not enough space. On Android, this problem can be solved in several ways.
How to download games and applications to an SD memory card
There are several ways to apply external card to download apps and games. So, you can set the SD card as the default memory, move applications using default settings or memory pooling.
Setting External SD Drive as Default
You can set the SD card as the default memory, and then the smartphone will determine it as a priority for data storage.
For this:
Some applications will still be saved during internal memory, this is determined by their settings.
Using Settings to Move Apps
Unfortunately, in the settings there is no option to choose automatic installation applications to external media. But you can manually move some of them (not all applications support such a transfer).
For this:
There is another option: you can transfer applications not individually, but all together. For this:
Combining internal and external memory
This method is available for smartphones that have android version from 6.0 and up.
