Why want Android to repartition internal memory?

Hello, all. How can I repartition my Android device so that the storage for my phone internal usage (like applications or internal memory) can be increased in lieu of decreasing the User available memory? I have 740MB internal memory and 2GB user available space. How can I repartition to move some phone storage or the user available space to internal memory? I have extra SD card so I don’t require the 2GB in the phone storage. Please help.

As we know, low internal memory on Android phone or tablet will cause new applications cannot be installed and old programs not functional problem. Many Android smartphones have small internal memory, the entry level phones in particular. For example, Lenovo S820 and S920 have only 1GB RAM. The RAM in Galaxy Note and S2 is 2GB. The operating system takes up some internal memory so there is few memory left for applications and personal data. After a period of time, the low space in internal memory notification will appear. As a result, the intent is to partition your internal memory is for better app management as well as Android internal memory increasing.

Before repartitioning internal memory of Android device

Obviously, move applications to external SD card can solve this trouble to some extent. However, the same issue will come back soon in the near future. What’s worse, some software don’t support to installed on SD card. Therefore, you have to adjust the memory. To repartition Android internal memory, your Android device has to meet some requirements and you have to prepare some necessary tools.

▪ The Android device (phone/tablet) has to be rooted before.
▪ An SD card larger than 2GB. If your current SD card has redundant free space, then just partition it. If not, it is necessary to buy another SD card.
▪ A Windows PC with AOMEI Partition Assistant Professional installed.
▪ A memory card reader that you can attach your SD card to.
▪ Download Link2SD from Google Play and install it on the Android device. You can also download a root checker program to check if your phone is rooted or not.

Note: The SD card will be formatted during this process. Please back up important data if necessary. You can copy these files on SD card to any other folder of Windows in File Explorer or you can backup SD card with free backup software.

How to repartition Android internal memory?

1. Attach the SD card of your Android device to the memory card reader and plug the reader into your PC. Make sure it can be detected by your PC. Install and run AOMEI Partition Assistant. 

PS.: You can download the demo version of AOMEI Partition Assistant Professional to have a try!

2. At the main interface of the software, you can see your SD card is marked as a removable disk. Right-click the partition and select “Delete Partition” to remove the partition. Complete the deletion and remember to click “Apply” to execute the operation.

3. Now your SD card shows as unallocated space. Right click the space and select “Create Partition”.

4. In the pop-up window, specify the partition size, drive letter, and file system. Be sure you have some space for the next partition. Select FAT32 if the SD card is larger than 4GB. Select FAT if it is less than 4GB.

5. Click “Apply”, otherwise, you cannot continue.

6. Create another partition with the left unallocated space. Repeat the above steps to create a new partition.

7. Select EXT2 or EXT3 this time in the pop-up window.

8. Then click “Apply” again.

Tips: Windows will recognize only the first partition (primary or logical) so the second partition will not have a drive letter. Also, you cannot view this partition in Windows Explorer.

9. Copy or restore previous files to SD card and insert it back to the Android device. Start the Link2SD to move some applications to the SD card and also you’ll find the internal memory is increased.


How do you repartition internal memory in Android device? To my knowledge, this is a workable method to increase Android internal memory storage. AOMEI Partition Assistant can also format SD ard for 3DS. When you cannot format large capacity removable device to FAT32, you can refer to format 128GB SD card for Android for more information.
