Android Partition Manager: How to Partition SD Card for Android
Computer, SD card, and mobile phones are places to store files, but the capacity is not enough as you do more of these devices. Then you will plan to partition. So how to Partition SD card for Android?
A partition is simply a logical division of mass storage or memory into isolated subdivisions. This is normally done to help reduce the burden of the internal storage on the device. In other words, people usually create partitions on the SD Card in order to save more space on the internal storage. Partitioning can help to enhance your disk efficiency. Moreover, it is said that a partition can speed up the Android operating system by a huge margin.

Unlock your bootloader
You now need to unlock your bootloader. For the sake of those who are not familiar with Android bootloader verbiage, let's get some basics out of the way first.
A bootloader is essentially a system designed to instruct the operating system kernel to boot normally. It is usually locked on an Android device because the manufacturer wants to limit you to their Android Operating System version.
With a locked bootloader on your device, it's nearly not possible to flash a custom ROM without unlocking it. Applying force may likely break your device completely beyond repair.
Note: This guide is meant for Android devices with Stock Android OS only such as Google Nexus. Google's Stock Operating System is the kernel of Android without user interface UI alteration.
Step 1: Download and install the Android SDK on your system.
Step 2: Once you have downloaded and installed the SDK, shut down your device and restart it in bootloader mode. Here is how you can do it:
- Nexus One: Press and hold the trackball and power button simultaneously
- Nexus S: Press and hold volume up and power button
- Galaxy Nexus: Press and hold the power button, volume down and volume down at the same time
- Nexus 4: Volume down and power button
- Nexus7: Volume and power simultaneously
- Nexus 10: Volume down, volume up and power button
Step 3: Connect your Android phone or tablet to your PC via a USB and remain patient till all drivers are successfully installed. This usually occurs automatically.
Step 4: Once all the drivers are installed, go to terminal interface on your PC/command prompt and type following command fast-boot oem unlock.
Step 5: Now press enter and your device will show a screen that will alert you about bootloader unlocking. Carefully go through the instructions on the screen and confirm by pressing the volume up button and power button one after the other.
Congratulations! Now you've successfully unlocked the bootloader on your Android device.
For Android devices with non-stock Android, you may want to download the unlocking tool from the manufacturer's website. For instance, the HTC official site has a section where you can download an SDK. You only need to know the model of your smartphone.
However, Samsung website does not offer this service, but you can find unlocking tools for Samsung devices. There are also tools you can use to unlock your Sony mobile bootloader.
Again, be sure to install the version intended specifically for your phone model. For LG handset users, unfortunately, there isn't any official section to offer this service. But you can try researching online.
Root your Android
Rooting varies for each device running the Android operating system. It should be noted that this is a very risky process that may destroy or spoil your phone and revoke your warranty. Most phone manufacturing companies take no responsibility if the problem is caused by rooting. Hence, root your smartphone at your own peril.
See how to safely root Android in simple steps. These are the easy-to-follow steps on how to root Android. This way supports most Android models.
But in case that this way does not work on your model, you can try the following rooting method (though it is somewhat more intricate).
Step 1. You will need to download the latest version of SuperOneClick and save it to your laptop or desktop.
Step 2. Connect your Android to your computer.
Note: Never mount the SD card on your computer; the safest method to just have it plugged in. Again, go to the Settings and enable USB debugging.
Step 3. Finally, hit the “Root” button on SuperOneClick. Nevertheless, if your device has a NAND lock, it may fail to unlock. In such cases, click Shell Root button rather than Root button. See the image below.
Step 4. Once you have clicked the Root Button, it may take a while before the process is finished. Once finished, be sure to reboot your device.
In this tutorial, we will take you step by step through the process of partitioning the SD card for your Android device, so that you can run programs from it.
This is an example of a 16 GB Micro SD card, but you can choose your preferred size as long as it is over 8 GB. Follow all the instructions carefully to avoid any potential problems. Again, this post will not be liable for any inadvertent damages in your phone, Micro SD Card or hardware.
Now have a look at how to do it:
Step 1. First and foremost, connect your SD Card to your PC using an adapter and then open MiniTool Partition Wizard Manager. As said earlier, you can download it online.
Step 2. The SD Card should be showed with five partitions. The only one you need to concentrate on is partition 4 which should be named as FAT32. You will have to resize this partition to your preferred size. This will be the main drive where the Android and the rest of the files will be kept.
Step 3. Select Create as Primary. Determine the size for this partition by factoring out about 32MB for your swap partition and 512MBs for your applications from the maximum size. The 512 partition should be set as an ext4 or ext3. The 32MB partition can be labeled as swap. However, a particular ROM may need a different number apart from 32; thus, always follow whatever is recommended by your ROM developer.
Now that you have all the space of the Micro SD card reserved for one of these 3 partitions, click the “Apply” button and wait for it to finish the process. However, be sure you've set the appropriate file system—FAT32 and Ext2 and both of them formed as PRIMARY.
Wait for it to finish the process.
Step 4. Insert back your SD card to your cell phone and reboot it. Now that you've switched on your phone, go to Google Play Store and download Link2SD. After you have installed the app, you will be prompted to select between ext2, ext3, ext4 or FAT32.In order to work properly, you must choose ext2. The ext2 partition is where your applications will be installed.
Step 5. Once the manuscript has been created, restart your device right way. Open link2SD and if the message does not indicate, it means you are successful. Now go to Link2SD > Settings > Check the auto-link. This is done to automatically move apps after installation to the ext4 partition.
To check your memory, click “Storage Info”. This should show you the existing state of your ext2 partition, FAT3 and internal memory in overall.
