How To Upgrade the Disk Space on an Android Mobile


Since the beginning, adding memory and larger hard disks has always been the easiest way to upgrade and extend the life of your PC. Well did you know the same is true for your Android Mobile device?  Although adding more “memory” is a bit tough, adding additional disk space is as simple as swapping out the default memory card.  I recently upgraded my mobile from 8GB to 32GB for just a few bucks.

Although for some, this groovyPost might be fairly basic, being that I just upgrade my memory card I thought this would be a great begginerGeek post to review the simple steps!

Upgrade Disk Space on Android

Step 1

First, we need to transfer all the photos and images from our old memory card to our new one.  So, eject your memory stick from your mobile and connect it into a memory card reader connected to your PC.  Fire up Windows Explorer and enable it to show hidden/system files.

Hit Alt to show the pull-down menus, then select Folder options, just like I did below.

Now, in the window that pops up, select the View tab, then Show hidden files, folders and drives and then hit OK.

Step 2

Go to the root of your old Android phone card and select all of the files on it, then copy them to a folder on your computer (I suggest creating a special folder for this, something called “Backup”, so that you can easily find it).

Step 3

After everything has been copied, remove the old card from the card reader and insert the new card into the card reader.

Step 4

Copy all of the files in the Backup folder you created on your computer to the root of the new card, just like I did below.

Insert the new card into your Android smartphone’s slot. Everything should be just like before, except for the fact that you’ll have much more space to use, just like a hard drive upgrade.

      The problem could be the reader, then. Does the card work in the phone or in a different reader?

    I’d just like to post some big ups for the advice. Upgraded from 2GB to 16GB memory card and everything is working perfect.

    There are a lot of people saying you need to do this in rescue mode. I’m no tech-head so things like that scare me!

    You’re advice is simple and it works!

    Who needs rescue mode.

    Bogdan to the Rescue!!

    Thank you. I knew there was an easier way.

    Great article, thanks for this. However, in my case, when I try to copy from the computer back onto the new memory card, it stalls. I get a pop up telling me to “remove the write protection or use another disk.” How can that be? How do i do that? Do you have any suggestions?

      Hey, Yeah I get the same thing. Fine copying from my old memory card, to my computer, but when I tried to put it onto the new one it wont let anything copy, askes for the copyright protection to be removed.
      … well except for one empty folder that I now can’t remove. (O_O) Says its corrupt.

    Or could I just do the following steps:

    1. Switch off my android phone.
    2. Connect my android phone via a usb cord
    3. transfer all data from memory card to computer (using win explorer)
    4. Replace memory card in phone
    5. Click on Settings – Storage – Erase all data
    5. transfer data from computer to memory card (using win explorer)
    6. Switch on android phone and start using as before
