Insert and format a Micro SD card


To extend the memory capacity of your Fairphone 3, you can use a MicroSD card (dimensions: 15mm×11mm) of all available formats: SD / SDHC or SDXC. 

You can use a (Micro) SD card as:

  • Portable storage, so you can store personal data on it. We recommend this option for the FP3
  • External storage, so your phone can store apps on it.


Insert SD card

To insert a Micro SD card in your Fairphone 3, have a look at our tutorial or follow the instructions below.

To insert a Micro SD card in your Fairphone 3:

  1. Open the back of your phone
  2. Take the battery out 
  3. You now see a Micro SD card icon to indicate the MicroSD slot, above the two SIM card slots
  4. Insert your MicroSD card in the MicroSD slot
  5. Insert the battery again
  6. Put the back cover back on
  7. Press the Power button to restart your phone
  8. A pop-up shows with two options:
    1. Use SD card as portable storage. This allows the storage of personal data. 
    2. Use SD card as external storage. This allows apps to be stored on your SD card.


Format SD card

Some SDXC type cards come in a certain format called exFAT. The Fairphone 3 does not support this format, but you can reformat your SD Card to a format called FAT32 (or other formats). There are multiple sources online to help you out with this. Here is one.

We advise to re-format your SD card with your phone:

  1. Go to Settings → Storage 
  2. Select your SD card (do not click the triangle icon: it will eject your SD card)
  3. In the three-dot menu on top right, select Storage settings
  4. Select Format.
