✏ List of compatible micro SD / SDXC cards for FP4


  • This wiki is just a list by FP4-users.
  • It is there to share experience with MicroSD cards.
  • It is nothing official by Fairphone.
  • Fairphone does not sell any of these cards.

  • This topic is closed to avoid replies, so that the topic can be bumped on the top of the recent topic when edited. Please open a new topic in case of questions or to start a discussion.

Which MicroSD cards do work and which do not? Fairphone does not have the capacity to test MicroSD cards and is not in a position to endorse the use of brands or types of cards. So I hope that the community can help to make a nice list of good MicroSD cards.

Attention!!! → Format SD-cards as external storage

You can format/use SD cards as internal storage (extension of the phone storage) or as external storage.
You will find some explanation on the support page; including pros and cons; and in this forum wiki: “Guide to using SD-cards”
Still, I would strongly advise, to use it as external storage only. If it’s internal storage and breaks, the phone will become unusable. You can’t just change the card for a larger one, should you need more storage or should you wish to play different music, stored on another card. And - finally and most important - the internal storage often leads to trouble on the FP4.
Be aware, though, that also external storage has been reported to cause trouble, see here: SD card problems although formatted as portable storage

This is a wiki, so please edit it with the green pencil above to add your SD card and FP4 experiences. It would be best to keep an alphabetical order; so feel free to add your entry in the middle of an existing list.
