- 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.

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.
General Advice when looking for a FP4 micro SD-card
Here is the offical Fairphone support page for installing a Micro SD card.
It is advised to re-format your SD card directly from your phone.
