Hi,
The wiki (✏ List of compatible micro SD / SDXC cards for FP4) states “Fairphone sais that the capacity of MicroSD cards should not exceed 400 GB” and links to the official FP support page (https://support.fairphone.com/hc/en-us/articles/4405858570257) which says “The maximum storage capacity for cards that can be used with the Fairphone 4 is 2TB”.
So… 400GB or 2TB ?
