    I tried formatting it to fat32 and other formats on a PC, I tried formatting it with a custom recovery but it keeps saying that there's no space left on the micro SD card. Using it as external storage works fine.

    Are you sure the card isn't a counterfeit? This is quite common..

    Yes, it's a SandDisk Ultra 64gb bought from a reputable store. And everything else works fine, it's just that it gives an error when formatting it as internal storage

    Double check with the SD Insight App, which tells you if it is real.

    Yes, the app says it's a 64gb sd card. I also tried using a 2gb sd card as intrenal storage, but it gives the same error.

    Adoptable storage CAN NOT be read by a computer. FAT32 CAN NOT be read by a phone expecting adoptable storage. You have your choice of one OR the other, not "and". You've probably lost whatever was on the card by now. Your best bet is to format the card as adoptable storage and leave it that way - if you must. (Remember, SD goes bad a lot faster than eMMC [the internal storage in the phone], and to expand the card, you have to move everything on the current card to the phone, remove the card, install the larger card, then format it to internal and let the phone put things back on it. To me it's not worth it. External 2 Internal SD (Root) is a better solution if internal and external sizes are different enough. As Samsung says, the technology is made for 3rd world markets, where the common phone has 4-8GB internal storage, and SD card prices have dropped through the floor.)

    Thanks for the big answer, but I know all that. The problem isn't that Windows can't read it and says it's corrupted, but the problem is that Android does. I tried different formats besides FAT32, but which one would you recommend? And I'm definitely going to try External 2 Internal.

    Windows CAN'T read the card. Nothing can read it but the phone that encrypted it. As far as any other device is concerned, it IS corrupted.

    A 64GB card has to be formatted exFAT.

    I found that the problem lies in the custom rom I use (BlissPop for 6.0.1), it works fine on the stock firmware. Thanks for the help.
