I need to create a second partition on my SD card to use Link2SD to store apps on it, but every time I make a second partition the phone says there is no SD card at all. I've tried it a few times with FAT32, ext4 and none but the phone always says "no SD card". When I delete the second partition it works fine and I can access all the data I had saved to my SD card.

  • I believe the order of the partitions is significant, because Android will only try to mount the first one. Are you putting the ext4 partition second or first? Commented Oct 22, 2012 at 13:04
  • Second, and the FAT32 is set as primary.

Make sure you're making the second partition primary. Both partitions need to be primary, just because it's the second one it still is primary.

  • I did that on a Samsung Galaxy J7 Pro 2017 (SM-J730GM) and it still won't detect the SD card. I partitioned the card on a PC using GParted and made sure to create the second one as primary.
