im using my 16gb memory card as to store all my apps on etc.. as my internal memory is too full so i chamged my sd card to default storage, but now as i have been using it it says storage space is getting low... but when i check it i therefore have 14gb left in total space i can use but it wont let me ... that's heaps of space I can use, I've tried moving apparently from sd to phone but internal is too full so I can't... I don't see how I need to do that anyway as I've only used up 2gb on sd and yet have 14gb I can use but why is it saying low on storage space on my sd? And how can I go by using the other 14gb ?

  • I assume your device (name?) is rooted? How did you make your SDCard the "default storage"? I know it's possible on some devices to switch internal/external SDCard addressing, but I've never heard someone switching device-internal storage to SD.

This may be expected, depending on what phone you are using. The original standard of SD card readers had a 2GB limit on them. These readers could read cards that had more space, but only had enough memory registers to read the first 2GB of them. Sometimes a firmware update can increase this from 2GB to 4GB, but it's extremely rare.

From the wikipedia article on the SD standard:

SDSC (SD): 1 MB to 2 GB,
   some 4 GB available.
SDHC: >2 GBs to 32 GB
SDXC: >32 GB to 2 TB,
   some 32 GB available.
  • So there is no way I can change it? Commented Jun 4, 2014 at 2:04
  • You mean, there are really Android devices out there being bound to some standard that old? SDHC was released 2006, according to the linked Wikipedia page. The first Android devices came 2008. I doubt even the very first ones came without SDHC.

  • This is why I said "may be expected". Depends on the device and whatever settings are anywhere else. There isn't any information on what device is being used, but it's the only thing I can think of that would limit a card to 2GB. It may even be a software issue that is locking the phone to the old SD standard instead of SDHC, which a firmware/software update can fix.
