I try to download apps like Vine and other apps but, it continuously says insufficient storage and I have an sd card and enough internal storage to download. It makes me angry. Please help, I need don't want but need some apps and it wont let me download. I have a Samsung galaxy ace style and I got it June 13th. Thanks.
I had the same problem on my Huawei Ascend P2, I did a factory reset and it seemed to work, though I highly recommend copying over to your computer every file on your phone before even trying to do so, I don't know the cause myself, the theories I have are:
Virus Damaged internal memory
If it still doesn't work after the factory reset then you need to take it to a specialist (unless you are one) and take it apart and replace the memory.
P.S Don't treat this as a answer as such, I don't have the reputation to comment (which I think they should allow everyone to do instead of risking losing a ton of rep).
P.S.S Have you checked to see if your SD card is being read by your phone?
A simple solution, don't know you have tried or not.
Install any Cache Cleaner apps if possible. Some uncleaned cache may take GBs of data.
If its not possible, delete the files from the cache folders inside the folders in
Android\data\< some_folder > \
