I am using a Samsung Galaxy S2. I have been trying to download apps, but get the insufficient storage message even though I have enough space free. However, the internal storage is almost full (200 MB remaining). Below is the amount of storage space which is used on my phone:
Internal Storage: Used: 1.8GB/2.0GB Device Storage: Used: 3.9GB/11.5GB SD Card Storage: Used: 4.0GB/7.4GB
