Why do i get "Insufficient storage" when the so called "usb storage" is almost empty? Samsung Galaxy S2 is the model
I get no free space error msg when i try to install application from Google Play.
So i navigate to Settings->Storage and i see 3 sections:


Device memory - 200MB Free
USB Storage - 11.1GB FREE
SD Card - 413MB FREE 


Why cant the phone install it on the usb storage?
External application cant install on usb memory as it is a external memory of your phone so you have to empty your phone memory stuff which may be songs, pics or the items which can store on external memory so that your application will install. or simply unistall the unwanted applications. It will help you to free internal memory
