I recently bought a 16GB and i tried to download an app and it said "there is insufficient space on this device" It says i have 16 GB remaining but is not letting me download anything.
Your phone probably, by default, does not download and install apps to your SD card. It uses your internal storage for that. You'll need to root your phone/use third-party apps in order to change that.
