I have a brand new 32GB SD card barely used, my phone even shows that it has 31.23GB of storage available, however when attempting to download an app it says I do not have enough memory. I have double checked that the SD card is the default storage on my device, but to no avail. Please help, I just got the memory card and can't even use it.
Google Play downloads app data to internal storage first then installs the app to external, hence the low storage message. There is no way to change this without rooting and using a symbolic link.
You can't have apps on an external SD card without you phone being rooted.
