I have recently installed a 32 GB SD card on my Android phone. I moved all my apps to it, and they only fill 600 MB of it. I have 152MB available on my Internal storage.
With all this space available, every time I try to install a new app (even if it is really small) I get an error saying that I have to remove unused apps, along with a list of apps suggested for removal. I have already tried to clean the cache, and it didn't help.
