I had 2.2GB free on my Nexus 7's internal storage, then I decided to download a game that took up 1.55GB. Halfway through the download, it tells me that I have have insufficient memory and it stops the download. I then have around 500MB of storage left, and the app is no where in sight and I don't know how to clear up my memory. I decided to factory restore my tablet and afterwords I have 800MB of internal storage (it should have been around 500MB, but I didn't install some apps I had before). Does anyone know how I could get it back to 2.2GB? Thank you in advance.
