[Android Central Question]

Tab has 8GB internal 32GB card. When I try to download app, says not enough storage. With all that space available, why can't I install app?

Welcome to Android Central! Which tablet do you have? The SD card most likely isn't available for app installation -- this would only be if the tablet supports Adoptable Storage, and you formatted the card as Internal Storage, not as Portable Storage.

How much of the 8 GB of total Internal Storage is free?
