I'm happy with my A7. The screen while not OLED is good and the battery lasts for ages because it's huge. Performance wise it's no slouch either. The 32GB storage is eaten up by the bloat Samsung install to the tune of 20GB, some of which can only be disabled rather than removed. The microSD card cannot be used to install apps to but is accessible to certain apps like All4 to save downloaded films and TV shows to. It's also good for backing up the tablet to. If you have one it's quick charger compatible but comes with a slow charger in the box.
