Update unlocks features
An update for Pokédex 3D has now been released worldwide. The update unlocks automatically features previously only available by trading or obtaining through scanning data. The update is downloaded by selecting the "Update" option under menu—it is not received automatically.
The said unlocked features are the pause button, which stops the movement of the Pokémon view in the Pokédex, the SD Card Background feature, which uses pictures from the SD Card in the back of the AR Viewer, the Stopwatch and the musical note, both to be used in the AR Viewer, and the Real Size Button and Scale Slider features, which adjust the size of the Pokémon viewed in the AR Viewer.
