Why doesnt my zte quartz download onto my SD card with games?
It is not possible to move apps to your sd card on the Quartz. One of it's small downfalls you have to overlook.
Hmm.. When you go to Settings > Apps > Tap a game you downloaded, can you see "Move to SD card" or "Move to Internal storage"?
If not, try using Link2SD (link).
Let us know how it goes.
