If you had the original transform, which was junk, this is not the same phone. Fast and responsive. Enough RAM to do what it needs to. The only thing holding back a 5 star rating is the fact the hotspot does not work correctly. HTTP works fine, but HTTPS fails miserably. Sprint tech support did not have a clue how to diagnose or fix it. Also, I preferred the old touch navigation buttons instead of the Ultra's physical buttons.
