First impression (What's new?) Hardware/Design-Lumia 830 come with very smooth and high quality removable casing. Other than that,it's not fingerprint magnet like lumia 920 casing
-Newer phone design (lumia icon) and much lighter compared to Lumia 920
-MicroUSB port move from bottom to top (beside 3.5mm audio jack)
-Soft volume,power and camera button (which i dont really like it ..personally i prefer lumia 920 button)
-Brighter screen and no screen burn issue(overwarm display color temperature at lumia 920)
-Silky sleek touch feeling on the screen and phone
Software-Lumia 830 come with most recent update which is Lumia Demin. While Lumia 920 currently still on Lumia Cyan(my device come together with developer preview)
-Lumia 830 come with much complete and updated camera firmware/algorithm (like live image)
-Lumia 830 pre-bundled more features than lumia 920 ..like motion data,glance screen,brightness profile etc
