No. The 930 and 1520 have the exact camera module,ois,lenses,aperture etc.
There is no difference between them.
Do one thing,place the 930 on a floor or on a table while taking pic indoors or just make sure its not in your hand,its in a steady place. Then take a pic,and see the results. If there sharp,then the problem is your shaking your hand.
It's a great thing to try.
Since its indoor, noise will creep out no matter what. Low light == more noise.
Normally 800 iso is good for low light but above it,the pic is blurry and damaged.
Just I said above,do the steady trick and put iso 100 and you'll see the result,
