@ladoga on 1.0.2 if you quit right away after snapping photos are not being saved. Here's a 1.0.3 with that problem resolved.

On the other hand, your problem might be unrelated, see pages 6-7 of this thread.

1.0.3 also has image stabilization please test and comment.

Burst mode takes 8 pictures and keeps the sharpest (just like FCamera). Accelerometer mode waits for your hand to stabilize before snapping. If you take too long to stabilize the threshold increases so that it eventually takes a picture.

The values might need some tweaking but it seems that it works as expected though I haven't tested it in real life.
