Today during quick shot mode  ( Asteroid and rocket mode ) i got message twice  that object is lost , why this happened ?If my friend standing beside me and we are 2 objects  (2 green small dots) could this affect the tracking ?

This happens from time to time I would say. It's annoying but you have to start over. Happens when i'm alone as well and can't say that two objects makes any difference.

happy flying

Keep in mind tracking is not 100% reliable as the subject keep changing shape when moving. It can also be blocked by other objects around. If the object becomes too small or can’t be see by the camera the tracking is lost. If the shape or colour change too much the tracking also lost.

So  which is  better to let the camera grack the green dots or to draw a green box around the object ..?and what are the differences in either cases?

The difference is that you can choose your own object by drawing the box yourself..

draw the box around one. it will work better if two of you are standing close. But always draw a box around the "subject". the green dots really only represent subjects it recognizes. the box will lock the quad on one better.
