Looked at the sun for 2 seconds taking a pic with my cel. but closed my eyes right away. can i get blind now i'm really afraid. how soon symptoms show?

Do not worry: But be careful. Sun induced retinal burning is usually instantaneous, and more often when image is magnified such as looking at sun through binoculars or telescope. Especial risk with newtonian reflector device. If you must visualize the sun, utilize special filter, or reverse imaging, never directly unfiltered.

Unlikely: What you need is reassurance about what happened to you. You momentarily had the sun imaged on your eye but your pupillary response is fractions of a second and your avoidance of bright light is also active. So you probably never had enough sunlight at one spot on your retina to do any damage. You can check by looking at a grid graph paper with each eye and see if the grid is intact.
