My samsung galaxy s went to negative color on its own. It looks like an old school film negative. The battery light is now horizontal in the batter picture...what the

I up dated some apps, that I have never had issues with through the google market place, set my phone down and Came back to make a call and my phone wigged out. it is now in negative color, like an old school film tape after its been developed. I cannot see anything in clear color. however when I hit set up the original color comes through for a second. The battery light is now horizontal instead of vertical. I reset my phone, but took the sd card because I didn't want to loose anything on it. What do i do? Is it repairable?
