my son was playing with my phone I dont know what he did but now everything is in negative

Go to settings/accesibility(or ease of access i dont remember)/sight->uncheck negative colors (walkthrough on Note 4 , i think its the same)

How best I’m i going to get a good results back

Go to settings. Then go to accessibility. And turn off high contrast mode.

Newer iOSs Settings –> General –> Accessibility –> Display Accommodations –> Invert Colors. Older iOSs Settings –> General –> Accessibility –> Invert Colors
