Question Galaxy A3 2017 weird colors

[PlsHelpmeSon]

Hi my Samsung Galaxy A3 2017 randomly has weird colors now. Some are very bad contrast and some you can't even see. And if I try uploading an image with the browser it crashes and shows the message "Android system has stopped". Everything looks very messy in settings the text below a setting is pink. Checkboxes have a doodle like gray look and everything is black. If someone could help me with this it would be greatly appreaciated. Also it would be nice if I could avoid a complete factory reset.
