Hello this may be a dumb question. I upgraded awhile back to the S3 but one issue I've have, due to my vision its getting harder to see everything on the black background with white lettering. I was recently at at&t and seen the Galaxy S4 and how the OS has the white background with black text making it more easy to see. I love the white color scheme as far a contact list, dial pad . Is there anything I can do to get this on my S3. Im not due for an upgrade yet. I know on some older android phones gave you the option to switch from black to white. Thanks for any info!
