This is an extremely minor but extremely frustrating issue with my Galaxy S3.
Basically the email client out the box (synced to my Exchange Active sync account) has a black background and white text...so far no problem.
However as people have been sending emails to me the phone seems to (arbitrarily is seems) to render either a white background or black background.
I then thought no problem I will switch the font colour to white...which works great when the email is rendered with black but renders the email text invisible when a white background email comes in.......has anyone had a similar issue??
