iPhone mail displays messages at half-width
Using the standard iPhone Mail program, most of my email messages are being rendered at half the width of the screen rather than filling the entire width. It does not appear to matter where the messages are coming from or what they contain.
My ipad does not have this issue. As you can see in the screenshot below, it looks like the mail program is getting confused about the width of the screen and wrapping text at what looks like exactly 50% width. The message header and title are OK.
Here is a screenshot:
