Surprised you haven't seen the most common and easiest bug to reconstruct, the status bar being stuck in landscape mode bug.

Bolding the fonts in iOS 7 doesn't make the typography of iOS 6 return, the fonts are bolder than iOS 6. It actually makes everything worse by clashing bold & thin fonts with the pencil thin dividing lines and outlines. The entire design layout is right off at this point. The neon gradients, bold white fonts and the white or bright backgrounds is even more "busy" and harder to the eyes, b/c the "kerning" is too close together. First year of college Typography class 101, you would tossed out of class presenting that type of "mixed" fonts in your design layouts for your assignments.
Reduced motion is now even more whacked. In iOS 7.0-7.0.2 this function was very useful to get rid of the cheesy Lucky Charms parallax F/X and keep the animations running. Now with 7.0.3-7.0.4 you don't have a choice if you want to keep the animation and turn off parallax F/X. Turning reduced motion doesn't help with the speeds, the delays are more noticeable and you still gotta wait with the "new animation" The fade in & out F/X was introduced 10 years ago to hide how slow certain CPUs were running on the old Palm PDA and Treo 600s.
