iOS 7's switch to the Helvetica Neue Ultra Light typeface was one of the bigger design points for the new OS. But it came with a catch: It looked, in places, pretty bad on non-retina screens. The fix was simple enough. Just change it back to regular weight.

The newer version for both GIFs is the frame with the lighter blue background, instead of grey. The differences can be seen all over the OS, in Messages, Weather, and other first party Apple apps.

Still, this throws the weight of the entire OS off from where it had been, even if just slightly. [Twitter]
