Hi all, I'm using a iPhone 6 Plus running IOS 9.1. I turned on bold text a few days ago (aging eyes) and have noticed a lag that started a few days ago as well. Turning off the bold text, the lag has seemed to disappear. Has anyone else noticed this? I'm wondering if there is a lot of extra work for the OS to do in rendering the bold text, but that's just a guess. I haven't had any problems with lag since I upgraded from 8.4.1 to 9.0.1 With the exception of turning on the bold text under 9.1, my phone has been pretty zippy overall.
