By Jessica Brown, 28 August, 2015 Forum Braille on Apple Products Hi. I heard iOS 8.3 was supposed to fix the braille display lag. I don't know about 8.3 because I whent from 8.2 to 8.4. However, the lag is very bad on iOS 8.4. Anyone else on iOS 8.4 and still having problems with lag on there braille displays?
