Quite often, when panning through text using a braille display, the panning command or buttons will not respond, or will respond twice when twice skipping past content that should be displayed.



This started in iOS 15.3, as reported by several AppleVis users. I have now experienced this with a few displays randomly.

Steps to reproduce

Load an email or website and start reading.... It won't take long

Bug First Encountered

iOS/iPadOS 15.3

Device(s) bug has been encountered on


How often the bug occurs



It seems that the System braille tables are more reliable, but the issue still occurs. When panning freezes, press space with 2-3 or space with 5-6 and it will unstick, though sometimes if you have Word Wrap enabled, it will turn off.

My wife is a deaf-blind person. As a result of this error he is unable to use sms, phone. 15.4 beta 5 still contains this bug. Fix it at last! Why aren't you downgrading to an earlier version THIS IS VILLAIN, wicked and sadistic what you are doing! You cut some people off from contact with the world. You are spoiling what you have done !!! Your service in Poland does not pay attention to it, they are not even able to contact you, and you do not even realize it!

I would recommend contacting Apple with this exact feedback. Sadly, AppleVis itself can only publish our findings. What type of braille display is your wife using?

I will connect a Focus display and see if I'm having the issues there. It seems fixed for me on a Brailliant.
