APH shared the following information:

We have identified connection issues for the Mantis Q40 and Chameleon 20 after upgrading to iOS 14.4. We recommend that you turn off automatic updates, and do not upgrade to 14.4. This is a regression introduced by Apple in this release. We alerted them to this issue during 14.4 beta testing, and we hope they will correct it in a possible 14.4.1 release. Stay tuned to your inbox for further updates.

Once upgraded to iOS 14.4, and as soon as users lock their iPad or iPhone with the Mantis or Chameleon connected, the braille display will not automatically reconnect once the device wakes up. You can force it to reconnect by leaving the terminal and reconnecting from there, but then you won't get the braille. The only way to get braille back is to toggle Bluetooth on the iOS device, but the issue will happen again as soon as you lock your device or it goes to sleep.

To stop an iOS device from auto updating, do the following:

  • Open the Settings app
  • Activate the General option
  • Activate the Software Update option
  • Activate the Automatic Updates option
  • Turn off both, "download iOS updates" and "install iOS updates"

If you have already updated to iOS 14.4, please refer to this link for instructions on how to downgrade your iOS device.

If you have any questions or concerns, please contact the APH Customer Experience team at or 800-223-1839. Mantis and Chameleon users can also subscribe to the community user email group for more updates at

Update: With iOS 14.4.1, I personally have not had an issue with pairing my braille display. When typing, VO announcements and braille is quick. The visual text that appears on the iPad screen lags. What is your experience with 14.4.1? Did this update resolve your braille display issues?
