There are connection issues for the Mantis and Chameleon after upgrading to iOS 14.4. We recommend that you turn off automatic updates and do not upgrade to 14.4 until a resolution has been found. 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. We’ll keep you posted on anything that we learn. 


What’s Happening

The basic issue is that once you upgrade to 14.4, as soon as you lock your iPad or iPhone with the Mantis or Chameleon connected, the braille display will not automatically reconnect once you wake the device back up. You can force it to reconnect by leaving the terminal and reconnecting from there but then you won’t get 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. 

 Another way that this issue can manifest is if you don’t lose your connection but use the braille display to wake up the iOS device, you can successfully wake it up and regain your connection but you will stop receiving braille. Regardless of how the issue appears, it is best to avoid it altogether by not upgrading to 14.4. 


What You Can Do

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’ve already updated, please refer to this link for instructions on how to downgrade your iOS device: How to Downgrade iOS. Note that downgrading is a complicated and time-consuming process. You’ll want to back up your data before downgrading as the process will wipe everything. 

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
