You can lookup if the package name directly in the device details (applications) if it's uninstalled.

Try to enable system app (maybe it's "locked"): enable_system_app com.google.android.marvin.talkback

Try to push and hold both volume keys this should activate TalkBack.

Hello Rafael,

Enable system app doesn't work as it is an ELM agent. The program isn't uninstalled as I checked that as well. And if I remote in and I activate the program I can see it running on the processes.  It is like I need to call a different program to get me to that one. The button will work but I need them to be able to get into the settings. So they can set it up how they want to. (Single tap vs double tap etc, etc)

Try following package:

com.google.android.marvin.talkback.TalkBackService

I found enywhere that i have to block the package you wrote and additional this one to block talkback. Maybe you can use it.

Thank you. I will try that now

Rafael - That didnt work either.

I even tried Launch://com.samsung.android.app.talkback

Did you try to start it via script?

start packagename

If this isn't working maybe the package name is wrong.

Look for "Android Accessibility Suite" in the application list of the device.

Hi Jason,

The bundle-ID and activity name of application(s) to be fixed can differ with different device brand/model/firmware/application versions.  So, instead of posting anything in this forum, checking them out on your devices yourself should always be the most accurate and quickest solution for your own case.

Hello Raymond. Yea I keep scanning thru the bundle id's to see if I missed anything. Just seems odd I cant get it to launch and it says app is not installed. And I cant open up settings as these are credit card payment tabs and i have to keep them extremely locked.

If you can't initiate the program with

  start  com.google.android.marvin.talkback

when your kiosk mode is off, then the app is actually not installed as reported.  In such case, you might need to first find out why the installed status is off or  install alternative app with similar functions from Google Play store.  After solving the problem with kiosk mode off, you can then enable kiosk mode and see it there is any other problem.
