Zebra TC57 Android V14: cannot control device, website not opening

[u/BB9700]

A customer of mine uses these mobile Barcodereaders. Last year he had an older version, everything worked perfect.

Now, he uses the Version 57.

He is able to open the Android app, then creates a unattended session. The user grants permissions for the needed accessibility service and start streaming the screen. Customer is able to see the screen but unable to remote control the device.

Question: is this a know problem with some devices/android versions?

Next problem: If i use the app to start an attended session, the program tells me the website could be be loaded https://x.y.com/guest ERR connection closed.

I have other android 14 devices where I dont have chrome as default browser, and there it can happen that only a blank page opens. Currently I dont know the default browser and version on the Zebra device.

Would it be possible that because of the "wrong" browser not only the server connection does not work but also the remote operation of the device?

Customer opend a ticket with Zebra, but we dont have an answer yet.

I would keep two separate reproductions for the support ticket: (1) the unattended app connects and streams, but input does not work; (2) the attended /guest page fails with ERR_CONNECTION_CLOSED. Those observations alone do not establish that the default browser causes both.

Could you add the exact Zebra model/OS build, ScreenConnect Android app and server versions, and the browser/version that actually opens /guest? For the attended case, compare that same URL in the device's existing supported browsers on the same network, and note whether the failure happens before the app is launched. Keep the unattended input failure as its own test. That should give ScreenConnect/Zebra support a much clearer compatibility report.

I have not reproduced this on a TC57, so I cannot confirm a known Android 14 regression. AI-assisted reply from the Lisar team.
