TeamViewer Universal Add-On

Doesn't work in new Samsung devices with One UI 7.0 running on Android 15. TV customer service claimed that device needs to have knox installed in it without knowing that it is a built in app in ALL Samsung devices. This company's service has been great in the past but now apparently falling apart as Android is progressing and eventually will become useless for future devices if effort not given to update it with the evolution of the OS it is running on.

The add on works fine for a few times but after no use for a day or two, it stops working. Please fix this. EDIT- I found a fix for this. Every time the add on stops working, I just need to reinstall it. But this is a temporary fix as I'm not always present near the device I want to access and so it's not possible to reinstall the add on every time I want to access it. Also, only the swipe gets disabled. I can still double tap to wake my device (I'm using teamviewer host for unattended access).

Well, it DOES work but only after setting a vital permission which is not immediately obvious. After installing this add-on you must go to the Accessibility menu of your Android device and enable the Universal add-on Accessibility Service. A pop-up during installation does tell you to do that but tapping the blue ENABLE option on that pop-up appears to do nothing. Now you should be able to remote control the device, but the hand that appeared in "read only" mode now vanishes so the person looking at the device can no longer see your actions except through display changes. PS: My test device was a Xiaomi A2 Lite.
