"In line with the fears over scams, Kasikorn's app, like some of the other banking apps, had required --for the last few weeks-- the disabling of apps designed to read actions on the screen".
Kasikorn's K+ has not required that for some time, the phone app operates even if the phone's security features are still activated.
"They have abandoned this policy, and replaced it with a simple test for every app user".
That has not replaced any K+ security features, it's simply an awareness test, nothing more and answering incorrectly has no consequences, it does not prevent access to the app. Other banks' apps have been showing the test also.
