Is Samsung security Invalidating "Android Keystore"?

Hello,

I have an app that store keys to Android keystore and its used in some kind of authentication by my apps. There have been few incidents where whenever there is a security update from Samsung on there devices and right after when my app tries to access the same keys(my app stored) from Android Keystore, I get “No key found” exception.

I then have to re register the keys again and re-use it.

I am wondering if there is some kind of bug in Samsung security updates that it tinkers with the Android keystore, possibly wiping it out or accidentally deleting something in it.

I have confirmed with my telemetry system that I have issue ONLY on samsung devices not any other devices. S24/S24 Ultra seems to be mainly impacted.

Please provide some guidance in this case.
