Overview

On devices running One UI 8.5, you may encounter an issue when making an outbound call while using the Samsung Dialer app in Kiosk mode. The app briefly freezes causing the device to crash and automatically restart.

Cause

Due to compatibility issues between One UI 8.5 and Android OS, the Kiosk application exits unexpectedly when you make an outbound call using the Samsung Dialer app. This causes the device to restart.

Resolution

The Samsung Knox team is aware of this issue and have scheduled an update for all devices running One UI 8.5 in an upcoming release. We recommend you update your device firmware.
