STEPS TO REPRODUCE
1. Ensure android phone is connected
2. Receive a phone call
3. Wait for system freeze to end or app to crash
OBSERVED RESULT
Once a call comes in, there is a 5-10 second delay before the text and audio
notification appear on Kubuntu 22.04 desktop. For a few seconds, you cannot
close the notification or select any other app from the task bar. Mouse moves,
but nothing highlights or can be selected. After 5-10 seconds, you can dismiss
the notification and proceed with system usage as normal. Occasionally, after
system freezes, instead of becoming stable again, app crashes with brief
notification of "....kdedaemon crash". You can try to report bug, but I never
seem to have required files to send a backtrace (debian goodies installed).
EXPECTED RESULT
Audible ringing sound and text notification on desktop should be in sync with
android phone ringing. System should not freeze upon receiving a call. System
should not crash due to incoming call and the ensuing system freeze.
