I am experiencing a peculiar issue with my ZenFone 9, currently running on the Android 13 33.0404.2060.113 update.
The loudspeaker functionality does not seem to work correctly when I'm using either the default dialer app or Truecaller for phone calls. Strangely, when I'm playing music, using WhatsApp for calls, or even recording calls (where both parties are clearly audible in the recording), everything works just fine.
However, when I try to use the loudspeaker during a standard phone call, I'm unable to hear the other party's voice, which becomes quite inconvenient.
I've tested various apps and settings, but the problem persists solely during phone calls when using the loudspeaker mode. I've ensured that the issue is not tied to a single app, but it seems to be a problem within the system itself.
Here are the troubleshooting steps I've tried so far:
Despite these efforts, the problem remains. If anyone has encountered a similar issue or if you have any suggestions on how to resolve it, your input would be greatly appreciated.
I wonder if there's a specific setting or a hidden feature that I might have overlooked? Or could this be a bug associated with the latest Android update on ZenFone 9?
Looking forward to your insights.
