Samsung Galaxy S25 FE WhatsApp Video Call Volume Too Low

For about a month now, the audio on WhatsApp video calls on my Samsung Galaxy S25 FE has been coming through at an extremely low volume on my end. When I make a regular phone call with the same person, the volume is perfectly normal — but the moment we switch to a video call, the audio drops noticeably and makes it genuinely difficult to carry on a conversation.
I've tried uninstalling and reinstalling WhatsApp, restarting the phone, and checking every audio-related setting I could find, but nothing has made any difference. Because of that, I believe the issue is rooted in the device itself or its software.
I'm requesting that Samsung investigate this issue, release a software update to address it, and permanently resolve this low audio volume problem that affects WhatsApp video calls.
