Audio switching to internal speaker during WhatsApp calls

Okay, you might be right.. My app was installed for 2 years I guess on my phone, and maybe that's what made it buggy. iOS update was also performed on top of the installed app. So I will try to remove the app completely and then download it again from the store and see if it helps.

So I reinstalled WhatsApp completely and it didn't help. However, for now what seem to fix the issue at least in some extent is disabling Headphone Safety feature. Which doesn't make any sense cause I don't have problems with audio when my headphones are connected. Can you advise, what can i do in this case? I doubt that sending any feedback will help here. And I also don't want to disable that headphones safety feature...

But again maybe it's just an assumption cause sometimes i get this volume bug when i switch off my screen to just listen the audio and it becomes mute.

Also, quite repeatable bug is when the audio is playing, I lock my screen, it goes black, then I tap to wake up my iphone, the screen gets unlocked and the audio gets mute (very quiet). Only if i change volume and then restart the audio it again plays at normal volume.

Okay like i said it seems to be an iOS bug, not WhatsApp. Cause recently i encountered the same with TikTok and it also random. When i unlock my screen and swipe to switch to the open app it can randomly start sounding quiet and changing volume with buttons doesn't do much. Exactly the same which happens with WhatsApp....

Yes, my app is updated to the latest version. However, the issue been around since iOS26 update I believe. I didn't contact Meta support on that cause I'm pretty sure it's on the Apple side. After all, I don't think I'm such a unique user to experience this bug alone on the planet, since I use my phone normally as any other user. It's just that probably other users never switched apps during the call or listening to the audio message, so they didn't pay attention.

"Their notes for the last update introduced a new feature involving switching audio" - if this was the reason then it would start recently, but it's quite an old bug. I just got too much annoyed of that and decided to finally ask....

I guess you're right, since I don't use any uncommon settings for the app or my phone to produce this bug. Also it's pretty random and may appear under different conditions. Let's see if they fix it in the upcoming months.
