========================================
When I am having a call with anyone (even using internet call or normal cellular call). and I turn on my speaker mode, my Zenfone 8 will have very loud echo sound until it is very hard to bare.
I have test voice recorder and speaker, all was ok and even tested at in calculator apps with .12345+=. everything was fine.
I have just bought this phone and barely even use for few week and started using it and this occur 😥.
right now I am still finding ways to rollback to android 11 and hoping that is it software problem.

thank you.

Test how it works on your side.

Of course. I wrote above that it has been fixed by authorized service center (by warranty).

Just friday I got my zenfone8 from warranty, they changed subboard, but problem is not fixed. I was without my phone for a month and the problem is not fixed. What I should do next? I like this phone, but with this echoing is useless, because all my calls is on loudspeaker and nobody can talk with me

I always say to the people, that now I'm gona use hand mode and they will hear huge echo, but I'm telling them just to don't pay attention for this and keep talking. Worst thing is that microphone sensitivity is very bad and i have to yelling in hand mode.

First time I received phone from service - it was the same. THen I complained to asus customer service and they asked me to send phone to service again with control from their side. Second time I received phone from service - everything was good with MIC. 🙂

Well, I also had my problem not fixed after first repair (even that they changed motherboard). But after that I contacted with ASUS (wrote them a complaint) and send phone for repair second time. And it was fixed.

I recommend you to contact with ASUS support and ask them to control your (next) repair. At least it helped me with my repair here (RU).
