Poor voice quality

[qualinn]

I have this phone from yesterday and I have notice that voice quality during phone calls is very poor 😕
People in their phones also told me that their hear me not to good.
Is it normal for that phone? Cheaper phones have better phonecall quality like this one. Im very dissapointed 😞

I am the owner of zenfon 8 from May 26. I can confirm the very poor quality of the telephone conversations. It uses the Plus and T-mobile networks in Poland. In Poland, over 90% of calls are of Hd Voice quality, but Asus does not support this quality. Please help.
