Problem with speaker in Samsung Galaxy S6

[Zoelev]

I just bought a new Samsung S6 and it had a problem with the speaker. When making a call and using the speaker the other side would hear me cut off. They replace my phone three times! (all together 4 phones) all with the same problem and two other people came at the same time I was at the store with the same problem. I finally had to return the phone and now I'm not sure what to do. Has anyone else heared anything about this problem???

Are you using a case/cover over the phone? I'm almost sure removing it solved the problem in my own phone.
