Horrible sound crackling/stuttering on ZS630KL
The sound is definitely not normal. As exemplification, I'll talk about whatsapp audios for instance: the more audios I try to listen (as if in a normal conversation), or even the longer I keep listening to the same audio (like 1 min length), the worse It gets, almost like a cumulative lag.
Below, there is a .mp4 file which holds a recording of my screen and shows exactly what I am talking about.
What is this?? Should I just return It? The phone arrived only 2 days ago.
