I created my account a while ago when I still had my Samsung S5. About 4 month ago I bought the Samsung A8, downloaded the app and used my credentials on it. I worked fine for about 2 months.
Since 2 months, after listening to my favorites song for more than one hour offline or online I will hear some background noise (like the wind or if somebody would crinkled a sheet of paper). Once the noise starts I will have it on all songs I will be listening.
I did delete and redownload the app but it didn't fix the issue. I am using the free version.
