I just bought a Tab S4, upgrading from the S3. The Samsung notification sounds override all my app sounds. Is anyone else experiencing that? Is that normal? I don't like it and want to find a way to stop that. I do not like the notification sounds that are preinstalled with the Note S4 and don't want to have to get used to a entirely new set of sounds. Thinking that I should do a factory reset as this doesn't seem right.
