Hi, I recently bought a Samsung Galaxy Note 4 and I'm not sure if it's faulty. When I play ringtones (or other media), the speaker sounds really rattly/distorted. It's particularly noticeable when selecting the Quantum Bell ringtone. This happens with the volume at 50% or above. Does anyone else have this issue? It's probably just the way the speakers are but I thought I'd check whilst I am still able to return the phone. Thanks.
