Have had my Note II for 3 weeks now and have really enjoyed this new device! (Coming form an HTC Thunderbolt) However, my Note II resonates badly using mid-range and higher vibration intensity. Any time the phone vibrates now it sounds like a plastic rattle trap. Its sounds as if the plastic back is rattling loose even though it is very snug in place. I also use a Seidio Active case and it makes no difference if the case is on or not. Just wondering if anyone else has noticed this? It literally makes the Note II sound cheap.
