Loose parts?

i dropped my meizu just now and tested it out and it was fine. however, i shook my meizu to see if there were any loose parts and to my surprise i hear a little loose piece that i didnt notice before. of course, i never shook my meizu purposely before. so i was just wondering if u guys would be so kind to help me out. just shake ur meizu for a sec and see if u can hear the SLIGHTEST little piece shaking inside. i wanna know if i damaged something or if its normal. thanks

yeah i hear something but i think its the little stick for the strap
