galaxy s4 rattling sound..
Hi there. I bought a galaxy s4 3days ago and noticed that there was a loud rattle noise when the phone is shaken back and forward. It happens even when only slightly shaken. Sounds like there is something loose near the top of the phone. I returned it to the dealer and they gave me another one. The rattle even worse on this new phone. It also sounds like speaker is distorting slightly when i make or take calls. I was just wondering if anyone els is experiencing these issues or if i should take this phone back to the dealer also. Thank you
