I have sprint version and live in Westchester county /Bronx border. When in calls I experience some static and a popping every now and again. Only in call on speaker or earpiece, all video and audio playback is clear, so I know its not speaker related. I have done numerous hard/soft resets, tech support reset my network, updated profile/prl. Still the same, weird thing is, when roaming calls are crystal clear. Went to the sprint store today and they are saying its network related(don't really believe it) since my 4 year old has more knowledge than some of their CSR s. However I would just like to know if anyone else in my vicinity is dealing with sane issue? I also have iPhone 5s and HTC one that have never done. Any thoughts, help, would be appreciated.
