I have been missing many calls from my Hero more than any other Sprint phone I owned, has anyone experienced this issue ?? not even a ring, full bars of signal strength and goes to voicemail at times, not all the time but my wife says it happens a lot when she tries to contact me, any suggestions folks ?? I read some stuff about the Slot Index would this solve my issue?? or would I be best to root my phone since I am still stock??
