I just switched to AT&T two weeks ago when the Nexus first launched, I couldn't believe how many dropped calls I had (14+ in a week!) It was pretty shocking because I had close to full service consistently. I talked with friends and family who have AT&T and they all said they never dropped calls. I switched to the s3 and haven't dropped one call in a week. Friends who have the Nexus have mentioned the same problem. Is anyone else having the same issue?
