Dropping calls is part of everyday life for my friends with the S3 and Note. They cant believe it when I tell them my IP4S has never once hung on a call in over 2 years. I did have it happen a couple times on my 3GS over a span of 2 years, but thats it.
In truth most of them just got the S4 because they read on articles it was better than the iPhone. Maxim, FHM, GQ all got paid big $$$ by SamSung to pump their phones. Now they're locked in and BEGGING for me to give them my iphone. Poor schleps. Most of them will be switching laterthis yr when their contract is up.
