I don't know from what market you're getting your products from, but I've never had a phone that had reception problems when holding it in the left hand.

Of course, I've only used low-end Nokia phones mostly, and smartphones might have problems in general ... but you know, that's why I purchase a phone mostly ... to make phone calls ;)

And when you're paying several hundred dollars on a smartphone, or getting tied up with a multi-year contract with AT&T ... you are expecting that smartphone to make phone calls fucking reliably (even more so than a $15 Nokia phone)
