no, You fanboys are all alike, so quick to defend apple when this issue does exist for a lot of people,,, but when I dial the call with 3-4 bars, then I drop the call while I am on it, it's at 1 bar.
I shot a quick video, Holding the phone in my left hand as I would as if it's against my ear, you can see the bars drop to 1, I let go towards the end of the video and they shoot back up. This time the call didn't drop but my previous test the call failed

My point is proven: 1. You were bear hugging that phone with your palm, people usually don't do that when on a call, I usually see people holding their phones with their fingers, as I do, lightly. 2. You didn't lose complete service. Your bars dropped, it's called attenuation and happens when in weak signal areas. 3. That call didn't drop, so if you weren't bear hugging it with your palm, it also would have been fine.
