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

shouldn't the signal drop happen a little faster than that if it were in fact from the death grip? You don't think it could have anything to do with all the stuff running around the phone like your computer and the camera creating some interference?
I know nothing about cell signal so I am asking these questions seeking a legit response. If the answer is "no" to both of those questions then that might worry me.
