I'm struggling with a love/hate relationship with my new Apple iPhone 4. See...it's pretty. Really pretty. But making calls, that's not working out so well. You've probably heard of the signal strength woes when you hold the phone a certain way. But that's easily fixed: get a case or hold the phone differently. I'm actually ok with this issue.
What I'm not ok with is the call dropping issue. And I'm starting to think it may not be the antennas at all.
Since I started counting, I'm averaging 8 out of 10 calls just completely cutting off. But I noticed I'm not getting the "Call Failed" screen you normally see when the call...you know, FAILS. I've also noticed that my cheek has hit the mute button a couple of times during a call. The screen is supposed to be off when it's smushed against your face to keep you from pressing buttons.
So this leads to my theory that it's actually a faulty proximity sensor (which some people have already noted, having issues with screens not turning off in general) causing the dropped calls. A bad proximity sensor could keep the screen from turning off (or staying off) during a call. Of course, when the screen is on, the buttons are on and your face becomes a giant finger...capable of hitting the "END" button and killing a call. Which would also explain the mysterious absence of the "Call Failed" screen.
I wanted to document my brilliance in case it turns out to be true.
