I've been waiting for this phone since I first caught wind of the FCC filings, and don't get me wrong, I love it, but there is one major gripe I have being a left-handed person... - the fardling sensor that detects if you're phone is near your face is on the top-left side of the screen. This means that I cannot hold the device with my left hand and interact with it while on a call. Trying to use my left thumb to swipe the notifications bar down will cover that stupid sensor for just a second, shutting off the screen. Additionally, because the sensor is so sensitive, the shadow my left thumb makes while holding the phone is often enough to cause the screen to turn off. Until I figured out what was causing the problem I thought I had a totally possessed phone as I fought with the phone to turn the phone off mute with my thumb during several semi-important / mostly-boring conference calls where my occasional grunt of acquiescence was required. So, there you go, my one fatal design flaw that I have to "live with"...for an otherwise amazing device.
