I tried HTC One
I've been using iPhones since the 3G and tried to make the switch to what seems to be the best Android phone available on the market, HTC One. I really like few things about the One that OP also mentioned including the design & build quality, excellent LCD display that's not AMOLED, and incredible sound from speakers.
However, after a few hours of playing with it, I easily noticed it does not respond to my touches (and multi-touches) and scrolls as well as my iPhone 5 does. I had few unintended touch responses from scrolling through and had to make more than one touch to get a response. Also noticed the OS overall is not as smooth as iOS which was expected before trying. Another thing that bothered me was that the fact I could not use it with and in one hand. I'm not sure how big screen can go for someone to still use it with one hand but it was a turnoff for me.
My wife also wanted to use a phone with a bigger screen than her iPhone 5 but quickly noticed the same thing - touch responses.
I wish I could install iOS on the HTC One to make a perfect smartphone!
I know it's impossible so sadly I'm selling it...
