Can you please stop putting sensational titles in your notifications? Unless HTC is going out of business a review about their latest phone does not entitle a title : "HTC is toast: This is the last nail in their coffin".
Starting to treat these articles like spam and will unregistered if it doesn't stop!
Those buttons must be really really bad for an otherwise outstanding phone to get 6/10. 30 minutes battery life is not a huge amount off the galaxy and as you said... The screen is more colour accurate but not as vibrant. The idea of the buttons sounds good. Perhaps the settings just need tweaking.
Sounds to me that if you are hitting the power button while trying to user edge sense that is a You problem. This is clearly user error just like all the other reviewers who can not activate double tap using edge sense by lightly tapping. It's pressure sensitive so a tap doesn't work you need to press!
Who holds their phone so far up that you are at the power button. What we really should be complaining bout is Samsung. The power button opposite sides of the volume rocker. Now that is bad design. Trying to adjust volume and accidentally pressing the power button at the same time because of its location.
