For processing, I can say that HTC has apparently extremely improvement! I have absolutely no gap dimensions, the phone looks solid and high quality.
Only the headphones I have a small degree, this can be removed with a sharp craft knife but quickly.
The rate is as might be expected with a 1.7GHz quad-core course outstanding! As well as the built-up camera. This is only slightly worse than the Galaxy S4 but who knows the camera from the Motorola Milestone 2, for which there is a quantum leap. Even in the dark makes the camera for their aspect ratio still decent pictures.
Incidentally, I am permanent users, so the mobile phone is from me right "tortured". I had previously no stuttering, problems with apps etc. So everything works exactly as it should.
All in all a great phone and I also hope the service life of min. 2-3 years make it without major problems.
PS: If anyone has a recommendation for the purpose car holder or dock, may contact me to I can so far not yet the right decision.
