I have this phone for over 2 years and until now the HTC M10 looks to be winner over him. I do format my phone at every 6 months to keep him better. The only thing that I hate is the battery and nothing else. It's a great phone even after 3 years!
This is the miraculous piece of completeness that will never be repeated again ( metal body, dual ACTIVE sim, OIS ultra pixel camera, ultra-durable, boom front speakers, Beats audio.) . Miracle by the mean of the word.
