Just bought mine today. I just want to preface this post by saying I think it's a really great phone overall. But it's not perfect:
- It's an absolute fingerprint magnet. The back constantly looks 'dirty' with fingerprints.
- Samsung's Touchwiz software I have to say feels quite slow when compared to the HTC 10 or Nexus 6P. Seems to have delay when opening an app or going back to the home screen. Also notice stuttering when swiping across screens, pulling down the notification bar, and just generally navigating through the UI. It's not big or distracting, but it's just not as fast as the HTC 10 for me.
- The speaker is quite poor. Sounds muted, as if someone is covering the speaker with something.
- I don't like how there are so many duplicate Google and Samsung applications. The phone looks bloated with two sets of apps: 'Calendar' 'Calendar', 'Clock', 'Clock', 'Gallery', 'Photos', 'Messenger', 'Messages' etc.
- I don't like that I have to create a Samsung account if I want to use any of the Samsung stuff. I just want to download a different theme....don't see why I need to sign up to a Samsung account....
