Been using the Note 7 for a few days, the performance is pretty bad at times, and that's after dropping the resolution down to 1080p and turning the animations down.

 

Very nice device otherwise, but the frequent significant lagginess is really offputting.

 

Iris scanning is too fiddly to be useful, the edge menu is relatively useless, the screen is really nice, the audio quality over headphones doesn't sound right at all, might just need some settings tweaked.

 

The screen-off notes is really handy. Can't seem to get them to pin to the lockscreen, but I may have misinterpreted how that works.

 

The blue light filter is very nice.

 

Google Quick Search box seems to be hammering the CPU, need to work out how to shut that off. (Edit: Settings\Applications\Default Applications\Device Assistance App\ - Change from Google to None, disables the home button long-press and seems to make Google a little bit less CPU hungry.)

 

Enabling GPU acceleration in the developer settings seems to make the UI a little bit less laggy, might just be placebo.

 

That sounds like a phone that needs to be returned.
