The same lag carries onto scrolling performance in many applications, and infrequently in every application after heavy continuous usage. The phone does not get too hot, mind you, but we do notice that after continuous sessions, it progressively begins misbehaving. Scrolling behavior in particular is behind what you’d expect out of an $850 device, especially after this has been one of Samsung’s weak points for years.
When compared to the OnePlus 3, we find that the Note 7 often neglects using its four cores as opposed to the OnePlus 3, which efficiently mixes up its core utilization when handling the same task. GPU profiling on the Note 7 makes it extremely clear that the phone leaks frames on several actions, even minor animations throughout the UI such as a WiFi network spinning circle animation. In some instances, we found outright damning displays of the Note 7’s occasionally-pitiful fluidity accompanied by the walls of green bars denoting serious difficulties pushing the frames through.
But this is not just a matter of opening or returning to your application sooner than on other devices, Samsung’s software is noticeably slower than that of competing devices in almost every action.
The stock keyboard still sees issues with split-second lockups, and the sharing menu on the Note 7 often leaves you waiting for options to load. The notorious TouchWiz Launcher has earned itself a reputation for slow speed and stutters throughout the years, and while it is not as bad as it used to be, it can still miss clear frames while switching through homescreens, and despite years of integration, Flipboard still remains the most jerky leftmost homescreen panel ever introduced by an OEM.
I've generally seen better performance out of the S models than the Note models, the S6 seemed to perform better than the Note 6 for example and from what I've tried on the Note 7, the S7 is better there as well.
Maybe that's just me though.
