to be fair, the Note7 was one of Samsung's most refined offerings in the recent years.
yes, it may still be riddled with bloatware but I would say there's still a fair bit of refinement and optimisation put into TouchWiz
most of the bloatware don't come installed either - it's a link that invites you to download the actual item from the Play Store (Google/Samsung).
yes there's still bloatware. yes they are still not at the stage we hope them to be - but there's definitely improvements
How do you know that without seeing code? Apps still close in background memory more often when compared to other Android devices. You see GAFers posting "speed" comparison threads with iPhone on multitasking and drive by posting laughing that Samsung = Android sucks.
Why are there two store fronts? I remember reading the apps link to Samsung's store, not Google's. On some Android phones, there can be up to 5 different app stores. Who likes this user experience? Unless users voluntary installed the software on their own, this action seems like shoving unnecessary software down users' throats.
I think nothing has changed aside from throwing more money at marketing by installing product display booths in popular retail spaces.
