I feel like the odd-man out. I have had no complaints about the Note 4, coming from an S5 and before that a iPhone 5, prior to that every other generation of iPhone and Galaxy alternately. I haven't experienced lag or edge gap or screen issues. My car stereo connects and the headphone jack and power button location are fine for me. I seriously did look for some of the initial complaints but just couldn't find any. One of the lucky ones, I guess.
I think there is a tendency in a thread with this title to attract more negative views--that is what is requested, after all....there are plenty of other threads, too. You aren't alone, and I don't think you're in the minority, either.
I am sorry but these threads always make me shake my head in disbelief...
People suggest that you Turn off this and that, disable this, disable that... its a 2014 flagship, if I have to turn things off to get a "usable" experience, its a piece of crap. p )
You don't have to turn things off to get a useable experience. If I wasn't someone who frequented fora and heard about lag, frankly it never would've occurred to me. I think the phone is fine as is. I got talked into turning off animations on my S4. I wasn't really bothered before I did. It made little difference after. The phone was fine both ways. As some have stated in this thread, I find the complaints of lag astonishingly exaggerated. Nothing about its speed bothers me at all, let alone moves me to declare it unuseable. And I think, too, some people apply the term loosely to most everything. I have yet to see a computer that does everything instantaneously. Is that lag, or normal operation? Someone mentioned lag in pulling up recent programs...if I have 9 recent programs to be displayed, is a phone entitled to a second to gather info and do that? I just tried it coming from a lockscreen, unlocked it, when straight to that--1 second is about what it took. Can we take into account that we may also have several other programs open and might be using a lot more memory at some times than others? That's just a computer and I don't find a whole second offensive.
As for animations, don't want animations? Turn 'em off. That doesn't seem like a horrid burden. Your view of what the default should be is merely different than Samsung's, and some agree with you. But the choice is yours and it's not a burdensome one. Android is about personalization and choice anyway. I imagine most people here spend about 100x longer picking out wallpaper and other personalizations. There are threads here showing that we spend vast amounts of time on such things. (me, too!!

) I'm wondering how much time we collectively spent picking out wallpaper instead of accepting the default. Or getting new widgets instead of defaults. Or downloading Firefox instead of the default browser, etc. How much longer does it take to make one of those choices turning off animations? A few seconds? Assuming I was bothered enough to do it, that doesn't seem so horrible.
