&gt;  Despite how fast Tegra X1 is, and the fact that the SoC is seemingly always using its A57 cores, the interface can be quite janky at times. Normally things perform fine, but both Josh and I have observed random lag and frame drops when doing basic actions like scrolling, opening apps, and bringing down the notification drawer.<p>This is aggravating to no end. Top of the line (mobile) hardware, years and millions of dollars in engineering effort, and perf still sucks. I&#x27;ve tried very hard for years to be charitable about this problem: programming is hard, and there are a lot of smart people working on this.<p>But something is fundamentally broken with Android&#x27;s abstractions. I don&#x27;t know enough about Android&#x27;s architecture to say what it is -- but there is no other reason for perf to still be a problem [1]. Every Android device I&#x27;ve owned has had these issues, while my $45 Nokia Lumia Windows phone has been consistently responsive for over two years, on marginal hardware. What the hell is going on here?<p>[1] Either that, or critical code paths are being bloated with unnecessary features faster than the runtime and hardware are improving. Which would still be surprising, because that has to be a <i>lot</i> of bloat.
