I was playing around with my 3 XL last night and really have to reiterate widgets on Android really suck. It's comical because I used to stand up for Android in large part because of the widgets. But they just seem so disjointed, really bad looking with titlebars that are too thick and haphazard functionality. Plus there is no common design language, which I'm surprised Google would allow, colors, fonts, sizing, functionality and even just the way they fit onto the home pages is almost completely different from widget to widget, plus you can't vertically slide a home page so can't have all your widgets on one page. I was reading through some dev forums and apparently it's a pain to code Android widgets for many reasons. I am seeing very few widgets on Android for my most used apps, I see a lot more widgets on iOS which is a weird reversal from a few years ago.
On a good note I found Google has been slowly introducing dark themes to some of its apps, although the effect is inconsistent and really odd in that some dark mode apps such as Google Feed open into non dark mode apps such as Google News and Chrome. For web browsing the Samsung browser is absolutely the best because it's Night Mode actually changes webpages to become dark, very nice.
