I think it's very healthy that people will look for alternatives to Apple products. It's not an easy thing to do, because Apple has very successfully created an entire "ecosystem" in which everything plays well. Once you try to add a non-Apple component to your life, things can get complicated. It's very funny, because Apple used to be the one crying "interoperability" when Microsoft dominated nearly every aspect of consumer technology. Now it's the other way around.
Anyway, I've frequently used non-Apple products, partly because they just did more of what I wanted, and partly to make sure I was sufficiently competent in a broad range of technologies (for professional as well as personal reasons). For example, I'm currently using a Blackberry Q10 in addition to my iPhone. And I'll be using some kind of Android device soon, too. And I might even swap my old Symbian-based Nokia phone for a Windows Mobile of some sort. But all of these have problems, too. Sometimes it's stuff like this photo-sorting problem, where something on the platform just doesn't work. Just as often, it's a problem that an app that you depend on just doesn't work well (or even exist) on a particular platform (that was a problem for me migrating from PalmOS to iOS - and try migrating *off* iOS if you want some fun).
But if more people would be driven to try non-Apple products, it will have at least two important benefits: (1) it might just persuade Apple to fix some of the nasty problems (another big one is the space consumed by "Other" on iOS devices - no solution in sight); and (2) it will help people to avoid the "religion" disease that so many people develop for Apple products, where they become blinded to the fact that Apple products and support aren't perfect, and that other companies that previously ignored customers have evolved (e.g., Microsoft).
Don't expect a solution to the photo sorting "problem" - ever. In my opinion, it's not a problem at all, but an accidental but inevitable consequence of coming architectural changes in the management of content on iOS (and Mac) devices. A word of advice: if you don't want to be pushed over the cliff that we are approaching where you will be forced to use iCloud, Apple Pay, and a whole bunch of other coming features that will lock you into Apple way beyond the price you paid for your devices, you should start seriously thinking about using products that run other platforms. There are a lot of good ones to choose from, including Amazon, Microsoft, Google, Facebook (well, they're not so hot - the phone was a dud, but still ...), etc. Even Blackberry isn't dead, yet (but they're "circling the drain", as the saying goes).
Apple is well aware of the situation. My guess is that they were aware of it in the design phases of the current Photos app, which goes back probably two years. Instead of worrying about what's broken today, you should worry about what's in the design and implementation phases today, because this is stuff that's *really* going to **** you off in another year or two. And if you don't have an exit strategy, you're just going to bend over and take it.
