I switched from iPhone to Android and I was fully expecting a world of pain but I was (am?) pleasantly surprised.
The back button thing is real. When I have to use someone else's iPhone I immediately feel the lack of consistency.
And KDE Connect is fantastic to use. So many things on iPhones are just annoying for no reason. I don't want to buy a 1000 dollar computer to look at my photos, come on now.
PhotoSync and LocalSend.
I'm not too big of a fan of KDE content but totally get why people use it.
I do want to suggest you install termux, and do it from fdroid rather than the play store.
I'm guessing you're on Wayland, so check out ydotool. (If still on x s/x/y) there's a lot of cool things to do with tools like that. Basic one is use your phone as a keyboard (like KDE connect can do, but I found it more reliable and KDEC doesn't play well with VPNs)
I wrote a similar script in Apple Shortcuts and... wtf is this bullshit. My files backup Shortcut is even uglier. I'm incredibly impressed at the hacky shit I was forced to do just to backup photos... I almost would rather pay for an app that does it. I almost would rather learn how to write an iOS app. Just to... replace a 10 line bash script -__-
Since I'm still not a big fan of Google my next phone is going to be a Pixel and I'll install Graphene on day 1. That is, unless something better comes out :)
