How often do you get a new phone? My Galaxy S10 from 2019 still kicks ass. It doesn't do any of the Galaxy AI stuff, and I'm okay with that.

I really don't think the 24 hour thing matters all that much. If it's the first thing you do when you get the new phone, and then you start setting stuff up, by the time you want to go looking for stuff to sideload, a lot of that time's down the drain.

It also begs the question of — and magnifies the silence of the lack of answers to a deafening roar — what actually needs to be sideloaded, let alone what is so crucial the 24 hours is any kind of a pain point. Worst case scenario, you hold onto your old phone for those 24 hours, before wiping it and selling it (or whatever you do).
