I just...*headdesks with laughter*
My phone's cheapest prepaid plan is $45 through GoPhone, aka AT&T PREPAID (allcaps are theirs, not mine). I don't, to say the least, have $45 for anything, much less my stupid phone, but we're getting into storm season, I still fear the trees and I happened to drop my LG flip phone - which I kind of fucking adored in all its 2G glory - in the toilet the other day and the 3G replacement is such a dud I plan to throw it off the next bridge I come across.
Besides my Windows phone and my bridge-bound dud, I have a tiny Android I haven't used in literally years, so I called Net10, who services it, to ask about plans. Their cheapest is $35, saving me $10 bucks, so I took it (data went from 6GB high speed with rollover to 2GB without rollover; other than that the plans are about the same) only to realize I had to migrate my Windows phone data to Android - mostly contacts, photos and emails (I could be upset about losing call logs and texts but I'm really not, so I haven't sought to restore either one of those).
As I write this Google Drive, aka Backup and Sync (the name change is theirs, not mine, sans the allcaps) is syncing 9,655 files between my laptop and their servers. I decided my folder selection was too aggressive when GUID diagrams for Firefox and my Dell printer began rolling in but whatever. To get this far I had to uninstall Google Drive after merely "upgrading" it to Backup and Sync, which failed miserably, not allowing me to sync the proper folders and basically fubaring everything.
While I was unfubaring the laptop installation, I rolled back Drive on Android to factory-installed settings and broke the sync connection from my laptop, which wiped out all the files on Android's Drive. There weren't many because the Gmail address I use for Android was not talking to the one I use on my laptop so I logged out of GMail on my laptop, logged back in using my Android Gmail address, then re-installed Drive (now Backup and Sync) on my laptop. This installation went flawlessly and is syncing away as I write this - and slowing my connection to Dreamwidth to a crawl.
When it's finished, I should be able to upgrade Drive to Backup and Sync on Android and pull in files from my laptop, which should bring over my Windows phone data, because I threw my OneDrive folder in there and it actually let me, which I cannot believe. Getting that done should pull in all the photos on my Windows phone, which are the only data still missing after the work I did last night to pull in everything else...
First I imported my main Outlook account to GMail, but the import was marked "has not started" with a "provide info" link that made me log in again in a small, separate window that barred add-ons like LastPass from running, then told me my credentials were incorrect although after triple-checking them against LastPass I could see everything was correct.
So I googled these problems and import will probably never finish based on others getting the same error messages since literally 2009, so I moved down the list to Send Mail As and Check mail from other accounts. Those tasks went as expected, so now my Outlook mail is forwarding to GMail on Android, so I'll never really need to check my Windows phone again. I also have a setting that shows what's coming in off Outlook - but according to the unlabelled emails I'm getting at the moment, it's at least partly malfunctioning, so I'll need to fiddle with that some more.
Once that was done, my Windows contacts synced with Android and GMail started receiving Outlook mail, so things were getting better, but I don't like stock Android, so I was in need of a more ideal solution when I stumbled across Arrow Launcher, which uses "pages" in place of launch icons or home screen widgets to let you see email as it arrives (you can use app icons or pages, but pages are amazing) so I set up an Outlook page as my second home screen (just swipe right) and now I don't even need an app to scan my email (though I still need an app to read the body text).
Unlike any Windows app ever, it doesn't crash (well, it crashed immediately after installing - um, it not only crashed, it removed all my custom settings, but after a phone restart and a redo of all the settings, it seems to work just fine).
To get around Android's ugly stock app I'm using Android Messages; I tried Allo but it's too resource-intensive, so I had to remove it after only a few minutes. That I can't update from Jellybean to the current version is irritating because I want the Ibotta app, which so far is the only app that isn't compatible, but I haven't really "done" apps in my rush to get Windows data onto Android, so I guess I'll see what else fails to play well with it eventually.
