Flashed my Android phone with Lineage OS without any Google Play Services — most apps work OK, though have some teething issues (some probably based on my config). Find any google things I still need I can use the web version for.
* some apps crash on start-up, even though you'd expect them not to be using Play services. Others (e.g. Monzo) work fine but I no longer get push notifications.
* some e.g. (Citymapper) work really well apart from the Maps integration, which is fair. Would love if devs could provide a fallback to link out to another maps providing app for directions but know it's not financially viable.
Maps.me wrapper around OpenStreetMaps is a really nice replacement for GMaps — like that I can correct things on it too. Only issue is that address lookup is slow & house number level info is a bit lacking. In London though, street level is good.
Moving cloud stuff is slower going — Have mail forwarding to Protonmail & will start to put an auto-reply on emails asking people to use new address directly. One thing I'll miss with GMail is the "send as" feature for other email accounts — use it a lot for things that are jointly between me & my wife. Also wish I'd have used a custom domain before switching so that I could swap vendors later more easily.
Need to pull photos & docs and create a backup somewhere. Not sure what vendor I should use for that.
