Android phones are sending significant amount of user data with no opt-out [pdf]
I use GraphineOS and LineageOS without Google Play Services. They are great and are suitable replacements for Apple and Google.- Osmand(FOSS) for maps (supports being fully offline!)- Signal and Discord for messaging (Discord is sandboxed)- Newpipe(FOSS) for Youtube- F-droid(FOSS) for my FOSS appstore- APKmirror for the few non-free apps I need- Libretorrent(FOSS) and VLC(FOSS) for watching movies- Firefox(FOSS) and Vanadium(FOSS) for browser- K9 Mail(FOSS) for email- Infinity(FOSS) for Reddit- Secur(FOSS) for 2FA- Taskkeeper(FOSS) for remindersAlmost everything you need is in the F-droid FOSS app repository. It all works, and it works well. You can buy a used Pixel 3a for around $80 on Ebay and have a better experience in every category than iOS, hardware and software.The only limitation is push notifications, which isn't a problem because FOSS apps like Signal bundle their own notification system that does not use Google Play Services. Discord however, does not get push notifications (which I wouldn't want anyway)
