I want to go full open-source with my phone, which is why I use Lemmy instead of reddit, there are a lot of proprietary built in apps that are bloat and are of course, not open source, Samsung does not let you disable or uninstall any prebuilt apps, any ideas?
If you want to gradually move away from closed and/or paid software, afaik, the only way is through unlocking the bootloader and uninstalling programs through there.
Alternatively, there is the nuclear option, to replace the whole system, and start from zero with a distro as close as possible from AOSP. Worth noting it also requires unlocking the bootloader.
This is what I would recommend. LineageOS is great.
But if you’re aiming for 100% open source, you should account for stuff like radio firmware. You’ll have to look at Pinephone or Fairphone. Android contains a lot of binary blobs.
