I have been using Hail with Shizuku for removing most of the Samsung and Google apps, replacing them with Foss alternatives but I would love to know that when it’s time to retire this phone or I stop using Google services, is there an easy way to install custom ROM on this phone?
Please do let me know.
If you are unable to install a custom ROM on your Samsung smartphone, the next best alternative is probably to use https://github.com/0x192/universal-android-debloater to deactivate as much Google and Samsung spyware as possible.
I use Hail with Shizuku for debloating.
