Looking for solutions to delete/opt out as much as i can from GAFAMs and other chinese closed-sources stuff … im a noob and i feel lost right now … would this be a good idea? https://gitlab.com/W1nst0n/universal-android-debloater/
Or should i think about Lineage OS or similar ?
Your phone is listed as unofficial build for /e/ OS. /e/ is based on Lineage OS and pretty much de-googled https://e.foundation
In this list you can find your phone: https://community.e.foundation/t/list-of-unofficial-e-builds-part-2/18956 An unofficial build is essentially a build from a member of the community I have no experience with this build, so check before you use it
