I have not any prior experience with installing custom ROMs, but after trying it out (and getting stuck, and googling and finding answers) I successfully did it. Below is my home screen if anybody is curious:
I use OpenBoard for my keyboard. Unfortunately I am still dependent on Play Store since some of the apps I need can only be found there. Sometimes it feels meaningless committing to this whole thing because I'm not perfectly private; then I think this is better than using a regular iPhone or Android phone.
So far I'm liking it. I am naturally inclined to feel hesitant about using this as my main phone and plugging in a SIM since it's custom, but I'm slowly making the transition.
Feel free to share any beginners advice or your own experience using GOS for the first time. Cheers!
Its also worth noting Graphene's focus on pixel devices stems from those devices having more easily secured hardware. Which android fork you decide to use will depend on your particular use case. I wound up going with a Pixel and Graphene for android auto. But if you're someone with existing hardware that you want to set up with a degoogled os, there's e/os, lineageos, CalyxOS, iodé, and, if you wanna get really weird, postmarket os. Having done a deep dive into this I can honestly day there's no single OSFA answer to this.
I did not realize there were other forks besides Graphene and LineageOS.
In any case, thanks for the info. I guess I'll have to shop around.
