It really depends which edges you find rough. Maybe we don't have the same needs. I try to use mostly open source apps and sync my calendar, contacts, files, notes and podcasts via Nextcloud. I use sandboxed Google Play Services for the small handful of apps I need but can't get any other way, everything else comes from the various open stores like F-Droid, Aurora, Accrescent, and Obtainium.

I've used countless ROMs over the years, as well as stock android, AOSP, cyanogen mod, later lineage os., caylx etc., without google, with microg etc.

Honestly Graphene is the first where everything just worked, and gave me the option to take or leave google apps, and have them in a sandbox if I desired.

Probably the first time I haven't felt the need to root or install magisk modules to customize behavior.

For me it's like having your cake and eating it too.

To be honest, and this probably seems minor / trivial, but one of the only things I miss about using GOS is the ability to turn on the flash light by holding the power or whatever other button.

I'm curious about the rough edges you experienced.

All my smartphones had been Samsung, and then I bought a Pixel just to get GrapheneOS and for me it's a way nicer experience, so I'm curious what the rough edges are that you experience?
