Thats too bad. I dont plan on buying a new phone in , at least, 6 years so itll have to wait then.
I know fairphone might look to be slow on driver update, but afaik they skipped a few versions to go straight to android 13. And i also know they try to maintain their own drivers so they provide support even if the soc vendor doesnt.
Its a very complex thing tbh, but ill keep grapheneOS on my radar!
