Im on the pixel 7 purly cos of size. Graphene has been great turning mic and camera on and off can get a little tediouse but u dont have to use that feature if u dont wanna bother. Accessing the same file from different apps can be a little anoying sometimes due to sandboxing but nothing too seriouse. Took me a while to set things up how i wanted custom launcher, keyboard, fdroid etc but im very happy now no issues at all, ive heard people saying some apps like bank apps etc dont work i have never encountered this issue google servuces conpat works perfecrly. Well except for android auto but a recent update suposidly fixed that i havnt tested yet. Its development seems very active u can get a rundown of updates as they come out here !grapheneos . Im never going back to a proprietery os without the security features graphene offers ever. U might wanna check out the alternatives tho ive heard good things about LineageOS as well. Only thing u might wanna watch out for with graphene is the dev/s have mad beef with practicaly everyone.
