As someone who has a profile only for Whatsapp (used to also be Instagram), a profile for banking & finances, a profile for some stuff that needs play services, and a profile for most other stuff (main profile)…don’t use profiles unless you’re only creating one more at the most, and you’re absolutely certain there’s no need to share information between the profiles.
Graphene has had a long-standing bug from upstream AOSP, if I recall correctly, where it’ll always ask for your pin when changing profiles, and only sometimes will it allow you to use your fingerprint or alternative methods to get into your profiles. I almost never get the fingerprint option for my main profile, and have to tap back from the pin input on other profiles to get the option to use fingerprint, and not always. They do sometimes push something that loosely resembles a fix, but it’ll go back to not working after another update.
Regarding communicating between profiles, that’s hard to pull off. The curveball of having to send screenshots from banking apps, say, confirming transactions, it’s made a lot worse with profiles. I’m currently relying on my nextcloud instance to upload screenshots from finances, then downloading those screenshots from nextcloud into my WhatsApp profile, just to send a proof of transfer to someone. I’m definitely not keeping my phone like this for much longer.
All else considered, however, I’m not going back to a ROM that doesn’t respect me as the owner of my device. I’m happy to have switched to graphene and I am here to stay.
Wooooosh
