GrapheneOS I had a strange occurrence today. I recently installed an eSIM from a new provider. Doing so required installing play, services, and GSF. I did not uninstall them right away, not wanting to have to devote time to any untoward events that might occur (signal acted up, reasserting the message about push notifications, upon install, IIRC).
Today I uninstalled them, as the eSIM supposedly remains once installed. I don't think I messed with any other settings on this phone, but this afternoon I had severe lag in sms, with it saying unable to send to single recipients, then finally sometimes releasing, but no MMS capabilities, at least unable to send to multiple recipients. I forgot to test sending a picture. I reinstalled, everything worked. Disabled. msgs work fine. Re-uninstalled, everything working so far. Unable to uninstall GmsCompatConfig dependency, only disable. Not having looked for it before, maybe I don't want to do that.
Of course it could be non-related, but running the new eSIM and service for nearly a week I've had no problem until now, and never had any hiccups with a year or so same phone on another carrier. 3a, FWIW.
I apologize that this is sort of a hijack of the thread, but it is older now, and your comment is most in line with the knowledge I am looking around for.
Thanks
