Yes, but there are various annoyances that I was tired of dealing with:
- RCS chats not sending/receiving, which has caused me to not be able to receive or send messages from/to multiple group chats with friends/family (probably going to be an issue with GrapheneOS, but at least plenty of people have reported that to be possible to work; currently doing the "disable RCS and wait 10 days" dance, so we'll see how that shakes out)
- Every other reboot the speakers would fail to initialize, meaning I couldn't hear anything except through Bluetooth (massive problem for getting up in the morning if I'm relying on my phone's alarms!).
- Microphone quality was inconsistent; sometimes I'd sound fine, and other times I'd sound muddy. Also not an issue through Bluetooth; it was just the phone's built-in microphone(s).
These were probably fixable issues, but I'm lazy and I wanted to give GrapheneOS a go, anyway (and so far I'm pretty happy with it, minus RCS still being a work-in-progress).
