Stable? I'm on beta 2 and I have EXTREME choppy audio from the speakers (but perfect from bluetooth), jittery apps (got a lot better since Beta 1), and most annoyingly a "hanging phone call audio."
I can best describe my last annoyance as this. During a phone call, there are apps (like YouTube) that allow you to listen to the media audio during the phone call, but at a much trashier quality. Good for audio with talking, terrible for audio with music. However, after I end the phone call, the audio quality is still the same. This would also happen on occasion on Android 12, but pressing the interaction button on my bluetooth headphones (as if I'm hanging up the call) would bring the music back where it's supposed to be. On Android 13, this problem persists until I restart.
Did they squash all of these bugs? And there are much more...they aren't at the tip of my tongue.
