Wi-Fi calling not working on Pixel 8a

razorsedge
It is a workaround because I can at least still make phone calls with Wi-Fi calling disabled. I am hoping this will be fixed once the GrapheneOS version for the 8a is out of prerelease.

This is my first time using grapheneos, is there any kind of release cadence?

We have a prerelease available for the Pixel 8a which is not current GrapheneOS with the latest features and has limitations. It is not up to us to change that but rather AOSP and the stock Pixel OS need to move to current Android first. They're currently on Android 14 QPR1 instead of the current Android 14 QPR2. The last official release of GrapheneOS based on Android 14 QPR1 was before the March release of QPR2, which is what we had to use as the basis for the Pixel 8a prerelease. That means it's missing the improvements made to GrapheneOS in March, April and May other than a couple things we backported. It has the current May 2024 patch level but it's essentially the February monthly release of Android 14 QPR1, not current Android. It's unusual that it was launched with an older Android quarterly release and it's likely because QPR3 is right around the corner about to be released in June in all likelihood. It's premature to expect the full GrapheneOS experience on the Pixel 8a since the stock OS / AOSP is not the latest Android version yet.

1Dragoon The release notes are available at https://grapheneos.org/releases#changelog where you can see how frequent the releases are. Pixel 8a is not part of the regular releases yet and won't be until the AOSP / stock OS Android version catches up, which will hopefully happen with the June release if it's QPR3 (3rd quarterly release of Android 14) as expected.

I'm seeing similar issues, although it's not limited to voice calls: all networking functionality is extremely shaky.
When opening the WiFi network list, one can see that the connection is lost and reestablished every couple of seconds.
Similarly when disabling WiFi and trying to only use mobile network data transfer: it's all extremely unreliable.

Already tried factory reset and running without restoring the backup but that didn't change anything.
