  • Graphene OS intermittently fails to ring for incoming calls

I am experiencing a very similar problem to what is mentioned above, Pixel 7, AT&T. Certain incoming phone calls not appearing at all. Outgoing phone calls and texts going through; but randomly getting delayed batches of texts (7 texts or so around a day later).

donotworrybehappy This has been happening to one of our Pixel 7s very intermittently. When it happens, outgoing calls on that phone cannot be made either until airplane mode is toggled on/off. Is that the same for you or anyone else replying here with similar symptoms?

We don't have the greatest reception at home so I've chalked this up to carrier problems until now, but I'm definitely curious.

    Has anyone from the graphene team responded to this thread? Seems like quite a bit of anecdotal evidence of some type of issue…

    While I’m not aware of this happening to me, it’s also the type of issue where you may not realize it’s happening if it’s intermittent and the other party (person calling texting) doesn’t tell you about it

    Earlier in the thread, someone said that disabling wifi calling seemed to have fixed the problem for them. The people who said they'd try and report back haven't done so, so maybe it worked for them. I suggest anyone else who has this issue to try that as well. That or try other things to see if they can figure out a fix.

    I'm disabling WiFi calling and will update no matter the results.

      Have the same issue, it happend back in december but stopped at some point when i got a new provider, then it started happening again withing the last 2-4 weeks. im at a point where 50% off calls don't come through and have to revert back from graphene until this issue is solved.

        applesbana Yea i noticed now i must have missed that reply. My bad. but kinda make it suck more since then i have no option until google fixes the issue.

            I’ll admit, I keep my old iPhone as a backup for situations like this. Google hardware has been finicky for me over the years from battery life, sim issues, and fingerprint readers

                Seeing GOS release notes about CarrierConfig2 app, but I can't find it in the GOS "Apps" application. Has anyone tried using CarrierConfig2 instead of the Google CarrierConfig? Would that potentially fix the issue?

                applesbana applesbana It's not a Pixel or GrapheneOS issue but rather a carrier or app issue. It could mean the carrier lacks reliable VoLTE support when it's being used. For apps, it's generally caused by having a broken configuration without push fully working. For example, Signal or Molly without Play services with unrestricted battery usage not granted to them. Unrestricted battery usage is more hidden away than before since Android 14 QPR2. You need to press the text next to the toggle for background battery usage to access the menu for enabling unrestricted usage.

                applesbana It's not a Pixel or GrapheneOS issue. An iPhone won't fix issues with your carrier, unless the issue is that they don't follow standards in a way that only impacts certain devices.

                        Having VoLTE or Wi-Fi calling enabled when it doesn't work with your carrier will cause problems. Enabling LTE-only mode if you don't have working VoLTE will break cellular-based calls. Your carrier may have flaky LTE / VoLTE where it sometimes works but doesn't work in other cases. These are carrier issues.

                          I appreciate the detailed response.

                          Someone previously posted this which could lead one to believe it’s related to the pixel specifically (not graphene):
                          https://support.google.com/pixelphone/thread/264865035/pixel-7-pro-not-receiving-calls-after-march-2024-update

                          My specific location has no issue with missed calls when using an iPhone, so my anecdotal experience tells me it isn’t a carrier issue unless the carrier is misconfigured on my graphene pixel but correctly configured on my iPhone

                            I'm having this issue too. Lost many incoming calls, most of them actually.
