Christian PietschI've become a fan of <a href="https://fedifreu.de/tags/GrapheneOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GrapheneOS</a> since I overcame my disgust of Google and bought a used Pixel phone. <a href="https://grapheneos.social/@GrapheneOS" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@GrapheneOS</a> is a great example of usable security.It's easier to install and use than most other aftermarket <a href="https://fedifreu.de/tags/Android" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Android</a> distributions I tried. And it has been a bug-free experience for me – until 1 or 2 weeks ago when the telephone stopped ringing when someone called. Phone calls did not even raise a full-screen notification any more. Only when I happend to watch the notification area was I able to see that someone is calling me. Most of the time, I only saw it when they had given up.Then yesterday the phone finally rang again! Today, this was broken again. Until I found a workaround! All I had to do was to disable WiFi telephony – a feature I had enabled right after I installed GrapheneOS and which had seemed to worked well.Update: According to <a href="https://grapheneos.social/@GrapheneOS" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@GrapheneOS</a>, the annoyance I described is not related to <a href="https://fedifreu.de/tags/GrapheneOS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GrapheneOS</a> but most likely caused by the carrier: <a href="https://grapheneos.social/@GrapheneOS/113046499971181147" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://grapheneos.social/@GrapheneOS/113046499971181147</a><a href="https://fedifreu.de/tags/WiFiTelephony" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WiFiTelephony</a> <a href="https://fedifreu.de/tags/WiFiCalling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WiFiCalling</a> <a href="https://fedifreu.de/tags/Android" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Android</a> <a href="https://fedifreu.de/tags/bug" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#bug</a>

Drew NaylorThere is no technical reason why Wi-Fi Calling/voice over Wi-Fi can't work on <a href="https://mastodon.online/tags/Linux" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Linux</a> phones. There could be a server running on the modem that sends your microphone audio to the other caller, and it can give received audio to userspace daemon which is then forwarded to the app using it. This would also apply to text messages. Only thing preventing this is <a href="https://mastodon.online/tags/BigTelecom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BigTelecom</a> not wanting to give access to anyone else besides <a href="https://mastodon.online/tags/Apple" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Apple</a> (if that's the case).<a href="https://mastodon.online/tags/LinuxMobile" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LinuxMobile</a> <a href="https://mastodon.online/tags/VoWiFi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#VoWiFi</a> <a href="https://mastodon.online/tags/WiFiCalling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#WiFiCalling</a>
