Can confirm that phone/text messaging abilities get shot yesterday/this morning after the recent update on 5 and 5a's. I've installed grapheneOS on 100's of phones over the past 2 years (absolutely love you guys and the work you do) and it seems this is now a chronic issue with customers emailing me all morning. Have a few 6, 6a, 7 pro devices that work just fine after the update, but the 5's seem to be an issue... as outlined. Spent nearly 2 hours with carrier technical support and after trying everything imaginable, finally re-flashed the OS, and the same issue happens. Have pulled the SIM card to a different device and it works fine in other devices. So this appears isolated to the device itself and happened right after the update.
