I’ve installed the latest build of /e/ (as of 11/11/18) on a Nexus 5. All is working well, except that the phone app will not start. It stops during startup and “keeps stopping” thereafter. I’ve tried multiple reboots and verified that the sim card is working. I’ve logged a bug but thought I’d mention it here in case there was a known fix or workaround. Otherwise, /e/ is very slick!
Ironically, I just pulled the sim card, tried again, and the app opens now. I’ll try again with a different sim (I did test the sim on an iPhone and it does work).
