[deleted] 1) How can you add additional emergency phone numbers so you are able to call them even when the phone is locked? I tried but it doesn't work https://imgur.com/a/JiUfcKS
I just tried and it worked for me. Did you double tap the "Owner - Emergency Information" box above the dialpad and then navigate to the Contacts tab? I don't think you can enter the number directly into the dialpad, which seems to be what you did (I get the same "not an emergency number" message)
2) Is there an option to add a shortcut to the phone app from the lock screen? IIRC it's available on stock android.
Shortcuts, yes. Phone, I don't believe so.
