It looks like "going live" is another thing we all have to figure out how to do to remain relevant in this very Facebook-driven world. But why would you ever want to go live? That's really up to you.
Portrait mode works with any dual-lens iPhone, as well as the single-lens iPhone XR, and lets you take impressive portraits with blurry, bokeh-filled backgrounds.

Do you want to assign a contact to look over your account, or would you prefer to have all your online memories fade away the minute you die? It's a tough decision, but with a little time, you can set up at least one of these options to ensure that your account isn't left to sit pretty without you for the rest of time.
