iPhone X screen randomly shuts off
Just got my BRAND NEW iPhone X after Apple replaced it for other issues. Recently the phone screen just turns off. But my music still plays and I’m unable to do anything. I know it doesn’t reset cause the music plays and I can still use Face ID after it turns back on after about 30 to 45 seconds. I haven’t dropped it or anything so I’m not sure what’s wrong. My IOS is the most recent one.
iPhone X, iOS 12
