My Iphone X has a feature that you can put the phone in night mode and allow only selected callers to call through while you are sleeping. The problem is that there is no indication in the upper task bar indicating that the feature is on. I missed some calls and couldn't figure out why. Looks like I forgot to take it out of night mode. Stupid that I forgot, but IOS should provide an indicator at the top, like my other Iphones had. End of rant. Irritating.
