Looking at all the features that older phones uses to have compared to newer ones, I never hear anyone talk about the removal of the notification LED. I personally really liked that feature, being able to see if I got an email, a text or missed a call without turning on my phone was awesome. My Samsung note 8 had this feature, but to my knowledge, newer phones (in the major companies anyway) have abandoned this feature. Did everyone else unanimously agree they don’t care for this feature?
I think the problem that notification LEDs were designed to solve is just solved in other ways now, notably smart watches or the Always-On Display for OLED devices. Both consume more power than a notification LED would, but they also don’t require a dedicated physical space on the phone.
