Ever since I bought my Samsung Galaxy A5 (2017), I've been using its Always-On Display feature, which displays a clock or calendar with unread notification icons, or one of four preinstalled images on the screen while it's in the "off" state (e.g. locked).
I'm using the Image option as you can see on the screenshot above. I've heard recently that Samsung phones are notorious for being susceptible to screen burn-in because of their AMOLED displays. Is that something I should be concerned about when using the Always-On Display feature?
