When adjusting brightness (either manually via slider or auto brightness adjustment) around ~20% there is a big jump up/down in brightness. It's not a smooth transition, visually noticeable and very distracting. Looks like a flash (when it jumps up) or a idle phone screen dim (when jumps down). To test: Just slide the brightness bar really slowly from about 30% to 10%. You will hit a point where brightness jumps dramatically instead of smoothly. You can go the other way to from 10% to 30%, too. Should see brightness jump/dim somewhere around 18-20% Edit: Just realized you need to have Night Shift on and True Tone or it doesn’t do do it. Make sure those on. Both my phones do it. Anyone else experience this? Can I ask a few others to test this?
