I agree with you 100%. The way I tested for raised black glow in the darkOkay thank you.
I think it is a software issue that the LEDs are not right coded to turn off 100%. So if it will be a 100% hardware issue, why can the LEDs fully turn off on 100% brightness?
Compared my 12 PM with an iPhone 8+ and the blacks look better in every way but the LEDs still do not fully turn off until you raise the brightness to 90% or more.
