Guys When you dial *#0*# from dial pad & check working of different-2 Components related to your Smartphone.. In this Process when you check all Four Colours option given here..

Back button works for RGB to return back to this Menu but for Black Colour this back button don't work to return back to this Menu, rather here you have to press power button to return back to this Menu...

Any logic behind this ?? Or this is a Big ???

String code are always for some testing.

I also checked during black Back key is not working.

When we select Black then I observe navigation buttons disappear or device act like it is in screen lock mode.

Your back is working in normal operation then I dont think you need to feel any issue.

Bro, I have to double swipe on every colour, think it might be happening only with you.

Usually after checking black screen you need to press power button to get out of Black Mode.
