Bug?? By dialling*#0*# & After Checking Black colour Back button don't Work..

[Gst26]

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 ???

@Gst26 with the screen fully black, the on screen navigation buttons won't be visible so it was better thought to use the power key in this scenario.

Then why Samsung Pay app opens, when we Scroll 2-3 from bottom even when whole display is Black (Locked)..I am using this without any issue...

*#0*# is a special condition. Even when your phone is locked some capacitive sensors in the screen are still active. This is not the case with test mode, where all sensors are off.

Bro.. Navigation Buttons are not Visible in any Full Display Colours (RGBBlack) out of these Four, and Second it is not fixed to Back button only, you Scroll your finger upwards from anywhere in your Display, whether it is upper part, lower part or middle part it will work except Black....Hence it has nothing to do with Back Button or Navigation or Visibility of Navigation Buttons...

But you know the screen is on when in RGB, while if you test black it looks like the screen is off, nothing can be displayed on a pure black amoled which is actually all pixels off so even navigation keys cant be displayed. Coming to RGB you can clearly see the screen is on so there is no problem there.

Ok.. if I go by your statement...that when whole display is Black then it works as if the Screen is off and nothing can be displayed or all pixels off....then why Samsung pay opens when whole Display is Black and Screen is actually off from bottom with lock mode ??

Bro.. ok, now I'll go by this.... Does this Special Conditions applicable Specially for Black Colour only not for others ?? And this is not the case with test mode, where all sensors are off..then how these sensors are working with other Colours in test mode ???..

[Aashish]

Well that is the only caveat in this theory, the capacitive sensor are only turned off in Black mode.
