I just recently purchased an Xperia XZ1 compact, and came across a small quirk in the developer options. I use one of the rendering options to switch the phone to black/white (color blind?) instead of full color.
When I restart the phone, it switches back to full color, even though in the developer options says that it's in black/white (i.e. the option is ignored). To set the phone back into black and white, I have to switch the option off and on again.
Before this phone I had an Xperia z5 compact, which didn't have this issue.
NB. The phone's language is in Dutch, if that matters.
