Screen turned Greyscale without option to go back to normal on Samsung J3 (2016) w/ Android 6

[succeedmr123]

Dear Dev,

I noticed while installing Lean Launcher debug version and a companion app, that somewhere were buried some options about "making a shortcut on the home screen for grayscale mode.

Howeverthroughout days of normal test usage,, tonight I inadvertedly touched near "arrow up" area at the bottom of my phones' homescreen, (not even seeing that greyscale shortcut at all) - the screen turned greyscale without any option of turning it off or visible shortcut.

Upon restarting the device, the screen is initially full colour, but after boot process finishes , home screen gets greyscale again.

No uninstall/reinstall helps, and can not find any background apps that are responsible for greyscale screen issue. Already checked developer option/colorspace, and the setting there is normal and the issue is unrelated to that.

Could you please confirm if greyscale screen could be an issue as described, and how to get back to normal, full color screen from that point?

Sorry for the late answer.

I don't think the launcher does anything that would make your screen grey. Maybe samsung has a setting for that? Since the issue was opened about 6 days ago, maybe it was solved already?
