Why does my S7 lock scree go blank?

[charlesxy]

I don't know if this has something to do with the fact that I used the power saving feature, but I used to be able to see text notifications and the weather once my screen locked after 30 seconds of non use.

But now, it goes completely blank.

Does anyone know why?

Thanks.

I assume you've already checked, but just to be sure -- does the problem persist after you turn off the power-saving feature?

Power Saver function on the S7 turns off always on display by default (the time and notifications on black screen when phone is locked). You have to customize the power saver setup to allow always on display to be active when you enable power saving.
