Why is my key light not switching off when battery saver is turned on?

Windows Central Question · Jan 6, 2015

My phone is running WP 8.1
UK version with O2 as the carrier.

Are you referring to the backlight of the touch buttons on the bottom? Are they even supposed to be disabled with battery saver turned on? Oo

Apparently this is a bug in 8.1 related to opening Device Hub. If you do this once, there is no fix other than a complete os reinstall.
