Glance disappeared after reset to factory settings within wp8.1

Yesterday i installed wp8.1. Today i did a factory reset. After the reset wp8.1 is still installed. That dowsn't matter but now glance is missing.
Offcouse that was a nokia app which came with a nokia lumia update. How to get this back?

a factory reset removes the black/amber nokia updates, your only choice is to downgrade to wp8, reinstall the amber&black updates and upgrade to wp8.1
it takes about an evening but it is worth the effort

search the wp8.0 forums on here for an easy guide written at the time of gdr3 for people to go back to gdr2 using that nokia software for pc (i think it was called something like caresuite)

keep us updated if you run into trouble

I did a factory reset after installing the 8.1 and the glance and others apps from Nokia were installed automatically from the store... check there

So do you still show the Lumia Black update after the factory reset?

I didn't lose the Lumia Black update on my phones. A few of the Nokia apps needed reinstalling/updating afterward, though, but SysApp Pusher took care of that for me.

I'm gonna try that, thanks

Today I discovered that i didn't look good enough glance is still in the settings. Although it is not working but that was already the situation before upgrade to windows 8.1 and also not working anymore after factory reset.
I think the screen memory is broke. How much warranty do i have, it's a lumia 820 16 months old :(

After resetting I have glance under Settings>Display+Touch
