The Glance screen works without draining the battery too much due to the AMOLED screens. The Nokia Lumia 520/1/5 has a LCD screen, and thus is incompatible.
How it works is the Glance screen turns most of the pixels black. The AMOLED screens have the ability to turn off the pixels when they are black, so they aren't using battery by having the display ...
You probably need to update your Glance app. To do that, you can either:
Search for it in the Store (look under Nokia Collection)
Follow this link to send the app to your phone
Scan the QR code at the end of this WPCentral article) with your phone
Use a third-party app like Lumia Pusher to check for outdated Lumia apps
After that, go to Settings → ...
As an anecdotal counter-point to all of the other answers here, I own a Lumia 520. It was purchased in the US from AT&T. I am not sure how much or even if the hardware differs much from Lumia 520's elsewhere.
When the device received the Black update, it received the new Glance features as well. I can see all of my app notifications on the Glance screen....
I guess there will glance for lumia 520 soon as in the recent "Black" update there is a new extra under "extras + info" as Glance Pinboards App Agent 184.108.40.206. It looks like the hardware is made to match the glance screen and Microsoft is working on making the Glance app available.
First of all, any Developer other than Microsoft won't be having the .xap file of the previous versions of Glance Screen.
Secondly even if you have the .xap file and you place it on your SD Card, you will not be able to install it on your phone, because when you would try to install it, your phone checks the store whether there is a latest version of the ...
The SIM PIN screen is currently broken. So far the only fix I've found, is to remove the PIN code altogether. You can bypass the SIM screen by pressing the "back" button when you start up the phone. If you do try to enter the pin code and enter it, the phone will freeze and you will need to reset it to access the phone Again.
I have the same issue. The sim pincode screen is NOT working. It seems to have changed. Instead of Enter there is an OK button and the input is not shown.
By placing the sim card in turned on mode I can pass by the Sim Pincode screen!
The latest iteration of Nokia Glance will be what is packaged in the Lumia Black update. The newest features are highlighted here and there is no mention of landscape mode.
I'd suggest opening a ticket here if a similar ticket doesn't already exist. Representatives from the Windows Phone/Nokia teams do look at this forum and post feedback when available.
In that hack you simulate that your phone is a Lumia 950, does it have glance screen? I'm not sure, but have you tried this?
In order to enable glance screen in Lumia 650 / 950, follow these steps.
You can see the following options in the glance screen settings.
Mode: Here, you can set the time after the phone is locked when the glance screen appears ...
This seems to be caused by an other app, possibly the Microsoft Remote Desktop or Movie Moments app. Try opening and flipping the app to it's default orientation.
If you rotate Remote Desktop to be landscaped/flipped to the right side, your Glance screen will go back to normal without the need for a soft reset.
A soft reset should do the trick as well!
It happens because after a factory reset you need to manualy update the system apps that have been updated since the time your factory OS version was launched. Since you are in the Lumia Black version of the OS, you can't search for updates directly from the Store application, because this option are not available in the Black update. So, to search for ...
I think that Nokia simply built cheaper screens into the Lumia 520 than e.g. into the Lumia 920 (which also has an LCD screen instead of a AMOLED screen,) to get the great price. Thus, it would simply drain your battery... On AMOLED displays the battery drain is the most minimal.
