Nokia's exclusive Glance Screen app, which allows users to check notifications on their Lumia Smartphone without actually having to unlock the device as such, will be receiving a major shot in the arm when it comes to features with the upcoming WP8 GDR3 update. Also called Bittersweet Shimmer (name given by Nokia, just like the previous Amber update a.k.a WP8 GDR2), Glance screen will have as many as 20 color options (in total) post the update. Moreover, your Lumia will show green or blue as options in Night Mode. While none of these new features are exactly groundbreaking, it never hurts to have a little more (colorful) customization options, something which Nokia has taken rather seriously with the WP8 Lumia lineup.
The Windows Phone 8 GDR3 update, scheduled to arrive later this year and slated to debut on the Lunmia 1520 later this month, will also bring a ton of other new features. One of the more significant of them is the added support for 1080p displays and quad-core processors, both of which will be found in the upcoming Lumia phablet.
