There has been some confusion regarding the availability of Nokia’s Glance feature, aka the on-screen clock which we covered recently in a tutorial post. The feature is coming to other Lumia devices via the Amber update, but we remember seeing rumors for “exceptions” on specific devices pop up, revolving around screen technology i.e. AMOLED vs LCD.
Nokia has gone now and confirmed that the Glance is basically coming to all Windows Phone 8 Lumias except the Lumia 520 and Lumia 521 (T-Mobile, US) due to “hardware restrictions”. While that would have been an awesome feature on the 52x series, evidently cutting hardware specs so low does have some consequences for feature parity.
Still, on the bright side the Lumia 620, 720, 810, 820, 822, 920 and 928 are all candidates for this feature, as long as their respective carriers push out the Amber firmware/GDR2 OS update to enable this cool trick. Our bet? Most carriers will allow this update to go out, much like previous Nokia ones, though it will be a staggered release as usual.
Glance allows users to check the time on their phones without having to turn on the screen. While it may seem like a throw away feature, as it turns out we use it surprisingly often. Current thought suggests it uses less battery life on AMOLED displays (Lumia 810, 820, 822, 925, 928, 1020) because it can independently turn on pixels for the backlight, as opposed to IPS LCD, which acts like one big light bulb. Still, what that means in real life is yet to be seen, but at least on AMOLED displays, the feature’s effect on battery has been negligible.
Nokia’s Amber update is expected to rollout to other Lumia devices later this summer.
