Lenovo is reportedly getting ready to launch an affordable smartphone under its Z6 series. The new phone is speculated to be called the Lenovo Z6 Lite aka Lenovo Z6 Youth. The device with a Snapdragon processor is expected to launch on May 22nd in China. While the device will include some decent specs at its price point, there’s something else well that catches the attention.
Lenovo VP Chang Cheng has shared a screenshot that shows the GPSTest chart which reveals that the smartphone will include GPS positioning accuracy of 1m, thanks to Allystar HD8040 GNSS chipset. This means the Lenovo Z6 Lite may have an accurate GPS experience on smartphones, not as other phones maybe but certainly better than those which don't have dual-frequency GNSS support.
There are times when you want to send your perfect location point but the GPS shows your location a few buildings away from the marker pointed on the map. So, here the latest support could come as a rescue, however, we are yet to gain more insight into it.
Several handsets today support L1 and L5 dual frequencies for accurate location tracking. But Lenovo Z6 Youth Edition is said to be the first cheapest smartphone to carry this support. The Allyster HD8040 is a multi-band GNSS (Global Satellite Navigation Systems) SoC that fully supports all signals on the L5 band besides just L1. This means the Lenovo Z6 Youth is going to be a dual-frequency-enabled device which will not only make use of L1/E1 frequency but also the L5/E5a. The L5/Ea bands are more advanced and thus less prone to multipath errors. This support will help the Lenovo Z6 Youth to offer up to 1m precision tracking.
Brief on dual-frequency GNSS -
The L1 + L5 dual frequency gives you a more accurate target location when using map navigation, even in complex terrains.
The GNSS support first came via Android Oreo (API 26), so it’s available for devices running this version or higher. At the moment, Huawei and Xiaomi are the only two vendors of note whose smartphones officially claim to support dual-frequency. However, based on the study of Sean Barbeau (source: Medium), Dual-frequency is supported on the Hong Kong (Snapdragon) variant of the Galaxy S10 as well. For your extra knowledge, the Xiaomi Mi 8 is the world’s first dual-frequency GNSS smartphone fitted with a Broadcom BCM47755 chip.
But in the case of cheaper Z6 Youth from Lenovo, it will use the Allystar HD8040 GNSS chipset. Note that Cheng already confirmed the presence of dual-frequency GNSS inside its yet-to-come Z6 Youth Edition a few days back and now the screenshot makes this news more concrete.
Based on the rumors, the Lenovo Z6 Youth will be powered by 8nm Qualcomm Snapdragon 730 Mobile platform featuring Kryo 470 CPU and Adreno 618 GPU. The device is said to support a waterdrop notch display with full HD+ resolution and supports HDR10 playback. It comes with a ceramic unibody design. It runs Android 9.0 Pie out-of-the-box with ZUI skin on the top. We are only a few days away from the said launch of the device. So stay tuned.
