In September, Microsoft began selling Acer's Windows 10 Mobile flagship phone on its UK store, pricing it at £449 as part of a bundle that included a mouse, keyboard and desktop docking station. But a few weeks later, that bundle disappeared from the Microsoft Store, and was replaced by a new listing for the Liquid Jade Primo handset on its own, priced at just £199.

Within hours, the device sold out, although Microsoft continued to promote it at that price on its Windows phone overview page for two weeks, despite the device remaining out of stock for all that time. Now, though, the Microsoft Store has replenished its stock of the Liquid Jade Primo, and is once again offering the handset for £199.

On the face of it, that seems like an incredibly low price for a mobile flagship - but it's worth bearing in mind that the Liquid Jade Primo isn't exactly a new device. It was originally announced in September 2015, although it didn't actually go on sale until earlier this year. Its key specs include:

5.5-inch Full HD (1920x1080px) AMOLED screen

5.5-inch Full HD (1920x1080px) AMOLED screen Hexa-core Qualcomm Snapdragon 808 processor

3GB RAM

32GB storage (plus microSD card support up to 128GB)

21MP rear camera with dual-LED flash and 4K (3840x2160px) video recording

8MP front-facing camera with Full HD (1920x1080px) video recording

Wi-Fi 802.11 b/g/n

USB Type-C connector

4G LTE connectivity

Dual-SIM support

2800mAh battery

156.5 x 75.9 x 8.4mm; 150g

Meanwhile, Acer is continuing to sell the Liquid Jade Primo on its own site for £449, which includes the docking station and a flip cover for the phone, but not the mouse and keyboard that came with Microsoft's bundle.
