Over at IFA 2015, Acer have launched a pair of modestly specced smartphones in Android/Windows 10 Phone parallel guises, with 'Z' denoting Android and 'M' denoting Windows 10 Mobile. Thus we have the M320 and M330, detailed below. No actual images yet of the 'M' devices, but you'll get the idea from the Android version press render. It's also not yet know whether these will definitely come straight out of the gate with Windows 10 Mobile - one assumes so...

Both phones come with a 4.5-inch FWVGA screen, 1GB RAM, 8GB built-in storage, 3G connectivity, WiFi, and Bluetooth 4.0. The main differences are that the M330 has a slightly higher spec processor, LTE and better front camera.

• Processor: Qualcomm Snapdragon 210 (MS 8909)
