You are thinking of much later Nokia Androids.
Nokia X was not by HMD and was not Chinese made. It was produced in Nokia factories and was very similar to Lumix models - except the OS. It was available in Feb 2014 and Microsoft kept producing them for some months after they bought the factories, calling them Microsoft X.
The HMD devices were much later.
