A new device, purportedly from Xiaomi, has appeared on Geekbench. Its combination of a novel model number and well-worn specs have led to rumors that it is a new addition to the POCO M4 series, albeit without 5G connectivity. Accordingly, it might be a pre-existing Xiaomi device rebranded to fit this description.

I like how mediatek and Xiaomi have combined here.
