Conclusion
The decision between these devices will first come down to what you can get hold of. Currently, the Xiaomi Mix Fold 2 isn’t available anywhere except China, which is a shame as it gives the Samsung Galaxy Z Fold 4 a decent competitor based on specifications.
The Xiaomi Mix Fold 2 is the slimmer of the two devices being compared here and it has features like an under-display fingerprint scanner, a larger internal and external display and a slightly larger battery, plus faster charging.
The Samsung Galaxy Z Fold 4 is the more widely available device though, whilst also offering features like an under-display camera, S Pen compatibility, better camera zoom capabilities, an IP rating and a fluid user interface. It might not be as thin as the Mix Fold 2, but the Z Fold 4 is still a lovely looking device, plus you’ll actually be able to buy it.
