|Sources: Amazon, ManufacturerSamsung Galaxy Z Fold6 vs Nokia XR21 5G
The Samsung Galaxy Z Fold6 is the flagship option here, offering a stunning 7.6" display that folds out for an immersive experience. In contrast, the Nokia XR21 5G is a mid-range phone with a solid 6.49" display, but it lacks the high-end features that the Galaxy delivers. In real-world usage, the Z Fold6's peak brightness of 2,600 nits makes it ideal for outdoor visibility, while the XR21's 550 nits can struggle in direct sunlight.
