This is a point for which these two smartphones are engaged in a high-flying fight. As you can see in some of the values shared here, the two Amoled panels offered are of good quality. They display in Full HD + (2400 x 1080 px) at 120 Hz, but that of Samsung has a slightly higher resolution (411 dpi against 395 dpi). The screen refresh is not adaptive: you will have to choose 60 Hz or 120 Hz on both products.
Oled obliges, the screens benefit from an almost infinite contrast and zero afterglow time. The tactile delay is lower at Xiaomi (49 ms against 70 ms), but this is not felt in use on the two terminals. We appreciate the presence of Gorilla Glass Victus protection on both sides.
The S21 FE provides a higher peak light of 864 cd/m² against 806 cd/m² for its opponent. An important value, because it allows to maintain perfect readability even in very bright places. The difference is not huge, but it’s still taken, especially since the Samsung mobile is less subject to reflections. Good assets that the Samsung Galaxy S21 FE can boast of.
Once calibrated, the Xiaomi smartphone, on the other hand, displays almost perfect values. Whether on the delta E or the color temperature, they are better than those of the S21 FE, which are already very good. However, you will have to switch to Standard mode on Xiaomi and Natural on Samsung to take advantage of it. The very slight difference in final grade is also played on their factory values, but we can honestly declare equality between these two.
