On one side of the scale we have the fact of using technology AMOLED, with a better representation of colors, deep blacks and considerable energy savings. On the other side we have the step back in resolution with respect to the Xiaomi Mi A2, showing an HD + that is somewhat lower than expected.
However, neither one feature nor another has to do with the scarce brightness offered by the screen of the Xiaomi Mi A3. The fault is in Android One. It turns out that this operating system does not allow to use HBM technology, the high brightness mode, present in the Xiaomi phone. According to the data sheet of the Xiaomi Mi A3, the automatic brightness is capable of reaching 530 bits but Android One does not increase from 350, regardless of whether or not it is in automatic or manual mode.
