There is very little to say about the resolution of the displays, the higher the better. But we must also take into consideration the type of screen with which a smartphone can be equipped. Obviously there are substantial differences between cheap smartphones and top of the range.

IPS (In-Panel-Switching) displays are an evolution of TFTs and are found on many of the best budget smartphones. They reproduce colors almost perfectly (thanks to the pixel backlighting) and have very “charged” whites. They do not have the problems of TFTs when changing the viewing angle and consume less energy than the latter. The only flaw? The low contrast ratio and the consequent poor reproduction of blacks.

AMOLED displays (OLED active matrix) are present on many top-of-the-range smartphones even if lately they are also widespread in the mid-range, such as on Samsung’s Galaxy or on the best buy Xiaomi. Their main feature is that the pixels emit their own light and do not need backlighting. They do not present major problems in color rendering but are less “legible” than IPS in sunlight. On the other hand, they reproduce very intense blacks, since the pixels are physically turned off to reproduce them and this results in a saving in terms of battery. The contrast ratio is the best possible. In recent years they have conquered everyone thanks to their incredibly beautiful and vibrant colors. More and more a must among the best top-of-the-range smartphone.

Furthermore, it should be noted that in many dual-SIM phones the second SIM slot is also used for microSDs, this means that you have to choose whether to use two SIMs or to expand the memory of the mobile phone (you cannot do both at the same time) .
