The screen size reaches 4" inches. Phones with smaller displays have the advantage of being easier to use with one hand. However, compared to phones with large screens, they provide a lower user experience. Nevertheless, if you don't plan to watch movies or play games on your phone regularly and just expect basic functionality, this size should be good enough for you. The disadvantage of LCD displays is the relatively lower color contrast displayed, as the technology cannot display absolute black well. Also due to the higher power consumption, LCD displays are no longer as common in phones. Even so, some manufacturers still equip their phones with LCD technology. However, modern smartphones are already using OLED technology. The advantage of LCD phones is that they tend to be cheaper to build than OLED technology.
