The Xiaomi 14 adopts a high-end flexible OLED display screen, which undergoes rigorous reliability inspection for screen quality. The phone also undergoes comprehensive inspection before leaving the factory. However, in extreme transportation conditions or due to drops and impacts during use, individual phones can experience abnormal screen displays caused by external force damage. If it's a case of damage upon unboxing, it's recommended to replace the phone. If such issues occur after long-term use, it's advisable to seek repair.
