The Xiaomi 15 Ultra undergoes strict professional inspection to ensure that it meets our high-quality standards before leaving the factory. The bumps, marks, or imprints that you can notice on the screen are due to the use of a thin and light four-curved screen design combined with ultrasonic fingerprint technology.
Under certain conditions, such as bright sunlight or when viewed from wide angles, you will observe slight bumps or changes in the screen's appearance. This is a natural characteristic of the design and does not affect the screen's functionality or your ability to use the phone normally.
These small visual variations are part of the advanced screen technology that helps improve the performance and durability of the device. Please rest assured that these marks will not interfere with your normal use of the phone.
