Thank you for choosing Xiaomi products. The adhesive marks you’re noticing are the result of removing the protective film, and they can sometimes be caused by micro-dust that accumulates in the environment. These marks are usually harmless and can be easily removed. To clean them, simply use a soft cloth or alcohol pad to gently wipe the affected area. Please feel free to use your device. We recommend avoiding harsh chemicals or abrasive materials to prevent any damage to the surface. If the issue persists, please contact the local after-sales service center for further assistance. We are committed to ensuring your experience with our products is seamless and enjoyable.
