Why is the screen of the Xiaomi 15 not sensitive when using the tempered film?

Question

Accepted Answer

Thank you for your support. The Xiaomi 15 is designed to offer a highly responsive touchscreen experience. However, when using a third-party tempered film, especially one that is too thick, you can notice a reduction in sensitivity. This is because the extra layer can interfere with the touchscreen's ability to accurately detect touch inputs. The device is originally equipped with a protective film that is specifically designed to maintain optimal sensitivity while providing protection. To ensure the best using experience, we recommend using the official protective film, as it is tailored to the phone's design and does not compromise the responsiveness of the screen.
