Why is fingerprint recognition on the Redmi Note 14S abnormal?

Thank you for your continued support. The Redmi Note 14S has undergone strict professional inspection before leaving the factory, so you can feel confident in the performance and reliability of your device, knowing that it has been thoroughly tested for quality and functionality.
Due to differences in the manufacturing process, ordinary PET screen protective films can result in poor contrast and visible light transmittance, leading to fingerprint recognition issues. It is recommended to use a specific protective film made of SRF or OCF materials.
