It is fraud to me.
I've purchased "IMAK privacy glass screen protector for Xiaomi 15 Ultra" on 4th April 2026 and it mentioned "support ultrasound fingerprint recognition" on the website but turned out the recognition doesn't work. I sent an email to enquire about it on 12th April 2026 and was replied one day later:"Ok, we checked that you purchased the screen protector as Privacy version, there is no founctions for ultrasound fingerprint recognition, please understand this. " Then i replied the email on the same day with the screen capture of "support ultrasound fingerprint recognition" but still no response until today on 2nd May 2026.
