1. Fingerprint dobara register karein. Purana data nayi screen se match nahi karta. Settings > Security mein purane fingerprints delete karke naye sire se scan karein.
2. In-display fingerprint wale phones mein screen protector masla bana sakta hai. Mota ya kharab tempered glass sensor ki roshni rok deta hai. Protector utaar kar test karein, phir fingerprint-compatible protector lagwayein.
3. Screen ki brightness barha kar try karein. In-display sensor ko scan ke liye tez roshni chahiye hoti hai — kam brightness par woh ungli sahi nahi pakarta.
4. Ungli saaf aur khushk rakhein. Geeli, paseene wali ya zakhmi ungli nayi screen par mushkil se pehchani jati hai. Ungli aur screen dono saaf karke try karein.
5. Sensor par halka aur poora dabao lagayein. Nayi screen par sensor ka area sensitive hota hai — ungli ka markaz sensor par ho, zor se dabane ki zaroorat nahi.
6. Agar sab fail hon to screen ki quality ya fitting ka masla hai. Duplicate screen mein fingerprint aksar kaam nahi karta. Warning: screen khud dobara kholne ki koshish na karein — flex cable phat sakta hai. Usi shop par wapas jayein jis ne screen lagayi thi.
