Very recently I have changed my phone to A12 from A10, however, the saddest part is I am unable add my fingerprint. Similarly, dual sim setting option is missing. Please suggest me the best solution of all for my mentioned issues.
Which means I should place my finger on power button instead of placing on fingerprint sensor camera lense? Sorry for burdening, but am asking all these things since am using this A12 for the first time.
I did exactly what you are suggesting, but the issue is my fingerprint sensor is not reading it. In fact, nothing is popping up when I place my finger on the camera
