Finger sensor not working, unable to unlock my phone

[magnet0]

Multiple times I deleted and re-register my finger however after a day or so the sensor won't recognize my finger to unlock my phone. None of my registered finger can unlock, I am using the default screen guard provided when i unboxed the phone.  The sensor always tells me to press hard on the sensor and yet fails.

I have to rely on using pin to unlock.

go to service centre and callibrate your fringer print sensor and that problem solved.

Yeah it worked, got it calibrated at the service center and could notice the change immediately, finger scan works now.

Wet the thumb a little and press it will work.If still not working then follow them as mentioned above

Yes, I have tried that as well and it won't work either, my other devices work well with finger scan to unlock so no issues with my finger being dry.

please remove screen guard first and then try
