Fingerprint scanner is not working properly then I want use face lock also it's not secure because it's unlocking very fast even I close my eyes.. why Samsung didn't make good sensor for face lock even in flagship mobiles.. I call to Samsung service center about my device fingerprint not working properly.. they take my IMEI number then they say our technical team member will contact with you. But still now 5 days finish nobody call me.. please improve the service.. thanks
