My j7 pro fingerprint not working

[Urzen]

I have bought this phone few days ago and everything was fine. Suddenly yesterday my fingerprint sensor wasn't responding. So I tried adding and removing the fingerprint but I couldn't access as it said 'an error and restart the phone' so I restarted it again but nothing happened. Here's things I did- 

1. Cleared data of fingerprint

2. Restarted the phone.

3. Had my phone reset again.

Then I dialed *#0*# that gave me the test. I click on the fingerprint test and it shows version:null, and 'fingerprint initialization fail'. I didn't do a factory reset because I'm not sure whether it's a hardware or simply a firmware issue. Please help me in this.

Before a Factory Reset I'd try clearing the phones system cache. 

If that and or a factory reset does not help then a Samsung Experience Store or Samsung Service Centre location can run a diagnostic on it.

I tried factory reset but nothing happened. I it a hardware problem?
