Galaxy S9+ Fingerprint scanner not working

[Android Central Question]

I have got my S9+ for a week now and over the past 3 days I am having an issue with the fingerprint scanner. When unlocking the device I get a message saying "The fingerprint scanner is not responding. Try again later."
When I go into setting and go to fingerprint settings I a message saying "An error has occurred with the fingerprint sensor. If this message appears repeatedly, restart your device."
This has happened many times ove the past 3 days. On other forums I see people are restoring phone to factory settings and so on. Is there any other quick fix without losing data?

The above is exactly the issue that i am facing too... i restart my device then it works...

There are some ways to test and see if there is any apps causing the sensor to stop working.

-Go to Samsung members apps
-Select Diagnostics
-Test Hardware
-Select Fingerprints
-Test it (While you are facing the issue)

If the issue precedes then you have to visit the nearest customer service center.

If its a hardware issue... how come it works once restarted?

If its a hardware issue... how come it works once restarted?

Same way some electronics suddenly work then don't then work again. Just return it.

Since its working after restart it must be a software issue.. hope Samsung fixes it asap.

 

[jacob124]

its not just about returning... its about the trust we put in samsung.... When such issues come , we tend to loose the trust...

After I got the same issue, I read from another forum about the same issue with S8. With S8, the problem was with fingerprint gestures. I turned mine off and like that forum said, my problem was fixed instantly.
Samsung members diagnostics didnt do anything - told to put my finger on the sensor, which obviusly didnt do anything as the sensor wasnt working. I submitted a ticket to Samsung tho.

Same problem here. Happened twice with my 3 days old device. Will take it to Samsung tomorrow ! Not quiet happy about it.

"Update 13/03 - As per another similar thread, the issue has been identified as linking with Finger Sensor gestures being enable (Settings > Advanced Features > Finger Sensor Gestures) and Samsung will be issuing a fix this coming friday"

Took it to Samsung and they said they are aware of the situation and its a software issue that will be fixed in a week's time with a software update.

 

[Skalp]

I just got an e-mail from Samsung stating the same: Samsung is aware that the fingerprint sensor isnt working as intended, but this is a software error and they hope to get it fixed with next software update. To fix the current error, they suggest on turning the fingerprinting gestures off and restart the phone.
So far, after turning off FP gestures, it has been working fine for me. I dont hold any grude against Samsung for this - **** happens...

I've go the same issue. Just had a chat with someone from Samsung using the live chat feature in Members app. She called me on my phone and collected my reg no and IMEI no and said they will deal with it.

I have had my S9 + for 4 days and have experienced this problem 2 times, hope they fix it in an SW update.

[JackyTran]

This problem will be fixed buy new SW version. Plan within this week and some country next week.

I've also been having this issue s9± with gestures enabled. Samsung support said return the phone but I think it may be software related. Will wait for a software update before I return it. "Fingerprint sensor is not responding try again later"

 

[slehan]

I have an older model and so far I haven't had any fingerprint scanner issues.

Seems fixed for me now after latest update.. using gesture's too. No issues for 2 days now (since updating)
