It is believed this is due to the use of a third-party gel screen protector on the front of the phone. Samsung Electronics have acknowledged the issue and explained that the issue can occur when patterns of screen protectors which are included with some phone cases are recognized along with fingerprints.
"We are investigating the issue and will be deploying a software patch soon," a Samsung Electronics spokesperson told 7NEWS.com.au.
Customers have been told to cease using the Galaxy S10 fingerprint reader and instead use pin, password or face unlock until the fix is rolled out in a software update.
