I've been using my S10+ for a few days now.
One thing I'm so disappointed with is the face unlock.
It kinda works.
And then it doesn't.
Really poor implementation.
Iphones are not like this. They have super sharp response and accuracy. Someone told me it's because they have about 4 cameras on the from or something and hence more accurate and sharp? And the S10+ has only 2.
Should I give up on face unlock?
(Almost every other part of the phone I'm loving.)
Face recognition works very well on my phone but I submit it's a different model to yours.
Perhaps consider deleting the face scan and try again setting it up.
As with all types of face recognition / iris scans etc they can sometimes be glitchy on all phones.
I wish you all the best with this situation.
