I agree! I feel that the physical fingerprint reader on the S9+ was so much faster and more reliable. It worked every single time and it made unlocking my phone a breeze, but this new on screen fingerprint reader on my S10+ is a joke! I hate it and I truly wish they would bring the old fingerprint reader back.
Looked at Gallery S20 & thought with new fingerprint tech be worth upgrade.
But they've not included it, same tech as S10 for fingerprint.
Rulre out that phone, no way I'm putting up with that again.
