There are two types of underscreen sensors. The ultrasonic ones work great, even better than the back sensors I've used. Your finger taps and it's unlocked, simple as that.
The second type are the optical sensors, and these are the bad ones. You tap it and have to hold for the scan to complete, but it might fail because the screen is slightly smudged, or the light didnt hit your finger on the right angle, the room might be too dark/bright...
My experience differs. I found optical in display fingerprint to be quite reliable. It even happens to work with slightly wet hands. The room being too dark or bright has also never been an issue since my finger covers the sensor completely.
I guess it depends on the quality of sensor used by the manufacter. Pixel phones are known to have issues.
I purposely only registered the bare minimum of my fingerprint on my pixel 6. so long as I hold my digit correctly it unlocks every time, if I am off by a few millimetres (and I know when that is) it fails to unlock, I like it that way. Don't auto delete my preferred setting, ty
I have an ultrasonic one. When it decides not to recognize my finger it just doesn't. And sometimes it rumbles as if it had a wrong match while laying on the table on its own
idk my optical sensor works really well, it only fails if i place my finger at a weird angle, but ultrasonic's not going to fix that either
I like the optical ones as it works with wet hands
