Android Central Article on In-screen finger print sensors

Lol, disagree. First generation hardware and software, no doubt will get better.

The only thing I can say about the fps now (that I've received the updates) is that it's a little slower. At least now it works consistently. This phone rocks and a slightly slower fps I can live with. The weight of the ceramic is really nice. The phone feels substantial...but I digress.

...It's a solution without a problem...

That sums it up for 99%. Just because you can do something does not mean that you should.

A well placed rear FPS will ergonomically unlock your phone when picking it up out of a pocket, purse, or off of a table, without your having to look at the display.

Yes, if you are going to interact with your phone on a desk without picking it up, a front FPS is, providing it works quickly and as flawlessly as we have come to be accustomed to with a rear FPS, a better option.

But how often does one do that? If you're just checking the nature of a notification, that doesn't necessarily require an unlock, unless you opt for the most stringent security settings. And if you are going to do anything more than that in engaging the phone, you're likely to pick it up - at which point, you will naturally unlock it with a rear FPS in the single-step process of picking it up to use, as opposed to creating a 2-step process (either unlocking then picking it up, or picking it up then placing a finger on the display to unlock - which is not generally somewhere it lands naturally when first picking it up, so even were the full display a sensor it still requires that extra action).

The in-screen FPS is cool. It's new. But it doesn't offer an improvement in security, general utility, or ergonomics except in an infrequent case. Now if we get to a point down the road where the entire body of the phone on all sides is display, sure, we want this techonology rather than what would otherwise be a rear 'hole punch' fps, but until that day this is not something that should be in flagship phones - or in any event, at least, not until it is at least competitive in performance with the established rear FPS.

All valid points, thanks for sharing.
I don't feel as you do that it shouldn't be in flagship phones until it's competitive with rear FPS. My thinking is If someone doesn't run with the ball there is no one to chase. Competition and consumer demand will force the technology to evolve and improve. I realize that not everyone is willing to adust to the growing pains but I think the end result will be worth it.

Having used it for the last week or so it's actually quite good in it's performance and I have no regrets in this purchase.

I'm a passwords guy, so I do not care about how good or bad a phone's fingerprint sensor is.

I find myself sitting here turning my phone screen off and using my thumb to wake and unlock the phone, trying to find an issue at all. It's only slower if it has to wake the phone as well, not slow at all if my screen is already on. How fast is fast or how slow is too slow? Maybe I don't get it, or maybe I just have the perfect fps? I can even hold the phone upside down and scan my thumb at the top without an issue.

I hope everyone gets their phones working perfect that may be having an issue. I truly love this scanner way more than the S7 that I came from.

Everyone's experience will vary for a number of reasons. Also keep in mind that not everyone that is critiquing the FPS as it stands owns the device. Many are offering their opinion based on what they read and view online.

Umm, mostly agree except the ultrasonic is a improvement in security.
"Ultrasonic fingerprint technology works very differently to capacitive fingerprint scanners, which are only able to reproduce 2D images. 3D details are much more difficult to forge or fool than a 2D image, making the ultrasonic system much more secure. It goes without saying that ultrasound is also much more secure than optical fingerprint scanners, which have all but fallen out of favor."

They have to start somewhere but I do kind of agree. I haven't really had any problems with the in screen FPS on my S10+. It works well but it's not as consistently quick like it was on my S9+. It still works really well on my device though so I'm not regretting getting this phone. It was sort of silly for me to switch because I loved my S9+ and it worked perfectly well but I just like to get the new Galaxy phone every year. I'm not sure yet if in screen FPS will become the norm or if it will just die out. I have to say that I'm pretty happy with mine but if I'm being honest, the FPS on the back on my S9+ and S8+ did work a little better.
