I have very good accuracy with the fingerprint scanner when it comes to flat finger swipes, however not very good luck when it comes to one handed swiping with my thumbs.
I have repeated the one handed thumb swipe setup numerous times with varying results, but less the great.
With that said, I decided to setup a couple of up and down swipes and have pretty much solved the one handed swipe problem in my case.
Hopefully this can be of some benefit to others.

Is anyone else having problems with the fingerprint scanner? I'm trying to set it up to accept my print but it won't scan it.

No problems at all. Set up quickly and easy.
swipe slowly. good swipes take at least a full second it seems. mine set up just fine and works for unlocking the phone.
Mine was shockingly easy to set up.

Thanks! That's all it took...
You don't really need to exagerate the swipe, but the 1 second rule is not a bad one to follow.
Make sure that the way you swipe to enroll is roughly the same as the way you swipe to authenticate. Holding the phone in the same way helps a lot.
Swipe from the base of your finger pad, to the tip of your finger.
Always use a pulling motion. Do not push your finger across the sensor.
You can actually unlock the device whether you pull toward the bottom of the phone from the top, or flip the phone around and pull the other way during the swipe. This can be very useful when the phone is in a dock.
If your finger crosses the sensor at a strong angle, you may not be able to authenticate or enroll. Remember that the finger should be aligned as indicated in the animation.
Enjoy! And remember, this is serious security. It's way beyond the pattern lock or a pin. And yet, it's easier to use than either. How often can you add security and make something easier to use at the same time?
I know that mechanically, the S5 fingerprint scanner works DIFFERENTLY than the iPhone. But I'm curious how it compares in terms of reliability. For many people, the iPhone fingerprint scanner works virtually 100% of the time, so it is very quick and easy to unlock phone.
How is it on the Samsung Galaxy S5? Are you constantly having to reswipe your finger and readjust your grip to get it to work? Or, once you get the hang of it, does it reliably work the first time, every time?
Especially interested in hearing from people who have used both the S5 and an iPhone touch ID.
..
In order for it to ever be as good as the iPhone finger print scanner would they have to make some hardware upgrades or would it just be work with the software?
It's awful. Hardly ever gets mine right and I've scanned multiple fingers multiple times.

The trick is to scan just one finger multiple times. For example, you need to scan your thumb 3 ways - swiping down with the phone laying on a table, swiping down the way you would normally swipe with one hand and swiping down at an angle. This way the scanner will work much better, because it will have registered your finger in all possible situations you might swipe

Yeah I know that and have done. It's just a crap fingerprint sensor. OP is comparing to the iPhone. TouchID works flawlessly.
I second the previous posters comment on Touch ID, it is unbelievably impressive. It's worth the extra configuration time when you choose finger print scanning. My worry is that this may be patented to Apple? If so, is there an alternative for Android?
TouchID is easier to use and more accurate.. Its like put your hand in your pocket and your thump on the button and it just works.. While on S5, you have to swipe and sometimes it doesn't work, won't use it for my lock screen, still would use it for private mode
As per title.
Reason? Sometimes I would like to use different fingers with different orientation.
While I don't do this myself, you can achieve this by using more than one finger to train one of the "slots" on the phone. In other words, use one of your fingers to train up to about 50%, then switch to another finger. I just tried it out on my phone and it did recognize both fingers I used to train a given slot, but that was just a few trial unlocks I did in a more "controlled" way. I don't know what impact it'd have overall on accuracy in the various positions you often will hit the reader with in more "real world" use. Presumably it would to some extent mean it'd be less accurate or more picky, since there's less data about each "actual" finger in each finger "slot."
You can also do more than one orientation of a finger on the same storage slot. For example, Fingerprint one on my phone stores my right thumb horizontally, vertically, and diagonally, so I can hold my thumb in almost any orientation to unlock the phone. Slot # 2 has my right index finger in multiple orientations, etc.
You don't have to use one fingerprint storage location for horizontal thumb, another for vertical thumb, etc.
I'm rooted on APG1 and I would estimate the fingerprint scanner success rate at about 30% (that's being nice, it's likely considerably lower). I've deleted and recreated my fingerprint profile multiple times and with both thumbs. Same pitiful results.
Any suggestions, tips, or hacks to making this work better? If it's worth noting, I'm using the Incipio Performance lvl3 case which does have a protective lip at the top and bottom of the phone.
Thanks.

"When setting up a fingerprint on the Galaxy S7, it's important to remember to grab at least two pictures of your thumb going across the sensor diagonally. If all you do is move your thumb from top to bottom or from left to right, it's easy to create gaps in that complete picture. Adding a couple of diagonal captures during setup decreases the chances of this happening, which in turn makes your failure rate significantly lower when unlocking the phone every day.
The oval shape of the Galaxy S7 home button is the real key here. As long as you remember during fingerprint setup that the fingerprint being stored is the result of 13 different presses on the sensor, each capturing a long strip of your thumb and not much else, it becomes a lot easier to deal with. You won't be pressing your finger onto the Galaxy S7's home button the same exact way every time you unlock it, so don't put it on there the same way every time when you're registering it in the first place."
My unlock success rate is 19/20, I have even set up 2 fingers from one hand and 2 from other hand on very different positions, so it does not matter how I hold my phone it unlock perfectly almost all of the time
I've flashed resurrection remix 5.7.0 (Android M) on my sm-n910f, Everything works great except for one thing and the occasional crash. And that one thing is the fingerprint scanner, It only saves my left index finger. It works completely normal when saving the fingers but it only saves 1 finger even if I scan multiple fingers (not in the same finger of course) same finger everytime.
As I'm right handed unlocking my phone with my left index finger isn't all that useful so any of you guys got any help?
It worked fine in the stock ROM.
